橡胶沥青因其优异性能已在道路工程中得到广泛应用。本文以昆明市兴苑路采用的橡胶沥青混凝土以及一环路采用SBS改性沥青混凝土为样本,通过实测橡胶沥青混凝土及橡胶应力吸收层在道路路面应用中的相关物理力学性能(抗老化性、弹性恢复性、高温稳定性等),并与在同条件下实测的SBS改性沥青混凝土对应的相关物理力学性能进行比较,体现出橡胶沥青混凝土的优越性能,得出橡胶沥青在城市道路中应用的可行性的结论,并为其在昆明市城市道路中推广应用提供参考依据。
Rubber asphalt has been widely used in road engineering because of its excellent performance. In this paper, the rubber asphalt concrete used in Xingyuan Road, Kunming City, and the first ring road are made of SBS modified asphalt concrete. The physical and mechanical properties of asphalt concrete and rubber stress absorption layer in road pavement are measured (anti-aging, Elastic recovery, high temperature stability, etc.), and compared with the corresponding physical and mechanical properties of SBS modified asphalt concrete measured under the same conditions to reflect the superior performance of rubber asphalt concrete, obtained rubber asphalt application in urban roads The conclusion of feasibility and provide reference for its popularization and application in urban road of Kunming.
