Abstract:

Currently, TxDOT uses the AASHTO 93 design guide for the slab thickness design of continuously reinforced concrete pavement (CRCP). The AASHTO 93 design guide was developed based on the AASHTO road test, where JCP (jointed plain concrete pavement) was the major pavement evaluated and CRCP was not included. From a purely technical standpoint, the AASHTO 93 design guide is not appropriate for the design of CRCP. With ever-increasing traffic on major highways in Texas where CRCP is widely used, there is a need for a more mechanistic-empirical (ME) based pavement design procedure for CRCP. An ME-based pavement design method will allow TxDOT to optimize pavement structures to best utilize the limited financial resources available. To develop an ME based CRCP design procedure, the mechanism of punchouts was identified by field evaluations of CRCP, which included coring, deflection testing using falling weight deflectometer (FWD), and other nondestructive testing.
