玻璃沥青混凝土是在普通沥青混凝土中掺入部分碎玻璃作为集料,由于碎玻璃的表面及组分特性,所制备的玻璃沥青混凝土的抗剥落性能需试验论证。本文通过比对玻璃沥青混凝土和普通沥青混凝土的马歇尔稳定度、冻融劈裂强度和动稳定度等参数,得出二者差异。试验表明,消石灰和液体抗剥落剂能有效提高玻璃沥青混凝土集料的抗剥落性能。
Glass asphalt concrete incorporates some of the broken glass as aggregate in ordinary asphalt concrete. Due to the surface and component characteristics of the broken glass, the anti-spalling performance of the glass asphalt concrete prepared needs to be demonstrated experimentally. In this paper, the differences between Marshall stability, freeze-thaw splitting strength and dynamic stability of glass asphalt concrete and common asphalt concrete are obtained. Tests show that slaked lime and liquid anti-stripping agent can effectively improve the anti-spalling performance of glass asphalt aggregate.
