A RATIONAL EVALUATION OF PAVEMENT PERFORMANCE USING THE TEXAS MOBILE LOAD SIMULATOR (TXMLS)

The paper gives an overview of findings from the first three Mobile Load Simulator (MLS) test pads. Distress occurred as both rutting and cracking. However, the extent of each distress type varied between the test pads. This was unexpected since they had similar structural compositions. Changes in pavement response and material characteristics were monitored during testing using nondestructive testing (NDT). Tools used for measuring performance included a profilometer and a procedure for capturing and monitoring cracks. A diagnostic evaluation showed that the differences were probably related to varying subgrade strength and poor performance of the lime treated limestone river gravel base and the asphalt surfacing due to water ingress and aging.
