Special Issue Information

Dear Colleagues,

Environmental pollution and energy consumption in the asphalt pavement construction industry have recently garnered global interest among researchers, particularly due to the decrease in resources and energy reserves. Despite its widespread use worldwide, asphalt pavement is associated with significant pollutant emissions, including Volatile Organic Compounds (VOCs) and Greenhouse Gases (GHGs). In addition, the production of asphalt pavement involves considerable consumption of fossil fuels to heat the asphalt binder and aggregate the mixture to the required temperature.

The National Asphalt Pavement Association has advocated a zero carbon emissions goal for the road industry by 2050, promoting a shift toward cleaner energy, renewable fuels, and alternative resources. The concept of sustainable asphalt pavement should be integrated into the entire process of road engineering planning, construction, operation, and maintenance. Thus, the development of sustainable asphalt pavement technologies is crucial for enhancing cost-effectiveness and minimizing environmental impact.

A series of innovative research has been carried out on hot issues such as the development of low-carbon pavement materials, sustainable pavement design theory and evaluation standards, life cycle assessments (LCAs) of asphalt pavements, the green transformation of construction equipment and technology, the efficient recycling of solid waste materials, and so on.

This Special Issue will fully demonstrate the latest original research and review results on the sustainability improvement and green low-carbon application of asphalt pavement technology and will summarize the cutting-edge dynamics and key technologies in this field, promoting sustainable and future progress in the theoretical and technological innovation of transportation infrastructure.

This research aimed to develop a comprehensive decision-making model for road rehabilitation, with the goals of extending pavement service life, minimizing major repairs, and improving the efficiency of investment and resource planning. The proposed methodology integrates structural condition, functional performance, and total economic value across the pavement lifecycle. It enables engineers and road managers to make informed decisions based on structural capacity, functional performance, asset value, and optimized rehabilitation strategies. The model was validated through case studies using data from Central European roads and accelerated pavement testing. It compared conventional and high-modulus asphalt overlays of equal thickness, demonstrating that a 3000 MPa increase in modulus extended residual life by over 30% and raised structural value by EUR 5.8/m2. This approach enhances planning and prioritization of rehabilitation activities, supports the use of higher-quality materials, reduces lifecycle costs and CO2 emissions, and facilitates integration with asset management systems. By linking pavement design, performance prediction, and asset management, the model supports strategic decision-making under performance and budget constraints. Full article
