The purpose of this final report is to evaluate the durability of Durisol noise barriers constructed in Lehigh County, Lancaster County, and Delaware County. The noise barriers constructed in each of the three counties were manufactured by one of three different fabricators. Regardless of the fabricator, the Durisol noise barriers performed less than satisfactorily at all three locations. Observations of the Durisol noise barriers since construction of the first wall in 1988 indicate barriers yield a short maintenance free service life. Repair of deteriorating and damaged panels negatively affects the aesthetic quality of the noise barrier. It is unclear how deterioration of panels affects the attenuation properties of the wall. Based on its performance, Durisol noise barrier is not recommended for any future Pennsylvania Department of Transportation projects.
