A six-lane concrete roadway is being designed for a metropolitan area. This
roadway will be constructed on a subgrade with an effective modulus of subgrade reaction k of 200 lb/in^3. The ESALs used for the design period is 6.0×10^6. Using the AASHTO design method, determine a suitable thickness of the concrete pavement (to the nearest 1/2 inch), provided that the working stress of the concrete to be used is 600 lb/in^2 and the modulus of elasticity is 6×10^6 lb/in^2. Assume the initial serviceability is 5.0 and the terminal serviceability is 2.0. Assume the overall standard deviation, So, is 0.35, the load transfer coefficient J as 3.2, the drainage coefficient, Cd, is 1.15, and R = 99%.

- 1. Plot the SWRC (suction vs. volumetric water content) from the van Genuchten (1980) model for the following “base-case” parameters (assume m = 1-1/nvG): alpha vG = 0.35 kPa-1, nvG = 2.2,Delta res = 0.02, and delta S = delta sat = 0.45. These values are approximately representative of a sand.Perform a sensitivity analysis on each of the base case parameters (i.e., vary each by ±10% while holding the other three constant) to determine their relative effects on the SWRC. For example, how would a change in s alter the curve if the other base case parameters stay the same? In your answer, provide 4 plots for the parametric evaluation of each parameter as well as a brief qualitative explanation for each plot (for example, when investigating the effect of alpha vG, show the base-case curve and the curves with different values of alpha vG on the same plot). Be sure that suction is plotted on a logarithmic scale. Also, discuss how theparameters of the van Genuchten SWRC model might differ…arrow_forwardUsing AutoCAD and exact measure that numberarrow_forwardA fully grouted reinforced masonry wall is to be constructed of 8-in. 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.
