Question

Problem 4) Using the information in your textbook (e.g., page 578) substantiate the PCA claim that the normal summer or fall k values can be used for the design purposes to avoid the tedious method of considering seasonal variations.

I can not upload another picture, please reference page 572 in Pavement Analysis and Design 2nd edition by Yang H. Huang

Answer 1

"Given that The 'k' value is obtained equation k = M_h/19.4 Therefore Then rigid foundation, no corrections are necessary. material implication Then ""k"" value be used for calculating relative damage. material implication The rigid pavement. material implication Then harm cause spring break up in April constitute only 12%. material implication The entirely harm effective modulus sub-grade response is 262 pci versus Normal value of 232 pci Therefore Means effective Modulus is superior than Normal Modulus substantiate allege \r\n of PCA material implication Then k, value will be used for both summer & spring season due to not variation."
