矿物纤维沥青混合料在长陡坡路段的应用

Application of Mineral Fiber Asphalt Mixture in the Section of Long-Steep Slope Highway

介绍了矿物纤维沥青混合料在粤赣高速公路的应用情况,总结了该混合料的相关室内试验结果,采用激光横断面仪与落锤式弯沉仪(FWD)对矿物纤维试验段及其对比段进行了检测。结果表明,矿物纤维沥青混合料可提高路面面层的模量,改善沥青路面的抗车辙性能。

The application of mineral fiber asphalt mixture in the Yue-Gan expressway is introduced in this paper. The laboratory test results of the mixture are summarized. In order to obtain its application effect, the tests were conducted by laser profilometer and Falling Weight Deflectometer （FWD）. It is indicated that the moduli of mineral fiber asphalt mixture pavement is higher than common pavement, and it can enhance the rut resistance performance in the asphalt pavement.
