PASER — Rating System Surface Rating Visible Distress* General Condition/ Treatment Measures 5 Fair Moderate to severe ravelling (loss of fine and coarse aggregate). Longitudinal and transverse cracks (open 1/2 ") show first signs of slight ravelling and secon- dary cracks. First signs of longitudinal cracks near pavement edge. Block cracking up to 50% of surface. Extensive to severe flushing or polishing. Some patching or edge wedging in good condition. Surface aging, sound structural condition. Needs sealcoat or nonstructural overlay. 4 Fair Severe surface ravelling. Multiple longitudinal and transverse cracking. with slight ravelling. Longitudinal cracking in wheel path. Block cracking (over 50% of surface). Patching in fair condition. Slight rutting or distortions (1/2" deep or less). Significant aging and first signs of need for strengthening. Would benefit from recycling or overlay. 3 Poor Closely spaced longitudinal and transverse cracks often showing ravelling and crack erosion. Severe block cracking. Some alligator cracking (less than 25% of surface). Patches in fair to poor condition. Moderate rutting or distortion (1" or 2" deep). Occasional potholes. Needs patching and major overlay or complete recycling. 2 Very Poor Alligator cracking (over 25% of surface). Severe distortions (over 2" deep). Extensive patching in poor condition. Potholes. Severe deterioration. Needs reconstruction with extensive base repair. 1 Failed Severe distress with extensive loss of surface integrity. Failed. Needs total reconstruction. ' Note: Individual pavements will not have all of the types of distress listed for any partintilar rating. They may have only one or two types. Page 52
