SERVICE LIVES OF HIGHWAY PAVEMENTS - A REAPPRAISAL

THE ANALYSES PRESENTED ARE BASED ON DATA SUBMITTED BY 19 STATES COVERING THEIR CONSTRUCTION AND RETIREMENT ACTIVITIES FROM JANUARY 1, 1929 TO JANUARY 1, 1968. BECAUSE EVERY STATE DID NOT CONSTRUCT EVERY ROADWAY-SURFACE TYPE, THE RESULTS OF SOME ANALYSES ARE FOR A COMPOSITE OF LESS THAN 19 STATES. OF THE 170,296 MILES OF HIGHWAY PAVEMENTS RETIRED, 59.3 PERCENT WAS RESURFACED, 29.5 PERCENT RECONSTRUCTED, 1.6 PERCENT ABANDONED, AND 9.6 PERCENT TRANSFERRED TO OTHER PUBLIC AUTHORITIES. ON JANUARY 1, 1968, THE AVERAGE AGE OF THE INTERMEDIATE-TYPE SURFACES WAS 15.5 YEARS, AND OF HIGH TYPES, 11.6 YEARS. CORRESPONDING REMAINING LIFE EXPECTANCIES OF THE MILEAGES IN SERVICE WERE 6.2 AND 10.9 YEARS. THE ANALYSES INDICATE THAT AVERAGE AGE AND REMAINING LIFE EXPECTANCY OF THE HIGH-TYPE SURFACE ARE STABILIZING AFTER A LONG PERIOD OF INCREASING AGE AND DECREASING REMAINING LIFE. BASED ON THE SERVICE LIVES DEVELOPED IN THIS STUDY, THE PROBABLE MILES REMAINING IN SERVICE FOR THE NEXT 10 TO 20 YEARS WERE ESTIMATED. OF THE TOTAL MILES REMAINING IN SERVICE ON JANUARY 1, 1968, IT WAS ESTIMATED THAT 60 PERCENT WILL BE RETIRED FOR DIFFERENT REASONS BY JANUARY 1, 1978, AND 87 PERCENT BY JANUARY 1, 1999. /AUTHOR/
