Durability is one important problem that pavement engineers need to address in pavement’s long service life. Furthermore, easily recycled pavement materials, and safe and efficient pavement construction are also important areas for development in road engineering. For these reasons, a new asphalt steel plastic (ASP) pavement structure was proposed with an asphalt mixture forming the surface layer, and steel plate and plastic materials functioning as the main load-bearing layers. Based on a comprehensive performance review and cost-benefit analysis, stone mastic asphalt (SMA) is recommended to be used as the surface layer; and A656 steel plate and acrylonitrile butadiene styrene (ABS) plastic materials should be the main load-bearing layer, on top of a foundation layer made with graded crushed stones. A glass fiber reinforced polymer (GFRP) insulation layer is recommended for use between the steel plate and ABS. Mechanical properties of the ASP pavement were analyzed using the finite element method. Laboratory tests were conducted to verify the thermal insulation performance of GFRP, the high-temperature stability and the fatigue resistance of ASP pavement. Results show that some of the mechanical properties of ASP pavement (with a structure of 80 mm SMA asphalt mixture, 8 mm steel plate, 140 mm ABS and 200 mm crushed stones) are comparable with conventional long-life pavement (with 350 mm asphalt layer overlaying 400 mm graded crushed stones). Dynamic stability of the ASP slab specimens can reach 10,000 times/mm, and the fatigue life is about twice that of SMA. Besides, the ASP pavement can be prefabricated and assembled on-site, and thus can greatly improve construction efficiency. From the lifecycle perspective, ASP pavement has many advantages over traditional pavements, such as durability, lower environmental footprint and recyclability, making it is worth further research.

As a renewable biomass resource, biochar is new to modify or replace asphalt binder in pavement engineering. This paper focuses on the effect of biochar on the anti-aging performance of asphalt binder. The short- and long-term aging properties of biochar modified asphalt binder were investigated using dynamic shear rheometer (DSR) and bending beam rheometer (BBR) tests. The modification mechanism was investigated through the Fourier-transform infrared spectroscopy (FTIR) test. The aging tests and viscosity analysis showed that the softening point of biochar modified asphalt binder was higher than base asphalt binder, while the aging index and aging viscosity ratio were lower than base asphalt binder. After aging, the temperature sensitivity of biochar modified asphalt binder decreased and the high-temperature stability, reflected by dynamic shear modulus and resistance to rutting, improved. The BBR test after long-term aging showed that the anti-aging performance of biochar modified asphalt binder decreased with the decrease in temperature, and control of the biochar content could ensure good low-temperature performance of the modified asphalt binder after aging. FTIR spectra analysis showed that biochar in modified asphalt binder is physically blended with asphalt binder.

High passenger and freight transport costs are a barrier to economic growth and social mobility, particularly in Low Income Countries (LICs). This paper considers the current state of knowledge regarding the barriers to achieving lower generalised transport costs. It considers both the road and railway modes across passenger and freight transport. These issues include a reform on the regulations for driver hours (preventing the road infrastructure from overloading), structuring rail concessions, increasing competition, and tackling corruption. Such reforms aim to deliver efficiency gains and service quality improvements at lower costs for users. This paper identifies the knowledge gap in previous research and concludes by setting out a research agenda that builds the evidence base for how the best practices from around the world can best be applied to the specific circumstances in Low Income Countries, with a particular focus on Sub-Saharan Africa and South Asia.

In this paper, a preliminary study is performed on the application of Class-C fly ash based geopolymer as road base material. The Class-C fly ash as a base material is collected from Manjung Coal-Fired Power Station, Lumut, Perak Malaysia. Geopolymer was produced by the reaction of fly ash with an alkaline activator (a mixture of Na2SiO3 and NaOH solutions). The effects of various NaOH concentration and fly ash/alkaline activator ratio to the strength of geopolymer paste were studied. The concentration of NaOH used in this study was 8 M, 10 M and 12 M. Various ratios of fly ash/alkaline activator (1.0, 2.0 and 3.0) and a constant ratio of Na2SiO3/NaOH at 2.5 were studied to define the maximum compressive strength. Tests were carried out on 50 × 50 × 50 mm3 cube geopolymer specimens and the test was conducted on the day-7 and day-28 for all samples. Results revealed that the 10 M NaOH concentration with the fly ash/alkaline activator of 3.0 is deduced as the optimum ratio, which exhibited the highest compressive strength at day-28 of testing.

Extensive studies on traditional and novel engineering materials and the increasing demands by growing traffic have led to tremendous changes of the function of roads. Roads, as an important part of the human living environment, have evolved from structures that were designed and built for passing vehicles, to ecological assets with significant economic importance. In addition to structural stability and durability, functions such as noise reduction, urban heat island mitigation, de-icing and exhaust gas absorption, are also expected. This study focused on state-of-the-art research on the performance, applications and challenges of six environment-friendly functional road materials, namely the permeable asphalt concrete, noise-reducing pavement materials, low heat-absorbing pavement materials, exhaust gas-decomposing pavement materials, de-icing pavement materials, and energy harvesting pavement materials. With this study, we aim to provide references to the latest relevant literatures of the design and development of environment-friendly functional pavement, and promote innovation in materials science and pavement design principles. For this purpose, this review compiled extensive knowledge in modern road construction and related disciplines, in order to promote the development of modern pavement engineering technologies.

Driving safety deteriorated dramatically on ice-covered road pavement in winter. However, it is a challenge to remove thick ice layer from the pavement surface with conventional technologies. In this study, the microwave heating performance of asphalt mixtures containing steel wool fibers was tested. Firstly, the mechanism of pavement deicing using microwave was introduced. The effect of steel wool fiber on air void content of asphalt mixture is studied, and the fiber distribution is observed. The microwave heating performance of specimens with different types and contents of steel wool were tested under the temperature of -5 °C and -10 °C. The ice-thawing time was measured and the effect of initial temperature and ice thickness on the thawing time was evaluated. Finally, the heating uniformity and sustainability aspects of this technique were assessed. Results show that the optimal steel wool fiber contents for microwave heating of asphalt mixture are 0.3% of 000#, 0.6% of 0# and 0.9%% of 2#, respectively. The ice-thawing time of the pavement with an initial temperature of -10 °C is 9.3% (000#), 11.3% (0#) and 14.8% (2#) higher than that of -5 °C. In addition, every 1cm increase in ice layer thickness requires 5.9% (000#), 7.7% (0#) and 13.0% (2#) increase in thawing time. A larger diameter of the steel wool helps to improve the heating uniformity. At last, the microwave heating capacity of specimens containing steel wool will not be significantly reduced by the repeated service in the first five winters.

Attainment of cycling comfort on urban roads encourages people to use bicycles more frequently, which has social and environmental benefits such as to improve air quality, alleviate congestion and reduce carbon emissions. Vibration is perceived by cyclists as one of the most important indicators of cycling comfort, and it greatly influences people’s choice of bicycles. However, a comprehensive correlation between cyclists' perception of comfort and cycling vibration has not yet been established in the current knowledge. In this study, a total of 46 sections of 24 urban roads (approximately 11,500m in length of asphalt pavements) in the city of Xi’an, China, were selected for field test. An innovative Dynamic Cycling Comfort (DCC) measure system consisting of an accelerometer, GPS logger and smart phone, was installed on the hand bar of a shared bicycle typically used in Xi’an, to record the dynamic data of vibration, trail, speed and mileage. Reliability of the DCC was verified, and the effect of test conditions (speed, bicycle type) on vibration evaluated. The vibration data were processed in accordance with ISO 2631 to quantitatively characterize the vibration level on each tested section. Furthermore, a total of 17 volunteers participated in this test, and the cyclists’ perception of vibration in each section was obtained via a purpose-designed questionnaire. The volunteers’ perception of environmental factors such as scenery, weather, road geometry, congestion and traffic condition were summarized to evaluate the influencing factors for cycling comfort. The thresholds of acceptable rate, comfort level and vibration perceptible level were established, based on the correlation between cycling vibration awv and subjective perception described in the questionnaire. In addition, the cycling comfort on the asphalt pavements (3,521 m) within Qujiangchi Park was mapped, to demonstrate the practical use of this study. Results showed that the DCC is able to capture the cycling data timely and accurately. K-means clustering analysis showed that the cycling vibration increases with the increase of cycling speed. Meantime, a heavier shared bicycle with solid tires results in higher cycling vibration compared with a lighter one with inflatable tires. In addition, the comfort level is proportional to acceptable rate, and inversely proportional to vibration perceptible level. The cycling comfort mapping for Qujiangchi Park proved that there is great potential to use the vibration (comfort) data to monitor pavement surface quality and for cyclists to determine their desirable cycling route. Results of this study should be interested by cyclists, bicycle manufacturers, transport planners and road authorities.

As road base materials, porous cement-stabilised aggregates (PCSA) can reduce the erosion damage caused by the water inside pavement structure. However, due to the reduced deformation resistance and anti-cracking ability associated with the high porosity, the application of PCSA has been held back. A laboratory experiment was conducted in this study to improve the cracking properties of PCSA through the incorporation of the styrene–butadiene rubber (SBR) latex. The effects of the SBR latex usage on permeability, compressive strength, flexural strength and anti-freezing ability (AFA) of PCSA were investigated. In addition, the modification mechanisms of the SBR latex on the PCSA properties were analysed. Test results indicated that the air voids and permeability coefficient decreased with the increase in the SBR latex dosages. The flexural strength and AFA were improved when the SBR latex dosages are between 10% and 15%. 7 d compressive strength has a slight decrease, while the 28 d compressive strength is increased. The significant increase in flexural strength and AFA can be attributed to the interpenetrating matrices formation, stretching effect as well as flexibility enhancement after adding the SBR latex.

In order to improve the high temperature stability and low temperature cracking resistance of asphalt mixtures, two varieties of admixtures (anti-rutting agent and lignin fiber) were selected and then combined. This is called double-mixture technology. A series of tests about pavement performance of base asphalt mixtures and asphalt mixtures with admixture of anti-rutting agent or lignin fiber were conducted. Meanwhile sensitivity analyses were used to study the influence of three factors (i.e., asphalt grade, aggregate type and gradation) on the high and low temperature performance and water stability of said asphalt mixtures. Test results indicated that the dynamic stability, residual stability, TSR and low temperature failure strain of asphalt mixtures have increased significantly with the additions of 0.40% anti-rutting agent and 0.36% lignin fiber. These results show that the high and low temperature and water stabilities of asphalt mixtures improve obviously. This supports the beneficial comprehensive effect of the double admixture. The problem of improving the asphalt mixtures performance with a single admixture is solved, in addition to also improving other pavement performance. Based on the sensitivity analysis, the most influential factors of dynamic stability, low temperature failure strain and TSR are the gradation, followed by asphalt grade and aggregate type

This study proposes an inventory analysis method to evaluate the greenhouse gas (GHG) emissions from Portland cement concrete pavement construction, based on a case project in the west of China. The concrete pavement construction process was divided into three phases, namely raw material production, concrete manufacture and pavement onsite construction. The GHG emissions of the three phases are analyzed by a life cycle inventory method. The CO2e is used to indicate the GHG emissions. The results show that for 1 km Portland cement concrete pavement construction, the total CO2e is 8215.31 tons. Based on the evaluation results, the CO2e of the raw material production phase is 7617.27 tons, accounting for 92.7% of the total GHG emissions; the CO2e of the concrete manufacture phase is 598,033.10 kg, accounting for 7.2% of the total GHG emissions. Lastly, the CO2e of the pavement onsite construction phase is 8396.59 kg, accounting for only 0.1% of the total GHG emissions. The main greenhouse gas is CO2 in each phase, which accounts for more than 98% of total emissions. N2O and CH4 emissions are relatively insignificant.

In China, the construction of asphalt pavement has a significant impact on the environment, and energy use and greenhouse gas (GHG) emissions from asphalt pavement construction have been receiving increasing attention in recent years. At present, there is no universal criterion for the evaluation of GHG emissions in asphalt pavement construction. This paper proposes to define the system boundaries for GHG emissions from asphalt pavement by using a process-based life cycle assessment method. A method for evaluating GHG emissions from asphalt pavement construction is suggested. The paper reports a case study of GHG emissions from a typical asphalt pavement construction project in China. The results show that the greenhouse gas emissions from the mixture mixing phase are the highest, and account for about 54% of the total amount. The second highest GHG emission phase is the production of raw materials. For GHG emissions of cement stabilized base/subbase, the production of raw materials emits the most, about 98%. The GHG emission for cement production alone is about 92%. The results indicate that any measures to reduce GHG emissions from asphalt pavement construction should be focused on the raw materials manufacturing stage. If the raw materials production phase is excluded, the measures to reduce GHG emissions should be aimed at the mixture mixing phase.

In this study, self-developed laboratory apparatus was devised to investigate filtration effects of permeable asphalt pavements (PAP) and their mechanisms. The filtration effect of PAP is specified by measuring 16 pollutant indices in influent and effluent samples. Results show that the PAP is highly effective in removing copper (Cu), zinc (Zn), lead (Pb) and cadmium (Cd), and relatively less effective on petroleum pollutants (PP), animal & vegetable oil (AVO), biochemical oxygen demand (BOD), chemical oxygen demand (COD) and ammonia nitrogen (NH4-N). The effect on removing total phosphorus (TP), chloride (Cl−) and total nitrogen (TN) is marginal. Influences of sampling time on pollutant concentrations were investigated as well, which indicates that the increases of sampling time reduce the pollutant concentrations to some extent. The decreases of pollution concentrations can be attributed to the interception and physisorption of porous materials used in the PAP.

This paper uses a case study of a UK inter-urban road, to explore the impact of extending the system boundary of road pavement life cycle assessment (LCA) to include increased traffic emissions due to delays during maintenance. Some previous studies have attempted this but have been limited to hypothetical scenarios or simplified traffic modelling, with no validation or sensitivity analysis. In this study, micro-simulation modelling of traffic was used to estimate emissions caused by delays at road works, for several traffic management options. The emissions were compared to those created by the maintenance operation, estimated using an LCA model. In this case study, the extra traffic emissions caused by delays at road works are relatively small, compared to those from the maintenance process, except for hydrocarbon emissions. However, they are generally close to, or above, the materiality threshold recommended in PAS2050 for estimating carbon footprints, and reach 5–10% when traffic flow levels are increased (hypothetically) or when traffic management is imposed outside times of lowest traffic flow. It is recommended, therefore, that emissions due to traffic disruption at road works should be included within the system boundary of road pavement LCA and carbon footprint studies and should be considered in developing guidelines for environmental product declarations of road pavement maintenance products and services

Efficient use of fuel and material resources, reduction in greenhouse gas emissions and control of environmental impacts have become important to the construction industry, including pavement engineering. Life cycle assessment, including carbon footprinting, is one important way of estimating the scale and environmental impacts of resource use and emissions to the environment. LCA results can be used for product development, benchmarking and policy making (e.g. investment decisions). Decision makers need to have confidence in the results of LCA studies and this will require that they are conducted in compliance with standards, in a consistent and transparent way. This chapter provides a short introduction to LCA before describing typical inputs and outputs required for pavement LCA and discussion of LCA standards as applied to road pavements. Some existing pavement LCA studies and tools are introduced and briefly reviewed. Finally, a framework for pavement LCA is suggested along with a checklist for conducting these studies and a note on challenges for developing the method in this area.

The road sector is coming under pressure to review current practice and the potential to reduce carbon emissions. The life cycle approach has been accepted as a robust method of measuring carbon footprint. Tools and data-sets have been developed to facilitate the measurement. Among them is the Calculator for Harmonised Assessment and Normalisation of Greenhouse-gas Emissions for Roads (CHANGER) developed by International Road Federation (IRF) and aimed to measure and benchmark the carbon footprint of road construction worldwide. This paper outlines the common methodology of road carbon footprinting, application of results in sustainable construction assessment schemes and resources available to undertake such analysis. Case studies of using CHANGER are provided for a UK trunk road widening, a public–private partnership highway construction in the United Arab Emirates and strategic highway upgrades in India. The CO2 output of these projects is compared, and an investigation is made to seek the causes of any differences. Finally, advice is provided on carbon measurement of roads and improvements of the IRF's tool.
