GTM在高等级重交通沥青路面材料设计中的应用

Application of GTM in material designing for high grade bituminous pavement

针对目前高等级公路沥青路面早期损坏严重的现象,分析了国内现行路面材料设计方法及其不足,详细介绍了美国工程兵旋转试验机(GTM)用于高等级重交通路面材料设计的思路与方法,提出了解决重载、超载下路面材料设计的建议。

This paper analyses actual material designing methods for bituminous pavement in China,according to the serious status of bituminous pavement early corrosion.A detailed introduction is given to the way of GMT used in material designing for high grade bituminous pavement,and a suggestion is given to solve the designing problem under burden and overloading conditions.
