Performance Tests for Hot Mix Asphalt (HMA) Including Fundamental and Empirical Procedures

This volume provides a collection of research and practical papers from an international as well as state agency research and technology activities on the use of performance tests for HMA mixture design and filed control.

The papers are arranged in four groups designed to aid the reader in locating papers of interest and to compare and contrast the range of work and opinions presented:
(1) Mixture Simulative Performance Tests – The first section relates to the practical use of some simulative loaded-wheel testers used in identifying rut-prone HMA mixtures.
(2) Mechanistic Test for Quality Control – The next grouping includes papers in that the mechanistic tests were used in field Quality Control of HMA mixtures.
(3) Mechanistic Tests for Mixture Design – This group contains several papers relating to the need for mechanistic tests in HMA mixture design.
(4) Application of New Mechanistic Test Methods in HMA Mixture Performance Evaluation – The last group of papers concerns the use of newly developed mechanistic test methods, which have potentials to be used in HMA mixture performance evaluation.

While many of the papers might have been placed in several groups, it is hoped that this organization will help the reader understand and use the technology presented and to help Committee D04 in developing the new standards and tests needed to advance the performance evaluation of HMA materials in the asphalt pavement community.

Pavements Unbound

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.

Highway and Urban Environment - Proceedings of the 8th Highway and Urban Environment Symposium

The 8th Highway and Urban Environment Symposium (8HUES) was held on 12–14 June 2006 in Nicosia, Cyprus. 8HUES was hosted in Cyprus by the Cyprus Institute. HUES is run by Chalmers University of Technology within the Alliance for Global Sustainability (AGS).

The following facts provide a background for 8HUES:
• 150 abstracts for posters and papers were accepted
• 80 delegates (24 female) attended the symposium
• 23 countries were represented, including all continents
• 71 oral presentations at the symposium
• 20 poster presentations
• 50 written manuscripts for these proceedings

HUES was initiated by Professor Ron Hamilton at Middlesex Polytechnic (now University) in the early 1980s. The initial aim was to measure and assess challenges in highway pollution. These challenges particularly included urban photochemical smog, with an emphasis on ozone formation and particle release. The first symposium was titled “Highway Pollution” and had a clear aim to make a difference. The proceedings were published in an interdisciplinary journal.
