Abstract:
Since 2001, the State of Texas has been designing and constructing perpetual pavements on some of its heavily trafficked highways where the expected 20-year truck-traffic estimate of 18 kip ESALs is in excess of 30 million (TxDOT, 2001). To date, there are 10 in-service perpetual pavement (PP) sections. Based on the TxDOT initial design proposals (see Appendix A), a typical Texas PP structure consists of the following (TxDOT, 2001; Walubita et al., 2009a): -about 22 inches total thickness of hot-mix asphalt (HMA) layers; -at least 8 inches thick treated (lime or cement) base material; and -a well compacted in-situ subgrade soil material.
