Introduction

Résumé

This chapter provides an introduction to cracking in asphalt and composite pavements. This is accomplished by reviewing common types of pavement cracking as evidenced in field and accelerated pavement testing studies, reviewing existing pavement cracking models, and summarizing contemporary thinking on the mechanisms behind the various forms of pavement cracking identified. As asphalt binder or mixture is cooled, it transitions from a brittle-ductile to a quasi-brittle physical state. To complicate matters, asphalt concrete tends to become oxidized, leading to material embrittlement with time. In addition, exponentially more aging occurs near the surface of the pavement, leading to a steeply graded material system after several years in service. The amount of aging, or the aging rate, has been found to vary significantly depending upon crude source, refining techniques, additives, type and amount of recycled materials used, climate, and volumetric characteristics of the mixture. Loading time and sequence, damage, healing, complexity of interface morphology and associated mechanics, and bulk material nonlinearity are additional complicating factors that have kept asphalt pavement cracking as a vibrant, open area of research. Interface behavior such as debonding, sliding and variable contact between surfaces further complicate the behavior of pavement systems under environmental and traffic loads. This chapter is not intended to be a comprehensive review of the subject of asphalt pavement cracking; rather it provides initial motivation for the subject along with a compilation of previous works published by members of RILEM TC241-MCD and the technical committees that have preceded this committee.
