"An increasing number of highway agencies have found that applying relatively low-cost surface preservation treatments can extend the service life of pavement. The Federal Highway Administration, American Association of State Highway and Transportation Officials, and National Cooperative Highway Research Program sponsored a scanning study of France, South Africa, and Australia to investigate innovative programs for pavement preservation. The U.S. delegation observed that the countries visited are committed to designing and building long-lasting structural pavement sections on their national roadway networks."@en . . . . . . .
