Overlay Design Method Based on Visual Pavement Distress

Report No: 78-R26

Published in 1978

About the report:

A method for designing the thickness of overlays for bituminous concrete pavements in Virginia is described. In this method the thickness is calculated by rating the amount and severity of observed pavement distress and determining the total accumulated traffic. Ratings for the amount and severity of each type of pavement distress are tabulated in the report, and a chart for calculating the accumulated traffic from the daily traffic counts of different classifications of vehicles is given.
