• Resumen

  • This paper analyzes the main reasons of premature failures of 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.
