沥青路面过早出现病害是由于路面的耐久性不足所造成。为了提高路面的使用寿命,寻找一种新型的沥青改性材料来提高沥青路面的路用性能,本文采用国内生产的天然沥青来对基质沥青进行改性,经试验后结果表明,该种改性沥青的水稳定性和高温稳定性特别优良,但抗疲劳性能比较差,需添加外掺剂来提高其抗疲劳性能,从而提高道路使用寿命。 Premature failure of asphalt pavement is caused by the lack of durability of the pavement. In order to improve the service life of the pavement and to find a new type of asphalt modified material to improve the pavement performance of asphalt pavement, the domestic asphalt produced by this method is used to modify the matrix asphalt. After the test results show that this kind of modification Asphalt has excellent water stability and high temperature stability, but its anti-fatigue performance is relatively poor. It is necessary to add external admixture to improve its anti-fatigue performance so as to improve road life.
