Research and Applications of New Pavement Structure Based on Large Stone Porous Asphalt Mixture

This paper analyzes the main reasons of premature failures of an asphalt pavement with bound base and the use of Large Stone Porous Asphalt Mixture (LSPM) to prevent such failures. A systematic evaluation of the LSPM is presented covering rutting resistance, moisture susceptibility, permeability, reflection cracking and fatigue resistance. Based on this evaluation, a new pavement structure was adopted that includes LSPM. The oldest of these sections has been in use for five years and this paper reviews the field performance.
