摘要
为了提高改性沥青应力吸收层的性能,基于不同级配特点,确定了新型橡胶沥青应力吸收层的最佳级配,提出了橡胶沥青应力吸收层混合料的技术指标,并对比研究了其高温性能和疲劳性能。结果表明:在9%的沥青用量情况下,研发的新型橡胶沥青应力吸收层具有良好的路用性能。
In order to improve the performance of modified asphalt stress absorbing layer, based on the char- acteristics of different gradations, the optimum gradation of new rubber asphalt stress absorbing layer was determined; technical indices of mixture of rubber asphalt stress absorbing layer were proposed; comparisons of high-temperature performance as well as fatigue performance were conducted. The results indicate that the newly developed rubber asphalt stress absorbing layer is of good pavement performance when the asphalt accounts for 9 percent of the mixture.
