无机结合料稳定类基层沥青路面永久变形影响因素分析

Analysis of Influencing Factors on Permanent Deformation of Asphalt Pavement of Inorganic Binder Base

按照《公路沥青路面设计规范》(JTGD50—2017)提出的方法,计算和分析了基层厚度、模量以及面层模量、抗车辙能力等对无机结合料稳定类基层沥青路面永久变形量的影响,结果表明,中、上面层的抗车辙能力对永久变形量的影响最为显著。

According to the method mentioned in Specifications for Design of Highway Asphalt Pavement(JTG D50-2017),this paper calculates and analyzes the influences of base thickness,base modulus,surface modulus and surface rutting resistance on the permanent deformation of inorganic binder stabilized base asphalt pavement.The results show that the rutting resistance of middle and upper layers has the most significant effect on permanent deformation.
