Abstract
This design is a road design for the D3 tender section of Inner Mongolia Highway. First, the highway grade and design speed are determined based on the traffic volume and functional requirements. Then based on the geological survey and the local economic development level and other factors, the choice of route plan, and then complete the design of the road level aspect design, subgrade engineering design and pavement engineering design. In the design process, we mainly use design software such as road design software and AutoCAD.
Design results: Design of secondary road with a speed of 60km/h
This article features: The combination of weft and CAD software to complete the horizontal and horizontal design of the road, based on this and then the roadbed and road surface design.
Key Words:Highway grade; horizontal aspect design; subgrade design; pavement design
