掺加纤维增强沥青混凝土高温性能试验研究

High-Temperature Tests of Asphalt Cement Adding Fiber Reinforced

沥青混合料通常用于铺筑路面的面层,直接承受车辆荷载的反复作用和各种大气自然因素的长期作用。为了能使路面为交通车辆提供安全、舒适、稳定、耐久的服务,沥青混合料必须具有高温稳定性、低温抗裂性、耐久性、抗滑性及施工和易性。鉴于此,通过对7种沥青混合料的高温稳定性试验,对比分析不同纤维对沥青混合料路用性能的影响,可为相关工程提供参考和借鉴。

The asphalt cement mixture is usually used for paving the surface layer, directly under the long term effects of repeated vehicle loads and a variety of atmospheric natural factors. In order to make road pave ment provide a kind of safe, comfortable, stable and durable serve to transport vehicles, asphalt mixture must have high temperature stability, low temperature performance, durability, slip resistance and workability. Given this, the paper proposes the high temperature stability test of seven kinds of asphalt mixture, and comparatively analyzes the influence of different fibers on the pavement performance of asphalt mixture. It can provide reference for peers.
