Based on the chang - yu highway in julin province, this paper focus on gap - graded asphalt mixtures. aggregate grading of the gap - graded hma was designed by means of void design procedure. this paper give out a kind of new gradation of stone matrix asphalt. at the same time, this paper also studies the effect of aggregate size on road - related performance in some different gradings
本文以吉林省長余高速公路為依託，從瀝青混合料的結構形態入手，利用體積法，對骨架密實型級配類型的瀝青混合料的級配進行研究，提出新型的瀝青馬蹄脂級配，並針對不同級配的瀝青馬蹄脂碎石混合料，全面分析了粗，細集料的粒徑變化對其各種路用性能的影響。 -
