通常采用沥青混合料罩面法对旧路面进行修缮,但这种方法易产生反射裂缝。本文介绍了采用沥青砂胶(FMS)作沥青混合料和旧路面间的应力吸收层的试验情况,并与使用土工布的罩面法进行了比较。另外,还计算和预测了采用FMS法的道路的使用性能和修缮费用。 Asphalt pavements are usually used to repair the old pavement, but this method is prone to reflection cracks. This paper presents a test case of using asphalt mortar (FMS) as a stress-absorbing layer between bituminous mixtures and old pavements, compared with the overlay method using geotextiles. In addition, the serviceability and repair costs of roads using the FMS method are also calculated and predicted.
