The paper presents the issue of resistance to permanent deformations of bridge pavements placed upon concrete bridge decks. In Europe, bridge asphalt pavement usually consists of a wearing course and a protective layer, which are placed over the insulation (waterproofing). Protective layers of bridge pavement are commonly constructed using low air void content asphalt mixes as this provides the suitable tightness of such layers. Due to increased binder content, asphalt mixes for bridge pavement may have reduced resistance to permanent deformations. The article presents test results of resistance to permanent deformations of asphalt mixes for the protective layers. In order to determine the composition of mixtures with low air void content and resistance to permanent deformation, an experimental design was applied using a new concept of asphalt mix composition. Twenty-seven different asphalt mixture compositions were analyzed. The mixtures varied in terms of binder content, sand content and grit ratio. Resistance to permanent deformation was tested using the laboratory uniaxial cyclic compression method (dynamic load creep). On the basis of experimental results and statistical analysis, the functions of asphalt mixture permanent deformation resistance were established. This enabled a determination of suitable mixture compositions for protective layers for concrete bridge decks.

The paper presents the proposition of special assessment of low temperature requirements for bitumens in the region of Central and Eastern Europe where there is a moderate transitional area from sea to the continental type of climate. The results of the research program conducted on the road neat bitumens, Styrene-Butadiene-Styrene polymer and polymer-rubber modified bitumen, and multigrade bitumen types were presented and discussed. Based on the Superior Performing Asphalt Pavements Performance Grade procedure for low temperatures, climatic zones in Poland were developed and compared to analogous zones for other countries from the Central and Eastern Europe region as Estonia and Belarus. The results of functional Performance Grade tests and European standard test of bituminous binders were analysed. It was concluded that some of the bitumens were not meet the performance requirements in the range of low temperatures by Superior Performing Asphalt Pavements Superpave specification and the low-temperature properties of those bitumens should be improved.

In the course of manufacturing, transport and installation, road bitumens and asphalt mixtures can be exposed to the impact of elevated process temperatures exceeding 240 °C. This mainly applies to the mixtures used for road pavements and bridge deck insulation during adverse weather conditions. The heating process should not change the basic and rheological properties of binders and the asphalt mixtures that to a degree cause the degradation of asphalt pavement durability. The work involved analyzing the properties of non-modified bitumens and SBS polymer modified bitumens, heated at temperatures of 200 °C, 250 °C and 300 °C for 1 h. Next, the asphalt mixtures were heated in the same temperatures. Based on the developed Overheating Degradation Index (ODI) it was demonstrated that polymer-modified bitumens were characterized by higher overheating sensitivity A(ODI) than non-modified bitumens, which was confirmed by mixture test results. Overheating limit temperatures T(ODI) were determined, which in the case of polymer-modified bitumens are up to 20 °C lower than for non-modified bitumens. When the temperature increases above T(ODI), loss of viscoelastic properties occurs in the material which causes, among other effects, a loss of resistance to fatigue cracking.

Asphalt mixtures are commonly used for the pavement construction for national roads with a high traffic load, as well as local roads with low traffic load. The constructions of local road pavement consisting of thinner, more flexible layers located on less stable subbase than the pavement of national roads, require reinforcement with asphalt layers characterized by increased fatigue life. Technologies that allow quick repairs and reinforcements, while improving the durability of the road pavement are being sought. Such technologies include the use of modifications of asphalt mixtures with special fibers. The paper presents the results of investigations of the properties of asphalt mixtures modified with innovative basalt-polymer fibers FRP. On the basis of the obtained test results according to the Marshall method, stiffness modulus and fatigue durability, the technical properties of asphalt mixtures with FRP fibers addition were improved. This technology significantly increases the fatigue life of asphalt concrete dedicated for repairs and reinforcements of road pavements.

SummaryPavements made of cement concrete, used for road constructions, are damaged during use. This applies to both the pavements of rural and forest roads with very low traffic loads, as well as road pavements with high traffic loads. One of the most effective ways of repairing damaged concrete cement pavements is through placing an asphalt overlay on a concrete slab. In order to increase the fatigue life of the asphalt overlay, asphalt mixtures are modified with fibres. One technological solution is to use FRP (Fiber Reinforced Polymer), an innovative material with improved properties. The aim of this paper is to assess the impact of asphalt overlays modified with a new type of fibres to strengthen the durability of weakened cement concrete pavement structures. On the basis of the conducted analyses, it was shown that the use of an asphalt layer reinforcement increases fatigue life, for both 15 cm thick prefabricated slabs and a typical road pavement for average traffic made of 25 cm doweled and anchored concrete slabs. There was a significant increase in the fatigue life of the concrete pavement structure as a result of modifying the overlaid asphalt mixture with FRP fibres.

Over the course of operation, asphalt road pavements are subjected to damage from car traffic loads and environmental factors. One of the possible methods of strengthening damaged asphalt pavements may be the application of an additional rigid layer in the form of a cement concrete slab with continuous reinforcement.This paper presents a material-technological and structural solution for composite pavement where a cement concrete slab with continuous HFRP bar reinforcement is used for strengthening. Based on laboratory tests, the serviceability of composite bar reinforcement of rigid pavement slabs was shown. A design for strengthening asphalt pavement with a concrete slab with steel bar and corresponding HFRP bar reinforcement was developed. The composition of a pavement cement concrete mix was designed, and experimental sections were formed. Based on laboratory tests of samples collected from the surfaces of experimental sections and the diagnostic tests carried out in “in situ” conditions, the authors will try, in the nearest future (Part II: In situ observations and tests), to confirm the effectiveness of strengthening asphalt pavements with cement concrete slabs with HFRP components.

The article concerns the properties of bitumens and modified binders manufactured in Poland and used in Central and Eastern Europe for road paving. The aim of the article is to evaluate the properties of bituminous binders in terms of the climatic conditions of Central and Eastern Europe, taking the Polish climate as an example. In order to obtain a qualitative assessment of binders taking into account their role in the formation of road surface and its operating conditions in a wide range of temperatures, extensive research of the binders most commonly used in the construction of asphalt pavement were carried out. Aside from the results of standard tests, this article also presents the results of studies determining the functional properties of binders according to the SUPERPAVE method. Based on the results, it was found that the bituminous binders meet the requirements specified in European standards and technical guidelines. The temperature range of viscoelasticity of all the tested bituminous binders is very wide and exceeds 80 °C. However, in view of the Polish climate, an unfavourable phenomenon is a shift in the temperature range of viscoelasticity towards higher operating temperatures, at the same time lowering the binder performance at low temperatures.

Environment conservation and diminishing natural resources caused an increase in popularity of the application of renewable bio-origin resources for the construction of road pavement. Currently, there are known additions of bio-origin materials for bitumen modification. Such material is also used as a flux additive for bitumen or as a rejuvenator once working with reclaimed asphalt pavement (RAP). This paper presents research dealing with asphalt mixtures with RAP modified with a bio-agent of rapeseed origin. The main idea of the conducted research was to apply more RAP content directly to the batch mix plant without extra RAP heating. The RAP used in this study was milled from a base asphalt layer; the addition of RAP stiffens new asphalt mixtures. A bio-agent, due to its fluxing action, was used to support the asphalt mixing process and to decrease the over-stiffening of the mixture caused by RAP addition. This research includes bitumen and mixture tests. For the bitumen study, three different bitumens (35/50, 50/70, and 70/100) were tested in a dynamic shear rheometer (DSR) for complex modulus G* and for phase angle |δ| in the temperature range 0–100 °C. The reference mixture and mixtures with 2.5% bio-agent were tested to assess the influence of RAP and the bio-agent addition on the asphalt mixture properties. Low temperature behavior (TSRST), stiffness, and fatigue resistance (4PB) were tested. Based on the bitumen test, it was determined that even a low rate of bio-agent (2.5%) beneficially changes bitumen properties at a low temperature; moreover, polymerization processes occurring in the second stage of the process improves bitumen properties at a high operational temperature. The research with these asphalt mixtures demonstrates that the bio-origin flux acts as a rejuvenator and allows for an application of 30% cold RAP. Thermal cracking resistance of the mixture with RAP and 2.5% bio-agent improved. The bio-agent removes unfavorable stiffening of RAP and increases the fatigue resistance of the asphalt mixture.

Construction of modern and durable asphalt and cement pavements requires high quality materials and suitable technologies that take into account sustainability concerns which are related to the environmental protection, mitigation and compensation for road construction effects on surface water and groundwater, soil, air, wildlife, landscape, vibration and noise. The objectives of this paper are to identify possible development directions of materials and technologies in road construction in the time perspective of approximately 30 years. In order to achieve that goal a nationwide Delphi survey with 150 invited experts was deployed. The study concluded that binding materials with improved viscoelastic range – and often with specific modifications – would continue to play a leading role. Furthermore, technologies that enable monitoring the state of road pavement condition in a continuous manner would be used to a greater range. Introduction of sensors into the pavement network would lead to the construction of “smart” roads while spreading of nanomaterial technology would improve the durability and reliability of road pavement construction.

Pavement is one of the basic elements of a bridge structure. In Europe and Poland pavements for engineering objects are made in the asphalt technology. Requirements for ensuring the sustainability of the entire object also refer to pavement. Fatigue life is one of the parameter that must be satisfy but there is no requirements connected with it. It is directly related to the stresses and strains which occur in the pavement. Based on a state of art and using calculation results of software with finite element method (FEM) the strains in characteristic points of the bridge pavement were presented. Strains in pavements on the soil, concrete and steel deck were compared. One of the classic and one of the modern criteria for fatigue life were described. Calculation models for fatigue life of asphalt pavement does not classify separately bridge pavements. A typical technology and materials used in the bridge deck pavements were presented. Fatigue life of asphalt bridge pavements were estimated. The analysis of the results and evaluation of the adequacy of fatigue life models were made

W artykule przedstawiono zagadnienie wpływu zwiększonej ilości dodatku destruktu asfaltowego na odporność mieszanek mineralno-asfaltowych na działanie wody. Badaniom poddano mieszanki o ciągłym uziarnieniu typu betonowego i nieciągłym uziarnieniu typu SMA. Zbadano betony asfaltowe o zawartości destruktu do 90% oraz mieszanki mastyksu grysowego o zawartości destruktu do 50%. W zależności od rodzaju badanej mieszanki stosowano destrukt asfaltowy o ciągłym i nieciągłym uziarnieniu z warstw nawierzchni drogowej eksploatowanej nie dłużej niż 20 lat. Na podstawie przeprowadzonych badań stwierdzono, że dodatek destruktu asfaltowego nie powoduje utraty odporności mieszanki na dziaSłanie wody poza wartości wymagane. Stwierdzono, że niewielka ilość destruktu asfaltowego może wpływać korzystnie na poprawę wartości wskaźnika ITSR

In this paper, there are presented properties of bituminous binder modified with new generation of various n-alkane additives used in Warm Mix Asphalt (WMA) technology. Laboratory tests were focused on properties of neat bitumen blended with 18 different n-alkane additives. Based on conventional in Europe binder tests such as penetration, softening point and Fraass breaking point, consistency at service temperature was analysed. Various modifiers with different melting point temperature used in WMA technology are described together with their influence on the binder dynamic viscosity and on rheological properties such as complex modulus and phase angle. In addition dispersion of n-alkane additives in bitumen was examined based on the UV microscopy and binder morphology. It can be found that based on the comparison of the viscosity curves for neat bitumen and bitumen modified with n-alkane additives, it is possible to make first selection of the optimal additive in aspect of the WMA technology. Based on the viscosity curve analysis, for the WMA technology effective additives should present melting temperature in the range of temperature between 90 °C and 130 °C. At this temperature, n-alkane modified bitumen should be more viscosity susceptible, which mean that viscosity should faster decrease with the temperature change, as compared to the neat bitumen. Based on the rheological and morphological assessment, it can be stated that too high melting point of n-alkane additives generate some problem with additive dissolving and homogeneity of binder and does not compensate beneficial changes in bitumen rheological properties.

Bridges are an integral part of road infrastructure. In times of the roadnetwork expansion in Poland a lot of bridges were constructed. Due to the nature of work, a bridge structure should comply with specific features and requirements. This article presents the results of the fatigue life of selected asphalt mixtures used in bridge structures. Mixtures for various pavement layers were investigated. The effect of high temperature on stiffness modulus and fatigue cracking resistance with different levels of strain were analyzed. These relationships were presented in the regression equations form. The crucial influence of increased technology temperature on asphalt mix fatigue life was proved.

Durability of bridge pavement is affected by two main factors: traffic conditions and environmental factors. In Central-European climate, in addition to traffic, a bridge pavement is loaded by low temperature and deicing agents. The bridge pavement can be constructed with either cement concrete or asphalt mixture technology. In Europe (including Poland) asphalt pavements are typically placed, composed with a surface and protection layer. Pavement is placed on the waterproofing layer after initial surface priming. Both protection and surface asphalt mixtures layers can lose their properties due to aging process or due to the water action. In this paper, the results of functional properties of asphalt mixtures testing used for protection and surface layers of bridge decks are presented. Tested mixtures were subjected to short term oven aging (STOA), long term oven aging (LTOA) and aging in high technological temperatures.
