Publisher Comments:
Nearly all highway, airport, dock and industrial pavements contain large quantities of untreated aggregate in the form of unbound pavement layers. In many pavements, which are lightly or moderately trafficked, crushed rock or gravel derived aggregates comprise the majority of the construction or, in the case of unsealed pavements, all of the structure. This book provides studies of the performance and description of this material that will help the reader to better understand its characteristics and behavior both alone and as part of the pavement structure it forms. The contributors address modeling of the material, analysis of pavement behavior, both theoretically and in practice; measurement of properties in the laboratory and in-situ; design procedures; the influence of the environmental conditions on the material's and pavement's behavior; accelerated evaluation of performance; specification; and the opportunity for reuse of waste materials as an alternative for crushed geologic materials. Hardly any area related to this important, but poorly studied, aspect of highway engineering is omitted and the book is very useful to practitioners, policy makers, researchers, and students. It forms a sequel to the earlier book Unbound Aggregates in Road Construction.
