纤维橡胶沥青封层在路面防裂中的应用

Application of Fiber Rubber Asphalt Sealing Layer in Pavement Cracking Prevention

文中以G106京广线华濮交界至被北靳寨段养护工程为例,通过对道路现状的分析,提出将玻璃纤维加入封层防治路面裂缝的技术方案。结果表明,将玻璃纤维加入封层,其制备的碎石封层抗拉强度大于温度变化引起的拉应变,能够有效解决沥青路面常规裂缝的产生,有助于改善路面的抗渗性能和平整度。

Taking the maintenance project of the G106 Beijing Guangzhou Line from the Huapu junction to Beijinzhai section as an example,through the analysis of the current situation of the road,a technical plan for adding glass fiber to the sealing layer to prevent road cracks is proposed in the article.The results indicate that adding glass fiber to the sealing layer can effectively solve the generation of conventional cracks in asphalt pavement by preparing a crushed stone sealing layer with a tensile strength greater than that caused by temperature changes,which helps to improve the impermeability and smoothness of the pavement.
