Quantifying Pavement Damage in Overload Corridors

During the GAP 2019 transportation engineering conference, leading researchers from The University of Texas at El Paso (UTEP) provided a number of papers and presentations. One that drew considerable attention was "Development of a Mechanistic Approach to Quantify Pavement Damage Using Axle Load Spectra from South Texas Overload Corridors." Here, we present an abbreviated version of the paper by Ali Morovatdar, Reza S. Ashtiani, Carlos Licon, and Cesar Tirado. Their insight into the impact of overloading roadways is very interesting, especially as it indicates that this new methodology confirms that axle load equivalency factors (ALEF) values are significantly higher than those yielded through the traditional Asphalt Institute ALEF method--which is commonly used by pavement design engineers. Severe overloading could damage...
