路用沥青材料的技术研究是沥青路面病害防治的关键

沥青是半刚性路面结构广泛应用的胶结材料，由于它具有良好的黏性、塑性、耐腐蚀性和憎水性，目前依然是许多国家首选的公路路面建设材料。但是，其技术成果还须不断完善和改进。就此，笔者认为：沥青路面病害的防治，关键在于技术研究的进步。

Technique Research on Asphalt Pavement Materials——The Key Preventative Measure against the Damage of Pavement

Asphalt is a cementation material that is widely used in semirigid pavement structure. Due to its nice viscidity, plasticity, corrosion resistance and hydrophobic nature, currently, as the first choice, asphalt is also adopted to roads and pavement construction materials in many countries. However, the technique results still need to improve. At this point, the author holds that the development of the technique research on asphalt pavement materials is the key preventative measure against the damage of pavement.
