Abstract:Researchers analyzed all the traffic data collected by both permanent and portable weigh-in-motion stations around Texas and developed default load spectrum inputs for interstate highways, state highways, FM roads, and energy development areas. The researchers then presented the six-step pavement rehabilitation and design strategy and applied it to assist pavement designs using the Texas Flexible Pavement Design System (FPS21) combined with the latest Texas Mechanistic-Empirical Pavement Design for Flexible Pavements (TxME), as shown in Figure 1. The pavement designs of five field projects in four different districts were developed using both FPS21 and TxME and considering both field performance and initial construction cost. Furthermore, the researchers surveyed the field performance of five existing test sections with full-depth reclamation (FDR).
