- Abstract:
- In order to delay or eliminate the occurrence and expansion of the reflective cracking in the asphalt concrete overlay on old cement concrete pavement, an epoxy asphalt geogrid stress-absorbing layer(EAGSAL)was designed. The EAGSAL consists of epoxy asphalt and fiberglass geogrid. The pull-out test, skew shearing test, bending beam test and fatigue test were conducted to evaluate the performance of the EAGSAL and a traditional stress-absorbing layer(TSAL). The results show that the adhesive performance, shear performance, bending strength and fatigue performance of the EAGSAL with an optimal spraying volume of epoxy asphalt are better than those of optimally designed TSAL, and the maximum bending strain of the EAGSAL is very close to that of the TSAL. The EAGSAL has superior performance in reflective cracking resistance. Moreover, the EAGSAL with the optimal spraying volume of approximately 2.0 L/m2 is thinner and lighter than the TSAL, which can decrease the thickness and improve the bearing ability of the whole pavement structure.
- 为了延缓或者消除水泥混凝土铺装上沥青混凝土加铺层的反射裂缝的出现和扩展, 设计出一种由环氧沥青和玻璃纤维土工格栅组成的环氧沥青土工格栅应力吸收层(EAGSAL).通过拉拔试验、斜剪试验、小梁弯曲试验及疲劳试验对EAGSAL和一种普通应力吸收层(TSAL)进行性能研究.结果表明:最佳环氧沥青撒布量下的EAGSAL的黏结性能、抗剪性能、抗弯强度以及疲劳性能都优于最佳设计的TSAL;EAGSAL的最大弯曲应变与TSAL非常接近;EAGSAL具有较好的抗反射裂缝能力.同时, EAGSAL的最佳环氧沥青撒布量是2.0 L/m2, 这使得EAGSAL比TSAL更轻薄, 可降低整个铺装结构的厚度, 提高铺装结构的承载能力.
