With growing municipal roadway networks, reduced budgets and higher expectations, the need for many agencies to efficiently and cost-effectively monitor and maintain pavement assets presents a monumental challenge.

The ultimate goal of any agency is to meet the public’s expectations by providing an acceptable level of service while optimizing existing budgets. For pavement preservation, the three key factor for success is determining the right treatment, for the right pavement, at the right time.

The City of San Antonio, Texas, recently completed a three-year project that included pavement distress and ride condition surveys, ground penetrating radar testing, and asset inventory of several roadside assets on approximately 4,000 centerline miles. The ability to collect these data in a single collection pass provides a cost-effective option for obtaining information to support several departments within an agency.

“The pavement evaluation process for San Antonio is the most important tool that is utilized to assess, plan, and ultimately maintain the city’s infrastructure,” said Richard E. Martinez, operations manager, San Antonio Department of Public Works.

“Funding limitations mandate a very comprehensive evaluation in order to ensure the limited dollars are dedicated to the most effective maintenance applications,” Martinez said. “San Antonio not only invests in rehabilitative applications but has allocated a signifi cant amount of resources towards pavement preservation. In 2012 San Antonio began an in-house slurry seal program, which will expand in 2013. This will assist the Public Works Department in effectively monitoring and managing the performance of pavement infrastructure within the City of San Antonio.”
