Question
Chapter 16, Problem 1P
To determine
The two sources of water of which highway engineer is concerned about.
Expert Solution & Answer
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.

CMU. The wall height is 18feet. It is assumed to be simply supported. The wall is to be designed for an out-of-plane seismicload of 52 lbs./ft.2, which can act in either direction. The wall also supports a roof dead load of600 lbs./ft. and a roof live load of 300 lbs./ft. along the wall length. The roof loads have aneccentricity of 2.5 inches. Since there is seismic load, load combinations (6) and (7) in Chapter 2of ASCE 7-22 should be considered. In these two load combinations,horizontal seismic loadhE =andvertical seismic loadvE = . You may ignorevE in this problem for simplicity. The masonryhas a specified compressive strength of 2,500 psi. (a) Use the strength design provisions of TMS402 to determine the size and spacing of the vertical bars needed. Use the P-δ analysis method inSection 9.3.4.4.2 of TMS 402 to determine Mu.
