Special Issue Information

Dear Colleagues,

Road engineering materials have long been an important research topic, and as such, various materials are currently used to engineer roads, including asphalt, cement, bio-based materials, nanomaterials, and waste materials, whose performance determines the level of the road’s service. The development of road engineering depends on breakthroughs in the research of these road materials. In order to build high-quality and high-level road projects, researchers aim to develop road materials that have the advantages of low cost and high performance, as well as sustainable potential. This Special Issue will provide noteworthy experimental and/or numerical investigations into or case studies on the research of road materials, including, but not limited to, the following areas of interest:

  • Preparation and characterization of road materials;
  • Molecular dynamics studies of road materials;
  • Engineering applications of road materials.
  • Asphalt materials;
  • Asphalt mixture;
  • Cement concrete;
  • Polymer materials in road engineering;
  • Waste materials in road engineering;
  • Bio-based materials in road engineering;
  • Nanomaterials in road engineering materials; etc.

In this Special Issue, original research articles and reviews are welcome.

We look forward to receiving your contributions.

Although the double-layer pavement structure with a top layer of stone mastic asphalt concrete (SMAC) and a bottom layer of epoxy asphalt concrete (EAC) has been confirmed to have excellent overall performance in the laboratory, there is a lack of comparison and verification in practical projects. Hence, the utilization of the SMAC + EAC structure in this steel bridge deck pavement (SBDP) practical project and the clarification of its service performance are of significant importance for facilitating the promotion and application of this novel structure. This study relied on an SBDP reconstruction project in Ningbo, China. Indoor performance tests were used to determine the appropriate material compositions for SMAC and EAC. Subsequently, both ERS and SMAC + EAC pavement structures were paved in the project, and the service conditions of the different pavements after one year of operation were tested and compared. The results indicated that the epoxy SBS asphalt (ESA) binder prepared by substituting SBS-modified asphalt binder for the base binder, exhibited improved mechanical strength and toughness. The variation of modifier content significantly affected the high-temperature stability, low-temperature crack resistance, and moisture damage resistance of epoxy SBS asphalt concrete (ESAC) and high-viscosity SBS asphalt concrete (HSAC), while the gradation mainly influenced the skid resistance. The optimal contents of modifiers in ESA and HAS binders were finalized at 45 wt% and 11 wt%. After one year of operation on the trial road, the pavement performance of the SMAC + EAC structure had significant advantages over the ERS system, with all lanes having an SBDP quality index (SDPQI) above 90 and an excellent service condition. The successful application of the SMAC + EAC structure validated its applicability and feasibility in SBDP, which provided strong evidence for the further promotion of this structure. Full article
