摘要
从沥青面层的作用和品质要求出发 ,结合山西特点 ,对传统 AC型、AK( SAC)型、SMA面层结构做分析对比 ,提出沥青面层结构组合要坚持三个前提条件 ,采用三层式 型级配 ,抗滑表层和改性沥青 ,将透层改为下封层等 ,使面层抗滑、密水、耐久、抗开裂、抗车辙。
From the requirement of action and quality of bituminous surface,combined with Shanxi characteristics,the structure of traditional AC,AK(SAC),SMA surface is analysed by contrast.Relative conditions of bituminous surface structure combination are given so as to make surface with the characteristics of skid,crack,rut resistance and durability etc.
