1、摘要本次設(shè)計(jì)主要是泉州二級(jí)公路B段線路進(jìn)行設(shè)計(jì)，設(shè)計(jì)的內(nèi)容主要包括選線、平面設(shè)計(jì)、縱斷面設(shè)計(jì)、橫斷面設(shè)計(jì)、超高設(shè)計(jì)、擋土墻設(shè)計(jì)、瀝青混凝土路面設(shè)計(jì)。為了經(jīng)濟(jì)適用，本次設(shè)計(jì)路基寬度為14m，土路肩0.5m，為了保障排水，路面路拱度2%，土路肩為3%。路堤處設(shè)邊坡，比例1:1.5，路塹處設(shè)邊溝，邊溝坡度1:1，高度和深度均為0.5m，在深挖的路段另設(shè)截水溝截水溝，截水溝坡比、高度和深度同邊溝一致。路面采用瀝青混凝土路面，又由于該路路面等級(jí)高，所承受交通量較重，因此采用三層式結(jié)構(gòu)，即表面層采用4cm厚
