Performance-Related Specifications (PRS) are a type of construction specification that focuses on the desired long-term performance of the pavement, rather than simply specifying the materials and methods used to build it. They directly link payment to the predicted performance of the pavement, incentivizing contractors to build high-quality pavements that will last longer. PRS typically include performance indicators that are directly related to pavement performance, such as smoothness (measured by IRI), rutting resistance, cracking resistance, and durability. These indicators are measured during and after constructi....
