摘要
根据SHRP提出的按性能分级(PG)的沥青胶结料标准规范,对用于应力吸收层的沥青进行了性能评价,结果表明所选择的沥青满足应力吸收层的要求。
In terms of SHRP, the paper advances standard specifications for asphalt binder graded following the performances, and makes performance evaluation on asphalt as stress absorption layer. Applied results have proven that selected asphalt can satisfy needs for the stress absorption.
