EVALUATING AND RESURFACING OLD PAVEMENTS IN VIRGINIA

WITH TRAFFIC INCREASING AT THE RATE OF ABOUT 5 PERCENT ANNUALLY ON VIRGINIA'S 50,000 MILES OF ROADS IN THE STATE HIGHWAY SYSTEM, THE MAINTENANCE FUNCTION MUST HAVE HIGH PRIORITY IF ADEQUATE SAFETY AND SERVICE ARE TO BE PROVIDED. THE ROAD SYSTEM IS EVALUATED BY HISTORICAL PERFORMANCE IN AREAS SUCH AS SAFETY, COST TO MAINTAIN, RELATION OF SERVICE TO OTHER ROADS, AVAILABLE FUNDS, AND THE MOST ECONOMICAL METHODS OF RESTORING ROADS TO ORIGINAL CONDITION. TYPES OF RESURFACING ARE BASED ON RESULTS OF EXPERIENCE GAINED BY RESEARCH AND MATERIALS USE AND BY AVAILABILITY OF MATERIALS. BECAUSE THE ROAD SYSTEM IS SO EXTENSIVE AND VARIES FROM HEAVY-VOLUME INTERSTATE ROUTES TO LIGHT-VOLUME SECONDARY ROADS, IT IS NECESSARY THAT THE APPROACH TO EVALUATING AND RESURFACING REMAIN FLEXIBLE TO TAKE ADVANTAGE OF ALL POSSIBLE ECONOMIES. THE HIGHWAY DEPARTMENT BELIEVES IT HAS DEVELOPED A SATISFACTORY METHOD OF EVALUATING AND RESTORING OLD SURFACES BY USING HISTORICAL DATA; BY USING THE JUDGMENT OF THE RESIDENT, DISTRICT, AND MAINTENANCE ENGINEERS IN EACH CASE; AND BY HAVING SPECIALISTS IN MATERIALS AND RESEARCH AVAILABLE FOR DETAILED INVESTIGATIONS IF NECESSARY. APPENDICES TREAT ORGANIZATION OF THE SYSTEM, FINANCING, STANDARD AND SPECIAL MIX SPECIFICATIONS, AND GRADATIONS AND TEST RESULTS OF DENSE GRADED AGGREGATES. /AUTHOR/
