CONDITION SURVEYS IN THE STRATEGIC HIGHWAY RESEARCH PROGRAM LONG-TERM PAVEMENT PERFORMANCE STUDY AND PAVEMENT CONDITION RATING FOR PREOVERLAY CONDITIONS (ABRIDGMENT)

The long-term pavement performance (LTPP) research study, a component of the Strategic Highway Research Program (SHRP), represents a $50 million effort to collect field observations of pavement structures from across the United States and Canada. The procedures to be used for rating the condition of LTPP test sections before overlay are discussed. The methods should be used in classifying the condition of a test section as "good" or "bad"; such information is needed as an input variable to the asphalt concrete overlays on asphalt and concrete pavement factorial experiments. These experiments were defined for recruiting in-service test sections for inclusion in the SHRP LTPP study. The distress-monitoring approach being adopted for the long-term monitoring of in-service SHRP pavement sections is then described. The categories and types of distress data to be collected periodically are described, together with uniform and practical distress definitions and monitoring procedures. Finally, information on the contents of survey forms and maps to be used during the process is provided.
