Creation of Truck Weight Road Groups for Pavement Design
Weigh-in-motion (WIM) and automatic traffic recorder (ATR) devices, particularly the former, serve as indispensable sources of traffic data for mechanistic-empirical (ME) pavement design. However, the sparsely distributed WIM and ATR devices are unable to cover the entire roadway network in Indiana. The current truck weight road groups (TWRG) were developed using WIM traffic data of 20 years ago to reflect regional traffic conditions in Indiana. Because of the outdated traffic data, the existing TWRG classes fail to accurately reflect the actual traffic conditions, especially in the cases of extremely low and high truck traffic volumes. This study was performed to derive new TWRG classes using the newly collected WIM traffic data to provide accurate traffic information for pavement design. Consequently, employing the new TWRG values can significantly improve the quality of pavement design, resulting in considerable cost reduction of highway projects.
