The following repeated loading test data are available for a 6-in. diameter by 12-in. long "crushed stone" specimen. (30 points) = a. [4 %]What are the recoverable strains obtained at the 1,000th and 80,000th load cycles? (b) [6 %] What is the resilient modulus (MR) for this crushed stone according to the behavior observed at the 1,000th and 80,000th load cycles? (c) [6 %] An Uzan (1985) type resilient modulus MR model developed for this crushed stone has the following model parameters: K1 = 8,955 psi; K2 = 0.35, K3 = 0.10. Evaluate the MR model performances at the 1,000th and 80,000th load cycles. (d) [4 %] What are the axial permanent strains (ep) at the 1,000th and 80,000th load cycles? (e) [6 %] What would be the axial permanent strain accumulated in the test sample if altogether 150,000 load cycles were applied on the specimen? (f) [4%] Based on your estimates, evaluate the rutting potential of a 24-in. thick airport pavement subbase constructed using this crushed stone material (assume similar laboratory stress states in the middle of the layer). Is this an adequate rutting performance for this airport pavement
