1 配合比调整设定高速公路A段路面工程中 ,沥青混凝土设计分别为下面层AC - 2 5 (II)型、中面层AC - 2 0 (I)型及AK - 1 6A型抗滑表面 ,其设计厚度分别为6cm、5cm和 4cm。由于表面仅 4cm ,沥青混凝土中集料级配组合非常重要。根据以往施工经验 ,集料最大粒径与铺筑厚度比为 1
1 Mixing Adjustment Setting Asphalt Concrete Design for the A Section of Highway Engineering, the design of AC - 2 5 (II), AC - 2 0 (I) and AK - 1 6A sliding surface , The design thickness of 6cm, 5cm and 4cm respectively. As the surface is only 4cm, asphalt aggregate aggregate gradation is very important. According to the past construction experience, the largest aggregate size and paved thickness ratio of 1
