摘要
依托实际工程,对加铺层厚度进行设计计算,并采用加铺层(上面层为4 cm厚的SMA-13,下面层为6 cm厚的A-20)进行施工,为提高加铺层抗反射裂缝的能力,在试验路段加铺层添加土工布、玻纤格栅并检测其性能。研究表明,添加玻纤格栅能有效提高沥青加铺层路用性能。
In this paper,based on the actual project,the overlay thickness is designed and calculated,and the overlay layer is used in construction,the overlay layer is composed of 4cm SMA-13 upper layer and 6cm A-20 lower layer.In order to improve the anti-reflection crack ability of the overlay,geotextile and glass fiber grating were added to the overlay in the test section and their performance was tested.The research shows that adding glass fiber grating can effectively improve the pavement performance of asphalt overlay.
