Excellent No longitudinal cracks except reflection of paving joints. Recent sealcoat or new cold mix. 8 Occasional transverse cracks, widely spaced (40' or greater). Little or no maintenance Very Good All cracks sealed or tight(open less than 1/41.). required. Very slight or no raveling, surface shows some traffic wear. First signs of aging.

Individual pavements will not have all of the types of distress listed for any particular rating. They may have only one or two types.
