Evaluation of crack relief layer for airport runways

This paper investigates some observations that have been made in a number of countries around the world on the behavior and function of crack relief layer (CRL). Throughout the years, crack in pavement is a major problem that causes an obstruction to transportation system which has cost multi-millio...
