广西不同岩性细集料SMA-13沥青混合料的性能对比分析

Comparative Analysis of Performance of Different Lithological Fine Aggregate SMA-13 Asphalt Mixtures in Guangxi

文章依托某高速公路,针对近几年广西高速公路在进行上面层SMA-13沥青混合料细集料机制砂选择过程中存在的片面认识,对不同岩性细集料机制砂设计的SMA-13沥青混合料性能进行对比研究,对比分析级配、油石比、析漏、飞散、水稳定性能、高温稳定性能以及路用抗滑性能等指标,为广西高速公路上面层SMA-13沥青混合料细集料机制砂多元化的选择提供参考。

Based on a certain expressway,and regarding the unilateral understanding about the fine aggregate machine-made sand selection process of upper-layer SMA-13 asphalt mixture for Guangxi expressways in recent years,this article conducts the performance comparison study of SMA-13 asphalt mixture designed by different lithological fine aggregate machine-made sand,and compares and analyzes the gradation,oil-stone ratio,leak,scattering,water stability,high-temperature stability and road anti-sliding performance indicators,thus providing the reference for the diversified selection of fine aggregate machine-made sand of upper-layer SMA-13 asphalt mixture in Guangxi expressway.
