Abstract
The asphalt industry is aiming to produce high-quality materials and efficient technologies for pavement construction. One such technology that attracts attention is epoxy asphalt. This paper discussed the concepts, theories and engineering properties of epoxy asphalt technology and products. As the initial step, the chemical structure of epoxy materials was explained. Then principles of epoxy asphalt technology were discussed. Subsequently, the rheological characteristics of epoxy asphalt binder (EAB) were characterised. Engineering properties of an epoxy asphalt mixture (EAM) were then evaluated. The results indicated that EAB has better rheological properties than the traditional modified and net asphalts. Moreover, the results showed that superior structural performance of EAM compared with the traditional hot and warm mixtures. However, recyclability, initial strength and total cost of pavement construction remain matters of concern.
期刊介绍：
The international journal Road Materials and Pavement Design welcomes contributions on mechanical, thermal, chemical and/or physical properties and characteristics of bitumens, additives, bituminous mixes, asphalt concrete, cement concrete, unbound granular materials, soils, geo-composites, new and innovative materials, as well as mix design, soil stabilization, and environmental aspects of handling and re-use of road materials.
The Journal also intends to offer a platform for the publication of research of immediate interest regarding design and modeling of pavement behavior and performance, structural evaluation, stress, strain and thermal characterization and/or calculation, vehicle/road interaction, climatic effects and numerical and analytical modeling. The different layers of the road, including the soil, are considered. Emerging topics, such as new sensing methods, machine learning, smart materials and smart city pavement infrastructure are also encouraged.
Contributions in the areas of airfield pavements and rail track infrastructures as well as new emerging modes of surface transportation are also welcome.
