THE AVERAGE LIFE OF FULL-DEPTH HOT-MIX ASPHALT PAVEMENTS BUILT IN MONTGOMERY COUNTY MARYLAND 1950-1955

The results of this study indicate that the full-depth pavement being built under Montgomery County designs and receiving regular preventive maintenance, will serve satisfactorily well beyond the 24-year maximum age (1950 to 1974) observed in this study. In addition the average time to the first preventive maintenance treatment is approximately 14 years; average time between successive treatments is 10 years. These statistics are based on 123.12 miles of pavement constructed as 1,697 separate projects by several different contractors.
