INTRODUCTION

Reflective cracks are a major concern to airport management personnel because they can significantly reduce the service life of hot mix asphalt (HMA) overlays of airside airport pavements. When HMA overlays are placed over jointed and/or severely cracked rigid and flexible pavements, the cracks and joints in the existing pavement can reflect to the surface in a short period of time. These reflective cracks have to be maintained to prevent the generation of loose aggregate and increased roughness that can be detrimental to aircraft operations. These cracks also allow water to penetrate the underlying layers causing further damage to the pavement structure.
