DEVELOPMENT AND IMPLEMENTATION OF A MECHANISTIC AND EMPIRICAL DESIGN GUIDE (MEPDG) FOR RIGID PAVEMENTS — PHASE 2

Abstract

The work investigates the impact of curing methods and their impact on subsequent curling in both the laboratory and the field in different drying environments. Results are also presented for a field instrumentation of a CRCP pavement in Tulsa, Oklahoma that uses a number of different curing methods. Next, a sensitivity analysis is completed for typical Oklahoma jointed and continuously reinforced pavements with different base friction parameters. Then the results from Darwin-ME are compared with field performance of CRCP and JPC pavements in Oklahoma. Finally, the shrinkage and coefficient of thermal expansion of concrete pavement mixtures are investigated with different past contents.
