ABSTRACT

Concrete pavement engineering is the selection of design, materials, and construction practices to ensure satisfactory performance over the projected life of the pavement. Pavement users are sensitive to the functional performance of pavements – smoothness and skid resistance – rather than structural performance. Pavements, as a general rule, develop distresses gradually over time under traffic loading and environmental effects. An exception is when poor material choices or construction practices cause defects before or shortly after the pavement is put into service. As part of the LTPP Program, the FHWA has developed a Distress Identi-

fication Manual (Miller and Bellinger 2003). This manual provides descriptions and photographs to identify the different distress types and classify their severity. This manual lists the following distress types for JPCP and JRCP:

• Cracking – divided into corner breaks, durability (“D”) cracking, longitudinal cracking, and transverse cracking.
