INTERSTATE HIGHWAY MAINTENANCE REQUIREMENTS AND UNIT MAINTENANCE EXPENDITURE INDEX

DATA WERE COLLECTED AND ANALYZED WITH RESEARCH AND HISTORICAL RECORDS TO ATTEMPT TO DEVELOP RELATIONSHIPS BETWEEN MAINTENANCE COST AND VARIOUS INFLUENCING FACTORS FOR THE INTERSTATE HIGHWAY SYSTEM. TWENTY-EIGHT TEST SECTIONS WERE SELECTED WITHIN NEW YORK, FLORIDA, OHIO, TEXAS, AND CALIFORNIA FOR THE INTENSIVE STUDY AND DATA COLLECTION. SIGNIFICANT VARIABLES INCLUDED IN THE TEST SECTIONS WERE TERRAIN, URBAN AND RURAL AREAS, REGIONAL CHARACTERISTICS, TRAFFIC, AND CLIMATIC CONDITIONS. DAILY REPORT DATA WERE CHECKED, SUMMARIZED, CODED AND RECORDED USING DATA PROCESSING EQUIPMENT. THIS STUDY DOES NOT INCLUDE RESURFACING OR OTHER MAJOR REHABILITATION COST. IT WAS CONCLUDED THAT THE DIFFERENCES IN MAINTENANCE STANDARDS ON THE VARIOUS TEST SECTIONS MEASURED THROUGH THE CONDITION SURVEYS WERE TOO SMALL TO AFFECT THE RELATIONSHIP DEVELOPED THROUGH REGRESSION ANALYSIS. IT WAS EVIDENT THAT EFFICIENT MAINTENANCE OPERATIONS DEPEND TO A GREAT DEGREE ON MANAGEMENT FACTORS, PARTICULARLY THE ABILITY OF FIRST-AND- SECOND-LINE SUPERVISORS RESPONSIBLE FOR THE PLANNING AND THE APPLICATION OF PROPER MIX OF MEN, EQUIPMENT, MATERIALS AND PROCEDURES TO ROUTINE TASK AND EMERGENCY REQUIREMENTS IN THE MAINTENANCE PROGRAM. GENERAL REGRESSIONAL MODELS WERE DEVELOPED FOR SEVEN DIFFERENT MAINTENANCE ACTIVITY GROUPS, PAVEMENT AND SHOULDERS, DRAINAGE AND EROSION, VEGETATION CONTROL, STRUCTURES, SNOW AND ICE CONTROL, TRAFFIC CONTROL FACILITIES AND LITTER REMOVAL AND SWEEPING. TABLES WERE DEVELOPED SHOWING THE AVERAGE DISTRIBUTION OF LABOR, EQUIPMENT AND MATERIAL BY PERCENT FOR URBAN AND RURAL AREAS FOR EACH OF THE ACTIVITY CLASSIFICATIONS TO PERMIT DIRECT CONVERSION OF THE REQUIREMENT UNITS INTO APPROPRIATE UNITS OF LABOR, EQUIPMENT AND MATERIAL. BASED ON THE USE OF THE MODELS DEVELOPED IN THIS STUDY, THE INTERSTATE SYSTEMS IS ESTIMATED TO REQUIRE THE ANNUAL EXPENDITURE OF $261,000,000 IN 1975, ASSUMING ITS FULL COMPLETION AND OPERATION BEFORE THAT DATE. PAVEMENT AND SHOULDER MAINTENANCE, CURRENTLY REPRESENTING ONLY ABOUT 15% OF THE MAINTENANCE EXPENDITURES ON THE INTERSTATE TEST SECTIONS, IS ESTIMATED TO REPRESENT ALMOST 45% OF THE TOTAL MAINTENANCE REQUIREMENTS IN 1975.
