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AbstractThisdesignismainlyquanzhousecondaryroadsBsectionroutesforthedesign,thedesignofcontentmainlyincludesroute,graphicdesign,alignmentdesign,cross-sectionaldesign,ultra-highdesign,retainingwalldesign,asphaltconcretepavementdesign.Inordertoeconomyapplicable,thedesignofroadbedwidthto14m,dirtroadshoulder0.5m,inordertoensuredrainage,pavingroadarchdegrees2%,dirtroadshoulderfor3%.Embankmentslope,proportionina1-1.5,cuttingplacesetditches,ditchesslope1:1,heightanddepthare0.5m,indeepdigsectionsanothersetcutditchcutditch,cutditchslope,heightanddepththanwithditchesandconsistent.Pavementusingofasphaltconcretepavement,andbecausehigh,weinheritroadlevel,sothemethodheaviertrafficinthreelayers,namely,typestructureusingintersecting4cmthickfine-grainedtypeofasphaltmixesclay,denseworthyofusing5cmthicklayerofgrainoftypeofasphaltmixesclay,densematchbynextlevel6cmthickcoarsegrainedtypedensematchsmixesclay.KeywordsQuanzhousecondaryroadsrouteselectionAsphaltmixesclay目录TOC\t"弟1,1,弟2,2,弟3,3"摘要PAGEREF_Toc295387901\hIAbstractPAGEREF_Toc295387902\hII第1章绪论PAGEREF_Toc295387903\h11.1总体设计的基本任务PAGEREF_Toc295387904\h11.2沿线自然条件PAGEREF_Toc295387905\h21.3道路建设的意义PAGEREF_Toc295387906\h2第2章公路等级PAGEREF_Toc295387907\h32.1交通分析PAGEREF_Toc295387908\h32.2主要技术指标PAGEREF_Toc295387909\h4第3章道路选线及平面设计PAGEREF_Toc295387910\h63.1选线的原则与步骤PAGEREF_Toc295387911\h63.1.1选线的原则PAGEREF_Toc295387912\h63.1.2选线的步骤PAGEREF_Toc295387913\h73.2平面线形设计PAGEREF_Toc295387914\h83.2.1直线段PAGEREF_Toc295387915\h83.2.2曲线段PAGEREF_Toc295387916\h83.3方案比选PAGEREF_Toc295387917\h14第4章纵断面设计PAGEREF_Toc295387918\h164.1纵坡设计PAGEREF_Toc295387919\h164.1.1设计要求PAGEREF_Toc2953
