The article represents the results for investigation of a new technology of complex soil consolidation and stabilization and reuse of the material from stripping of the existing roads (cold recycling technology) with portlandcement and enzyme agent Roadzyme (USA), which allows reducing the energy costs significantly and improving ecological situation. Cold recycling has a number of significant advantages before other means of reconstruction. The absence of environmental pollution is due to the complete use of the material of the old pavement. There is no need in disposal sites, and the volume of the new delivered materials is the minimum one and reduces the area of contamination, which is certain during opening of new borrow-pits and rock quarries. Transportation is very small, therefore the consumption of the energy is considerably reduced, as well as devastating impact of vehicles on the road network. Effect of the use of the agent “Roadzyme” is based on the activation of physics and chemical processes, which increase the strength, water resistance and frost resistance of the consolidated soils and materials, reducing material consumption at provision of the required elasticity modulus for pavement structure due to reduction of the thickness for pavement layers, the use of local materials and saving of binders and inert materials. The decrease is noted for the stiffness of the materials, strengthened by complex method (binder with the agent “Roadzyme”), compared to the treatment only with the binder, which allows forecasting the increase of the crack resistance.

The main indicators of 29 types of asphalt and polymer asphalt concretes prepared with the use of neat bitumens of 2 grades and 7 types of polymer bitumens have been determined and comparatively analyzed in the work. The bitumens of grades BND 100/130 and BND 130/200 produced by the Pavlodar petrochemical plant have been selected for preparation of the asphalt concretes, polymer bitumens and polymer asphalt concretes. 7 types of the polymers (Elvaloy 4170, Elvaloy AM, Kraton D 1192A, Calprene 501, SBS L 30-01 A, KUMHO KTR, Butonal NS 198) have been selected for the modification of the bitumens. Short procedure has been represented for the preparation of the polymer bitumens. 29 types of the asphalt and the polymer asphalt concretes have been prepared with the use of the above bitumens and polymer bitumens (asphalt concrete of type A - 7, asphalt concrete of type B - 15, stone mastic asphalt concrete SMA-15 - 1, stone mastic asphalt concrete SMA-20 - 6). The following main indicators of quality have been determined for the asphalt concretes and polymer asphalt concretes by testing in relevant laboratory devices: 1) rut depth at the temperature of 60 °С after 10 000 passages of the wheel (ST RK EN 12697-22-2012); 2) tensile strength at the temperature of -30 °С (pr. EN 12697-46-2012); 3) compression strength at the temperature of 50 °С (ST RK 1218-2003); 4) water saturation (ST RK 1218-2003). It is found out that the modification of the bitumens with the polymers increases essentially the main standard indicators of the asphalt concretes: rutting resistance, strength at high temperatures and low temperatures, resistance to the cyclic freezing and thawing (frost resistance). The reactive polymers Elvaloy 4170 and Elvaloy AM are the most efficient among the used ones.

The research article discusses a new method for the photocatalyst synthesis based on a mixture of titanium oxide - titanium oxyfluoride. The synthesis was performed by dissolving titanium metal in an acidified solution of ammonium bifluoride, followed by oxidation to the highest oxidation state and hydrolysis with ammonia to obtain metatitanic acid. The decomposition of metatitanic acid was carried out in a muffle furnace at a temperature of 380°C. It was found that during the precipitation of metatitanic acid, the titanium compound with the fluoride ion also passes into the precipitate, which, after calcination, transforms into titanium oxyfluoride. Photocatalytic activity was determined by the oxidation reaction of the methyl orange dye upon irradiation with ultraviolet radiation. The source of ultraviolet radiation was a DRT-125 lamp with a wavelength in the range of 200-400 nm. Suspensions containing 60 mg/L of the dye and various contents of the photocatalyst in the concentration range of 1-7 g/L were subjected to oxidation. The construction of the calibration graph and the determination of the concentrations were carried out on an SF-2000 spectrophotometer at a wavelength of 466.4 nm. The operating wavelength was determined by scanning the solution in the wavelength range of 200-800 nm. It was found that as a result of oxidation, the solution pH shifts to the acidic side to 3.5, which leads to a shift in the wavelength of the maximum absorption; in this regard, the solutions pH was adjusted to the same values.

This work shows the data regarding the elemental and chemical group compositions of the road bitumens. The short characteristic has been shown for the components of the bitumens - the asphaltenes, the resins and the oils. The properties have been described for the bitumens on which they have the direct impact. The description is given for the micellar model of the bitumens from the point of view of the colloid chemistry. The analysis has been performed for the results of the study by other authors for the asphaltenes of a bitumen and an oil. The group chemical compositions are given for the bitumen of the grades BND 50/70, BND 70/100 and BND 100/130 produced by the plants of Kazakhstan. It has been shown that the content of the asphaltenes in them is from 15.8% to 24.3%; in most cases, the content of the asphaltenes is within the range of 20-25%, i.e. the asphaltenes nanoclusters are almost a fourth of the bitumen by weight. The brief description is given for the best known polymers used for the modification of the road bitumen: 1) the reactive polymers Elvaloy 4170 and Elvaloy AM; 2) the polymers of the group SBS - Kraton D 1192A, Calprene 501, SBS L 30-01 A, KUMHO KTR and Butonal NS 198. It is proposed to consider the bitumen and the polymer bitumen as the peculiar nanodisperse systems. The structures are described for the polymer bitumen nanodisperse systems occurring during the modification of the road bitumen with the polymers of the above two groups.

The present work is devoted to mathematical modeling of the process of the hereditary materials relaxation. Nonlinear integral equation of a hereditary type is proposed. The Abel kernel with two unknown parameters is adopted as the kernel of the integral equation: α∈(0,1),δ>0. Two new characteristics were introduced: 1) experimental rheological parameter of relaxation; 2) calculated (model) rheological parameter of relaxation. Using the least squares method, expressions are obtained to determine unknown parameters of the Abel kernel. A mathematical expression is given to approximate the process of the hereditary materials relaxation. Using examples of rheonomic materials different in structure (polyurethane matrix, propellant, polyoxymethylene, fiberglass), it is shown that the proposed methods allow to determine Abel kernel parameters with a high accuracy and to model the process of relaxation of rheonomic materials different in structure during a long period of time: from 102 to 1.8·106 seconds (500 hours).

A comparative analysis has been performed in this work for low temperature strength of 31 types of the conventional (non-modified) and modified road asphalt concretes. The neat bitumens of the grades BND 70/100, BND 100/130 and BND 130/200 have been produced by the Pavlodar petrochemical plant from the crude oil of the Western Siberia (Russia) by the method of direct oxidation and they satisfy the requirements of the standard ST RK 1373-2013. The polymers Elvaloy 4170, Elvaloy AM, Kraton, Calprene 501, Butonal NS, SBS (L 30-01 A), KUMHO KTP and crumb rubber have been used for the modification of the bitumens. The modification of the bitumens has been performed in the laboratory of Kazakhstan Highway Research Institute. The modified bitumens satisfy the requirements of the standard ST RK 2534-2015. The conventional and modified asphalt concretes satisfy the requirements of the standards ST RK 1225-2019, ST RK 1223-2019, ST RK 2028-2010, ST RK 2373-2019 and GOST 31015-2002. The strength of the asphalt concretes at uniaxial direct tension at a constant strain rate of 1 mm/min at the temperatures of -10 °С, -20 °С and -30 °С determined in the device TRAVIS under the standard EN 2697-46 has been accepted as a characteristic of their low temperature strength. It is found out that various modifiers affect the asphalt concrete strength in different ways: a degree of impact depends both on a type of an asphalt concrete and a modifier, as well as on a negative temperature value. Some modifiers increase, and some of them decrease the strength of the asphalt concretes at low temperatures compared with the original asphalt concretes. Among the modifiers the polymer Elvaloy AM has been found to be the most efficient at low temperatures. The asphalt concretes of type B with the bitumens of grades BND БНД 100/130 and BND 130/200 at modification by the polymer Elvaloy AM had the biggest strength at all the considered low temperatures: at -10 ºC – 6.79 MPa and 6.43 MPa; at -20 ºC – 7.57 MPa and 7.87 MPa; at -30 ºC – 7.35 MPa and 8.86 MPa. The stone mastic asphalt concretes 15 and 20 with the polymers and without them at all the considered low temperatures practically had the strength not higher than the basic asphalt concretes of type B with neat (original) bitumens of grades BND 100/130 and BND 130/200.

A comparative analysis of the low temperature resistance for a nanocarbon bitumen and other 30 neat and modified bitumens has been performed in the work. The stiffness at the temperatures of -24°С, -30°С and -36°С under technical system Superpave has been accepted as an indicator of low temperature resistance of the bitumens. The stiffness of the bitumens has been determined on a bending beam rheometer (standard ASTM D 6648-08). Before testing the bitumens have been subjected to the double artificial aging: short-term aging – under standard AASHTO Т 240-13 and long-term aging – under standard ASTM D 6521-08. The nanocarbon bitumen has been prepared in the laboratory of the Kazakhstan Highway Research Institute (KazdorNII) with the use of a road bitumen of the grade BND 70/100 produced by the Pavlodar petrochemical plant (PNHZ) and a nanocarbon powder (2% by weight) manufactured from a coal rock of the deposit “Saryadyr” “Corporation “ON-Olzha” LLP, Akmola region, Kazakhstan). The nanocarbon powder (150-200 nm) has been manufactured by three-stage size reduction of the coal rock: I – a mechanical dispergator (up to 2-3 mm), II – an aerodynamic mill (up to 20 mcm), III – a reactor with a rotating electromagnetic field. The neat bitumens of the grades BND 50/70, BND 70/100, BND 100/130 have been produced by the plants of Kazakhstan and Russia; they satisfy the requirements of the standard ST RK 1373-2013. The modified bitumens have been prepared in the laboratory of KazdorNII with the use of the neat bitumens, 7 types of the polymers, crumb rubber and polyphosphoric acid and they satisfy the requirements of the standard ST RK 2534-2014. It has been determined that the nanocarbon bitumen is one of the most resistant at the low temperatures: -24°С, -30°С and -36°С.

The main standard indicators (penetration at 25 °С, ductility at 25 °С, softening point, Fraas point) have been determined and analyzed in this work for bitumens of the grades BND 100-130, BND 130-200 and 21 modified bitumens. The neat bitumens of the grades BND 100-130 and BND 130-200 have been produced at Pavlodar petrochemical plant from the oil of Western Siberia (Russia) by method of direct oxidation and they satisfy the requirements of the standard of Kazakhstan ST RK 1373-2013 “Bitumens and bituminous binders. Oil road viscous bitumens. Technical specifications”. The polymers Elvaloy 4170, Elvaloy AM, Kraton, Calprene 501, Butonal NS 198, SBS (L30-01A), KUMHO, crumb rubber and polyphosphoric acid have been accepted as modifiers. The modification of the bitumens has been performed in the laboratory of Kazakhstan Highway Research Institute (KazdorNII). The manufactured modified bitumens satisfy the requirements of the standard of Kazakhstan ST RK 2534-2014 “Bitumens and bituminous binders. Oil modified road bitumens. Technical specifications”. The standard indicators of the neat and modified bitumens have been determined in the laboratory of KazdorNII according to the following standards of Kazakhstan; penetration at 25 °C - ST RK 1226-2003 “Oil bitumens and binder materials based on bitumen. Method for determination of needle penetration depth”; ductility at 25 °С - ST RK 1374-2005 “Bitumens and bituminous binders. Method for determination of ductility”; softening point - ST RK 1227-2003 ‘Bitumens and bituminous binders. Determination of softening point by ring and ball method”; Fraas point - ST RK 1229-2003 ‘Oil bitumens and bituminous binders. Method for determination of Fraas point”. It is found out that all the applied polymers and polyphosphoric acid when adding them to the bitumens decrease the penetration thereby changing the grade of the bitumens. After modification 43 % of the polymer bitumens convert to the next grade, 43 % change their grade for 2 units and 14 % have the grade more viscous for 3 units. All the considered polymers and polyphosphoric acid increase the softening point thereby improving the high temperature resistance of the bitumens. It is determined that at modification of the bitumens of the grades BND 100-130 and BND 130-200 the increase of the Fraas point is 32-45 % and 28-93 % respectively. Most (71 %) of the polymers and polyphosphoric acid increase the Fraas point (decrease the low temperature resistance). In four cases out of twenty-one (19 %) the modification does not practically vary the Fraas point. The positive effect has been obtained only in two cases (10 %) for the modification of the bitumen of the grade BND 130-200 - the decrease of the Fraas point. The increase of the ductility for the bitumens has been recorded only in three cases (14 %) for their modification. In four cases (19 %) the initial ductility remains constant. In other cases (67 %) the ductility of the bitumens is decreased from 26 % to 86 %.

This paper evaluated the potentialities of a green and biocompatible rejuvenator agent (HR) in conferring an appreciable resistance against the effects caused by artificial aging on a given bitumen. Both neat and aged bitumens were analyzed and compared to analogous samples modified with HR. Control samples containing a vegetable oil as softening agent were also tested for comparison. The tested samples were subjected to a second aging cycle. Structural differences between the samples were carried out through an inverse Laplace transform of the NMR spin-echo decay (T2) and self-diffusion measurements by pulsed gradient spin echo nuclear magnetic resonance (PGSE-NMR) spectroscopy. In addition, dynamic rheological analyses were conducted to determine the dependence of the gel-sol transition temperature on both the type of additive and ageing process. The present study clearly highlighted the fact that artificial ageing, realized here by the rolling thin film oven test (RTFOT) and the pressure ageing vessel (PAV) test, induced important structural modifications. The analysis of relaxation times and self-diffusion coefficients indicated that ageing promoted the formation of molecular populations characterized by a shift of the distribution toward higher molecular weights compared to unaged bitumen. Diffusion data showed also an Arrhenius-like temperature dependence. A correlation between all the data was attempted to understand the role of the investigated additives. The eco-friendly biocompatible rejuvenator helped not only to restore the structure of the aged bitumen, but even slowed down the processes of a second aging (aiming at the first aged sample).

The paper represents the research results for the process of crude oil-contaminated soil neutralization with the use of a neutralizer obtained on the basis ofhumic substances. Using physical methods (gas and liquid chromatography, fluorimetry, atomic absorption spectrometry, IR spectrometry), the element and group compositionswere determined for the crude oil-contaminated soil, neutralizer, and neutralized soil. Optimal parameters were determined for the process of the crude oil-contaminated soil neutralization under laboratory conditions:weight ratios of the crude oil-contaminated soil, neutralizer and water, and the temperature and neutralization process duration. The technological scheme was developed for the neutralization of the crude oil-contaminated soil in field conditions. It was found that low-boiling point hydrocarbon fractions (C12–C17) disappear completely at neutralization, the content of high-boiling point hydrocarbon fractions (C20–C23) is essentially increased, and the content of oil components and metals, including the toxic ones, is decreased. The engineering characteristics for nine mixtures of the stabilized soil, containing the neutralized soil, were evaluated under laboratory conditions and the conditions were determined for their use in road construction (with regard to road category, characteristic pavement layer, minimal air temperature). An experimental road section was constructed with the use of the stabilized soil with neutralized soil (40%).

The objective of the paper is to show that there is an important mechanical characteristic of an asphalt concrete called as a long-term strength which is determined experimentally in an easy way under scheme of direct creep, and using it one can model the deformation and failure of the asphalt concrete at various types of loading. For this purpose the long-term strength is investigated experimentally for a hot fine-grained asphalt concrete at uniaxial tension under stress from 0.0081 MPa to 3.0 MPa within the range of temperatures from +60 °C to −24 °C. The experiments have been performed in a specifically invented and assembled device which allows determining the mechanical characteristics of materials at tension at various temperatures and types of loading. It is found out that without exclusion for all considered temperatures long-term strength of the asphalt concrete is described by power function with a high accuracy. Exponent characterizing a rate of variation for failure time at variation of stress is increased with the temperature increase: failure time is decreased for 3–7 orders (depending on temperature) at the stress increase for one order. Long-term strength of the asphalt concrete can be also described on the basis of the thermal fluctuation theory. It is found out that activation energy of failure does not depend on stress and temperature, and it is equal to 162.8 kJ/mol; the pre-exponential constant characterizing average time between neighbouring thermal fluctuations depends on stress as well as on temperature; meanwhile the more the temperature the less the effect of stress. Potentials for use are also shown for long-term strength of the asphalt concrete for modeling of the processes of its deformation and failure at loading with a constant rate and in conditions of the thermal stress restrained specimen test.

Because of the aged binder properties, high Reclaimed Asphalt Pavement (RAP) content asphalt mixtures are more susceptible to cracking failures than virgin mixtures. Thus the production of recycled Hot Mix Asphalt (HMA) for cold climate regions, in which asphalt pavement is subjected to severe thermal stresses, needs more considerations. The present paper deals with three recycling agents for producing recycled HMA with standard quality for paving applications in cold climate regions. These additives were three eco-friendly bio-based materials from which two of them were derived from Amine and Oleic acid reaction and the third was a solid compound of Furanone. As a complete study, the research plan consisted of both binder and mixture-phase tests investigating the efficiency of the additives as a recycling agent, particularly for cold region HMA paving applications. In the binder phase, the additives were investigated in two different scenarios: (I) first the reference asphalt binder was aged then the additives were added (2) first the additive was added to the virgin binder then the compounds were aged. This was mainly for investigating the efficiency of the additives as a softening agent. Considering the goal of this research, all the tests were carried out following the testing methods of the Republic of Kazakhstan and the obtained tests’ results were compared to the requirements of its technical specifications.

This paper represents and analyses the experimental data for investigation of freezing and associated temperature and moisture variations in subgrade of “Almaty-Bishkek” highway (2013–2016). Experimental data regarding temperature and moisture have been obtained by special sensors which were installed in different depths of a vertical hole, drilled in a multilayer pavement and subgrade of the highway. Measuring of temperature has been performed according to the principle of thermal resistance variation, and measuring of moisture has been performed in accordance with the principle of dielectric permeability. It was stated that temperature in points of subgrade is varied only in an annual cycle in south-eastern region of Kazakhstan, daily cycles are not available. Amplitude temperature values are decreased with the depth increase and lag in time is increased for the graphs of temperature variation with the depth increase. The character of variation and maximal value of freezing depth can be different depending on the character of air temperature variation and possible interchanging of cold and warm periods in winter. The temperature can be decreased lower than 0 ℃ in the top part of subgrade in winter periods. In such a case, sharp decrease for quantity of liquid moisture occurs, i.e. part of moisture transforms into a solid condition (ice). Quantity of moisture becomes more after thawing than it was before freezing. The value of this accumulated moisture content is connected with the duration of frozen condition for the top part of subgrade and maximal freezing depth of a highway.

Physical and chemical indicators of bitumen quality of grade BND 70/100 with the added carbon nanopowder 2% by weight have been studied by laboratory test methods and analysis. High reaction ability of nanopowder particles and concentration of excess surface and internal energy in them have been determined, which provide the increase of low-temperature resistance, aggregate strength, and improvement of rheological properties of nanostructured bitumen. Essential structure variation has been proved: the increase of asphaltenes and oils content for 9% and 7.2% respectively due to the decrease of resins for 16.2% by weight. Methods have been discussed for preparing a liquid nanocarbon mix, adding of the mix into bitumen and homogenization of the bitumen. Some economic indicators have been represented which influence essentially the reduction for the cost value of the nanostructure bitumen.
