随着经济的发展,带来车辆的大型化及繁重的交通量,超载、超限车大幅度增加,对沥青路面造成车辙、疲劳等各种形式的破坏,大大缩短了路面的使用寿命,降低了路面的使用性能.尤其的气候比较炎热的南方,车辙已经成为沥青路面损害的主要形式之一,夏季温度可能高达400C以上,而沥青路面的最高温度又要比空气温度高出250C左右,路面温度可能达到600C~700C以上.为了防止车辙出现造成大面积的路面破坏,提高混合料的高温抗车辙能力具有重要意义、同时也是研究路面工程领域中的一个长期而且重要的课题.

With the development of economy, the vehicle's large and heavy traffic volume, overload and overrun a substantial increase, the asphalt pavement rutting, fatigue and other forms of damage, and greatly shortened the service life of pavement, reduce the use of pavement performance. Especialy the southern climate is hot, rut has become one of the main form of damage of asphalt pavement, the summer temperature could be as high as above 400 c, and the highest temperature asphalt roadbed than air temperature higher than 250 c, pavement temperatures may reach above 600C~ 700 C,In order to prevent the road surface rutting appear caused extensive damage, improve the mix of high-temperature anti-rutting ability is of great significance, is also a research road engineering in the field of a long and important topic.
