Pavement Forensics

Despite advancements in pavement design and construction technology, premature failures and chronic pavement distresses continue to occur. Forensic investigations of pavements are generally conducted to
 
(1) investigate underlying causes of premature pavement failures;
 
(2) understand the factors contributing to exceptional pavement performance and longevity; and (3) collect data to support the development and/or calibration of performance prediction models. These causes have to be recognized to prevent and reduce the possibility of premature pavement failures and poor pavement performance. CEC has the background and expertise to identify the causes of early pavement deterioration including how to develop a sound pavement preservation plan.
 
To conduct a pavement forensic study; first, review existing quality construction records and tests; and second, conduct nondestructive tests such as ground penetrating radar (GPR) and/or falling weight deflectometer (FWD) to identify causes of failure. To confirm the results of the nondestructive testing and if necessary, field testing such as Dynamic Cone Penetrometer (DCP), coring, trenching, and laboratory testing may be considered.
