moduli layer coefficients and drainage coefficients as shown. If the predicted ESAL
= 6x106, Reliability, R = 99%, Standard Deviation (So) = 0.45, and APSI = 2.5,
select thicknesses D1, D2, and D3 in accordance with the AASHTO Guide for
Design of Pavement Structures.

Diagramtically show the placement, size, and spacing of temperature steels, dowel bars and tie bars in rigid pavements. Also mention their puproses in rigid pavements.
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.
