Answer to Problem 1P
Two sources of water of which highway engineer is concerned about is given below,
- Surface drainage
- Subsurface drainage
Explanation of Solution
Two sources of water of which highway engineer is concerned about is given below,
- Surface drainage
- Subsurface drainage
Surface drainage:
Generally, the main source of surface water is precipitation which is occurring from the rain and snow. From this, some of the water may get absorbed into the soil and some of it may remain on the surface. This water should be removed at the time of pavement construction. This will be the concern of a highway engineer.
Subsurface drainage:
The second source, ground water, flows into streams of underground. It may become important in cuts of highway or at places, where a high-water table exists near the structure of pavement. This source of water is known as subsurface drainage.

In order for gravel roads to have proper drainage, the highest point on the road (the crown) should slope downward on either side to the shoulders of the road. EPA guidelines for maintaining gravel roads with a low volume of traffic suggest that a 20-ft wide road should have a centerline crown that is 5 to 7 in. high.
