AC-13I型聚酯纤维沥青混合料的配合比设计

The Mix Proportion Design of AC-13I Asphalt Mixture with Polyester Fiber

聚酯纤维沥青混合料在潍坊市城市道路中得到广泛应用。以AC-13I型聚酯纤维沥青混合料的配合比设计为例,通过目标配合比、生产配合比及试拌试铺三个阶段,确定沥青用量范围为4.5%￣5.5%,最佳沥青用量为5.05%。最后应根据试铺段压实结果来确定。

Asphalt mixture with polyester fiber is widely used in Weifang urban roads.Taking the mix proportion design of AC-13I asphalt mixture with polyester fiber as an example, through three procedures, aim proportion, product proportion and testing to beat & lay ,the scale of asphalt quantity has been gained: 4.5%~5.5%; and the best one is 5.05%. Otherwise, the last reward should be determined by testing lay section.
