为提高沥青路面行车抗滑耐久性能,研究开发了一种新型的高粘度抗滑封装薄层材料。通过理论分析及室内肯塔堡飞散试验、抗折抗压强度试验、粘附力试验、干缩试验、静态模量试验及小型加载试验开展研究。结果表明:开发的高粘度抗滑封装薄层的弯拉强度标准值大于5.0MPa,满足重载交通要求;与沥青路面具有很好的粘结力,斜剪试验28 d剪应力可达到0.89 MPa,是沥青路面抗剪要求的1.8倍;-10℃、15℃和60℃三个试验温度下28 d静态模量测定值均在8 000 MPa左右,能够抵抗车辆车载及温度应力作用;对于室内小型加速加载试验测试,经过18万次荷载作用,摆值仍能够达到51BPN,远高于规范要求的42BPN。开发的高粘度抗...

In order to improve the long-term performance of asphalt pavement against sliding,a new kind of high viscosity anti-sliding encapsulating thin layer material was developed.Through theoretical analysis and indoor Kentucky dispersion test,flexural and compressive strength test,adhesion test,static modulus test and small load test.The results show that the developed high viscosity anti-slip packaging thin layer has a flexural and tensile strength standard value greater than 5.0 MPa,which meets the requirements of heavy traffic.It has good adhesion...
