Book Description

This report describes CTR Study 1246, which proved to be very dynamic, in that the initial objectives were not only met, but they were followed up by new objectives. This was due to decisions taken by the project steering committee during the execution of the project. Following initial exploratory studies in 1988, the Texas SDHPT initiated the present study through which a strategy for the acquisition of a mobile accelerated pavement testing device had to be developed. Initially, the study focussed on the feasibility of accelerated testing and the need for it in Texas. As part of the initial study, the relationship of accelerated testing to overall pavement engineering was reviewed in detail. Once the feasibility had been illustrated, the objectives were redirected to the acquisition of a mobile accelerated pavement device. The different available methods and machines were evaluated, and subsequently the Mobile Load Simulator (MLS) was selected for future application on pavements in the state of Texas.
