摘 要

本项目位于河南省，主要研究洛阳至嵩山一级公路C标段施工图设计。本设计根据既定的资料，确定该公路等级为一级公路，设计速度为100 km/h。主要完成路线平面图、路线纵断面图、路基横断面图、路基排水设计图、路面结构图等的绘制及计算。

本次一级公路的平纵横设计采用纬地道路设计软件进行设计。全线长 7076.306 m，由四段直线和六段平曲线组成。本项目共设置了8个变坡点。路基宽度为24.5 m（土路肩0.75 m×2，硬路肩3 m×2，行车道3.75 m×4，左右路缘带0.5 m），双向四车道。不设超高路段的行车道及硬路肩路拱横坡采用2.0%，土路肩路拱横坡3.0%。

沥青路面结构设计采用hpds软件。路面面层采用 3 层结构，上面层采用4 cm 厚的细粒式沥青玛蹄脂碎石SMA-13，中面层采用6 cm厚的中粒式沥青混凝土AC-20C，下面层采用 8 cm 厚的粗粒式沥青混凝土AC-25F。路面基层采用40cm厚的水泥稳定碎石，底基层采用18cm厚的级配碎石。

This project is located in henan province, and mainly studies the design of construction drawing of C section of the highway in luoyang to songshan. Based on the established data, this design determines that the highway grade is a first-grade highway with a design speed of 100 km/h. It mainly completes the drawing and calculation of route plan, route profile, subgrade cross section, subgrade drainage plan, pavement structure drawing, etc.

Hint CAD are applied for road route design.The design length is 7076.306 m, consisting of four straight lines and six flat curves. The project has set up 8 slope points. The width of the roadbed is 24.5 m (soil shoulder is 0.75 m × 2, hard shoulder is 2.5 m×2, marginal strip is 0.75 m × 2, lane-width is 3.75×6 m), and the two-way four lanes. The cross slope of the carriageway and hard shoulder crown which have no ultra-high is 2.0%, and soil shoulder crown cross slope is 3.0%.

The Asphalt pavement structure layer adopts three structure, the top layer uses fine grained stone mastic asphalt SMA-13 with thickness of 4cm,the following layer adopts 6cm thick medium grained asphalt concreteAC-20C, the last layer adopts 8cm thick coarse asphalt concrete AC-25C. The base course adopts cement stabilized macadam,the last base course adopts lime fly-ash soil.

ABSTRACT

This project is located in henan province, and mainly studies the design of construction drawing of C section of the highway in luoyang to songshan. Based on the established data, this design determines that the highway grade is a first-grade highway with a design speed of 100 km/h. It mainly completes the drawing and calculation of route plan, route profile, subgrade cross section, subgrade drainage plan, pavement structure drawing, etc.

Hint CAD are applied for road route design.The design length is 7076.306 m, consisting of four straight lines and six flat curves. The project has set up 8 slope points. The width of the roadbed is 24.5 m (soil shoulder is 0.75 m × 2, hard shoulder is 2.5 m×2, marginal strip is 0.75 m × 2, lane-width is 3.75×6 m), and the two-way four lanes. The cross slope of the carriageway and hard shoulder crown which have no ultra-high is 2.0%, and soil shoulder crown cross slope is 3.0%.

HPDS pavement design software is applied for Asphalt pavement structure design. The layer adopts three structure, the top layer uses fine grained stone mastic asphalt SMA-13 with thickness of 4 cm, the following layer adopts 6 cm thick medium grained asphalt concrete AC-20C, the last layer adopts 8 cm thick coarse asphalt concrete AC-25F. The base course adopts 40 cm cement stabilized macadam, the last base course adopts 18 cm Graded crushed stone.
