《公路路基设计规范》（JTG D30-2004）
《公路沥青路面设计规范》（JTG F40）
路线起讫点：本路段起点A: K0+0.00地形图坐标(34.9926，1481.7426),终点B:K4+570（149.385，1085.6193）.全长4570m。
沿线自然地理概况：该工程整个地形、地貌特征平坦，地形起伏不大，总体高差为74.7m
沿线筑路材料等建设条件：沿线地方材料有:碎石、砾石、砂、石灰、粉煤灰等。其他材料如沥青、水泥、矿粉需到外地采购.
本次设计：本项目是盐城市境内某山区主要交通干道，建成后既可缓解交通状况，开发区域经济，又可促进小型厂企的投产扩产，故而可以充分调动广大群众筑路的积极性，通过多种渠道，多形式的筹集资金，因此，为了达到方便快捷，促进经济的发展的要求，有必要，有能力在两地间修一条等级较高的公路。设计包含5个平曲线（新建公路均设绕内边线超高，半径均大于250m不设加宽），路基宽度21.5米，4个竖曲线（其中2个平包竖，2个在直线段），路面分为柔性沥青路面和刚性水泥混凝土路面两种，在K2+120至K2+220处增设挡土墙（衡重式），涵洞设置在K3+060处（盖板涵），平面交叉口设置在K0+060处（十字正交）。36410

Design overall direction
Tasks basis: According to the Shanghai Institute of Technology Urban Construction and Safety Engineering faculty Civil Engineering Traffic direction < Road survey and design task book>.
Design Standards: (1) According to the design plan requirements, the mountain road arterial highway technical standards to survey and design. Design-speed is 80 km / h, double amplitude of four-lane, 15 meters wide.
(2) Ministerial standards, specifications are: JTG B01-2003
JTG D20-2006
JTG D30-2004
JTG F40
Start and end point of the route: start point K0+000 (coordinates on topographic map 34.9926,1481.7426) end point K4+570(149.385,1085.6193). Total length of 4570m
Natural geography: The entire topography features of this project very flat. The overall dispersion is 74.7m.
Along the road construction materials and construction conditions: the local materials: gravel, sand, lime and fly ash. Other materials such as asphalt, cement and slag need to purchase.
This design: this project is a main road of the mountainous area in Yancheng territory. After the road is built, it can ease traffic situation, develop regional economy and promote the expansion of small plant enterprises. So it can fully mobilize the enthusiasm of the masses of the road, through a variety of channels, raise funds in various forms. Therefore, in order to achieve the requirements of the economic development, it is necessary to have the ability to build a higher grade highway between the two places. Design includes 5 horizontal curve (new roads are located around the inner edges of ultra high, a radius of more than 250 m not widened), roadbed width 21.5 meters, 4 vertical curve (of which two flat bag vertical and two on line segments), road asphalt flexible pavement and rigid cement concrete pavement, in to the K2+120 K2+220 installation of stop walls (Weighing), culvert set in K3+060 (Cover plate), the intersection set in the K0+060 (Decussating).
