Textbook Question
Chapter 7.1, Problem 34PE
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. (Source: http:llwaterepagov)
a. To the nearest tenth of a degree, find the angle of depression for a 5-in, centerline crown.
b. To the nearest tenth of a degree, find the angle of depression for a 7-in. centerline crown.
