All these features must be attained with maximum economy in the cost and construction. McClure Engineering is searching for a proven Project Engineer to be a key leader on dynamic projects such as Twin Creek Master Planned Development and an expansion program with a global client…The Project Engineer (PE) is expected to be a strong promoter of McClure’s core values, vision, and mission and embody those values in all interactions with clients and team members… (a) … The legal speed is the speed at which the drivers tend to travel beyond a safe speed. Planning and Engineering Geology, Geological Society, Engineering Geology Special Publication No 4, 453–465. Geometric roadway design can be broken into three main parts: alignment, profile, and cross-section. Chongqing Traffic Planning, Survey, and Design Institute overcame challenging, mountainous terrain to design a 113-kilometer highway and cut construction time by 89 days with BIM methodology. The highest continuous speed, given that the weather conditions are conducive, to facilitate safety travelling of the vehicles is called as the design speed. Plane terrain <10%. While developing a geometrical design, it is very essential to give importance to the environmental concerns like noise and air pollution.

Access to rail systems, waterways, foreign trade zones, and highway systems have helped the state register growths of about 8% annually. Highways serve as the lifeline of a developing nation. Highway engineering is an engineering discipline branching from civil engineering that involves the planning, design, construction, operation, and maintenance of roads, bridges, and tunnels to ensure safe and effective transportation of people and goods. HIGHWAY ENGINEERING. ADVERTISEMENTS: In this article we will discuss about:- 1. Hydrological (rainfall/water table) ENGINEERING SURVEYS FOR HIGHWAY LOCATION: Raise with respect to horizontal distance is called Upward gradient (+n %) Fall with respect to Horizontal distance is called Downward Gradient (-n %) Gradient is represented as below fig: Highway Capacity Manual 2010 (HCM 2010) used PCE values and percent of heavy vehicles to account the impacts on both highway planning and operation, however, PCE values in the latest version of HCM derived based on the steady and balanced two-lane-two-way (TLTW) traffic flows. Unlike the construction of pavement, the planning process is carried out in advance. The design speed parameter affects the: Speed is a parameter that have huge variation will the person driving, the vehicle type, the topography etc. As the terrain and the gradient increases the construction cost will increase for a specific design speed. The ruling design speed on a National Highway in plain terrain as per IRC recommendations is a) 60 kmph b) 80 kmph c) 100 kmph d) 120 kmph Ans: c 19. Highway engineering.
