Structural Impacts of Non-Conventional Super Heavy Loads (SHL) on Transportation Infrastructure
Recent traffic demands and permit issuances reflect an alarming number of Super Heavy Load (SHL) applications in the energy sector and the overweight corridors of Texas. As part of project 0-6965, TxDOT developed a database of such demanding axle loads in the Eagle Ford region, and established a mechanistic framework to quantify the structural ramifications of SHLs in the overweight corridors. Some of the recorded axle weights, specifically in Farm to Market roads, are several folds of the permissible axle weight limits in Texas. The highway network in Texas is not designed to withstand such demanding loading conditions and therefore has incurred unforeseen maintenance and rehabilitation costs associated with premature failure of pavements. Therefore, it is imperative to include SHLs for the design of pavements servicing the corridors with demanding loading conditions.
