摘要

本次设计主要是泉州二级公路b段线路进行设计，设计的内容主要包括选线、平面设计、纵断面设计、横断面设计、超高设计、挡土墙设计、沥青混凝土路面设计。

为了经济适用，本次设计路基宽度为14m，土路肩0.5m，为了保障排水，路面路拱度2%，土路肩为3%。

路堤处设边坡，比例1:

1.5，路堑处设边沟，边沟坡度1:

1，高度和深度均为0.5m，在深挖的路段另设截水沟截水沟，截水沟坡比、高度和深度同边沟一致。

路面采用沥青混凝土路面，又由于该路路面等级高，所承受交通量较重，因此采用三层式结构，即表面层采用4cm厚的细粒式密集配沥青混泥土，中面层采用5cm厚中粒式密集配沥青混泥土，下层面采用6cm厚粗粒式密集配混泥土。

关键词泉州二级公路选线沥青混泥土
