摘要
本设计为河源市甲六路道路工程设计，起点为K0+000，终点为K1+730，全长1730。设计时速60km/h，城市主干道。本次设计包括横断面、平面、纵断面设计、沥青路面设计、道路排水设计、平面交叉口竖向设计、工程土方量计算等。
本设计为一条直线，起点为K0+000，终点为K1+730。纵断面设计共设5个变坡点。最大纵坡为3.2%，最小纵坡为1.4%；竖曲线半径分别有5000m、3000m、2000m。路基宽度为50m，两侧绿化带均为3m,非机动车道为8.5米，人行道总共6m，行车道横坡设为1.5%，人行道横坡设为2.0%。路面结构：4cm细粒式沥青混凝土，6cm中粒式沥青混凝土，8cm粗粒式沥青混凝土，23cm水泥稳定碎石，25cm石灰粉煤灰土。排水方面：甲六路雨水管在非机动车道上，距路中线15m，最大管径为700mm，最小管径为500mm。

Abstract
The road engineering design of Jia Liu road in HeYuan city at the point of K0+000 finishes at K1+730. The total length is 1730m. The design speed is 60km / h .It belongs to main road of a city. The design includes cross-sectional design, horizontal and vertical section design, asphalt pavement design, road drainage design, intersection design, earthwork calculation of engineering.
There are five horizontal curve in my design,it’s start at K1+000 and end at k1+730。The largest longitudinal grade is 3.2%.The smallest longitudinal grade is 1.4% . There are three styes of the radius of vertical curve ,they are 3000m ,5000m,2000m . Roadbed width is 50m. Roadbed width to 50 m, two side green belts are 6 m, non maneuvering lanes of 8.5 m, the pavement on each side for 3 m, carriageway cross-sectional slope set to 1.5%, the pavement cross-sectional slope set to 2.0%. Pavement structure: 4 cm fine grain type, 6 cm of asphalt concrete grain type asphalt concrete, 8 cm thick bead type asphalt concrete, 23 cm of the cement stable macadam, 25 cm lime fly-ash soil. About the dewatering ，the downspout of the road JiaLiu have 15m to the road central line. The biggest caliber is 700mm.The minimum caliber is 500mm.
