摘要
聚酯玻纤布的铺设宽度对沥青加铺层的疲劳性能和工程经济性有重要影响。以沥青加铺层疲劳性能为控制指标,提出了满足加铺层疲劳性能要求的聚酯玻纤布合理铺设宽度设计方法;结合重庆成渝高速公路沥青加铺改造工程,进行聚酯玻纤布铺设宽度设计,确定了聚酯玻纤布的合理铺设宽度。
The paving width of fiberglass-polyester paving mat has great influence on fatigue performance of asphalt overlay and project efficiency. Considering the fatigue performance of asphalt overlay as the guidepost, the method of designing fiberglass-polyester paving mat with reasonable paving width is proposed to meet the needs of the fatigue performance of asphah overlay. Based on Chongqing-Chengdu Highway Asphalt Overlay Project, the design of its paving width is conducted to fix the reasonable result.
