开级配大粒径沥青混合料LSPAM的路用性能分析

The Road Performance Analysis of Open-graded Large-stone Asphalt Mixture

根据开级配大粒径沥青混合料LSPAM其骨架空隙结构的特性,通过对LSPAM-25、ATPB-25两种沥青混合料在路用性能进行分析,试验结果表明LSPAM具有更好的高温性能、水稳定性和耐久性,但必须采用黏结力足够高的沥青胶结料才能发挥结构整体抗力。

By determining the mechanical properties of concrete, the paper discussed the influence of slag fineness and content to concrete structure for improving concrete quality.
