In the past 3 years, the institute for transportation research and education (ITRE) has developed and implemented pavement/management systems for more than 80 municipalities in north carolina. This represents more than one-half of the total municipal street mileage in the state. In spring 1983, ITRE modified the pavement condition survey for asphalt pavement that it developed for the north carolina department of transportation. Eight pavement distresses are identified and quantified. They are alligator cracking, block/transverse cracking, reflective cracking, rutting, raveling, bleeding, ride quality, and patching. The street system is also completely inventoried. ITRE developed the pavement management system software to analyse survey data. Results are calculated using maintenance levels of service and costs that can easily be changed by the user. Management reports available are alphabetical listing, priority listing, and maintenance summary tables. Calculated for each section is an estimated number of square yards of full-depth patching required, pavement condition rating (PCR), estimated maintenance cost and recommended maintenance activity. Results have been used as justification for street maintenance budget increases and resurfacing priorities.
