Download or read book Performance Survey on Open-graded Friction Course Mixes written by Gerald Huber. This book was released on 2000. Available in PDF, EPUB and Kindle. Book excerpt: This synthesis will be of interest to pavement construction, maintenance, design, and materials engineers; pavement contractors; and others interested in the use of open-graded friction course (OGFC) mixes. It describes the current state of the practice on the use of OGFC mixes, including information regarding design, materials, construction, maintenance, and rehabilitation strategies. Alternative treatments to traditional OGFC are also identified and discussed. Information was collected by surveying U.S. and Canadian transportation agencies and by conducting a literature search to gather additional insight into North American and European practices. This TRB report describes the recent performance of North American OGFC mixes and European porous asphalt by identifying benefits and stress indicators. A new generation of OGFC mixes has evolved over the last 5 years with changes that have been reported to dramatically improve performance. This synthesis describes new materials and design methods being used, as well as the applicability of the new generation of open-graded mixtures to North American use.

Book excerpt: The overall objective of this study was to assess the use of locally available materials in Nevada for the development of a durable fine-graded thin hot-mix asphalt overlay mixture for pavement preservation. A comprehensive laboratory evaluation using typical materials in Nevada was conducted. The investigation considered establishing two mix designs using typical local materials for the northern and southern part of the state. An optimal asphalt binder content was selected for each mixture based on the volumetric properties and following the Nevada Department of Transportation volumetric requirements. For each mixture, the optimal binder content was varied within the allowable tolerances to simulate the potential variation in asphalt binder content during plant production. The performance of the two thin hot-mix asphalt mixtures were then evaluated at the various asphalt binder contents in terms of their resistance to moisture damage using indirect tensile strength, resistance to surface raveling and abrasion, dynamic modulus property, resistance to rutting, resistance to reflective cracking, workability and compactability, and the developed interlayer bond strength. Overall, both designed fine-graded mixtures showed a very good performance and are expected perform well when used as a thin hot-mix asphalt overlay. In particular, good stability, very good resistance to surface raveling and abrasion, and excellent resistance to reflective cracking were observed for both thin hot-mix asphalt overlay mixtures at all evaluated asphalt binder contents. Thin asphalt overlay mixtures behaved as ordinary mixture and are expected to last longer than chip seals for a lower net present worth costs.

Book Synopsis Advances in Asphalt Materials by : Shin-Che Huang

Download or read book Advances in Asphalt Materials written by Shin-Che Huang. This book was released on 2015-04-08. Available in PDF, EPUB and Kindle. Book excerpt: The urgent need for infrastructure rehabilitation and maintenance has led to a rise in the levels of research into bituminous materials. Breakthroughs in sustainable and environmentally friendly bituminous materials are certain to have a significant impact on national economies and energy sustainability. This book will provide a comprehensive review on recent advances in research and technological developments in bituminous materials. Opening with an introductory chapter on asphalt materials and a section on the perspective of bituminous binder specifications, Part One covers the physiochemical characterisation and analysis of asphalt materials. Part Two reviews the range of distress (damage) mechanisms in asphalt materials, with chapters covering cracking, deformation, fatigue cracking and healing of asphalt mixtures, as well as moisture damage and the multiscale oxidative aging modelling approach for asphalt concrete. The final section of this book investigates alternative asphalt materials. Chapters within this section review such aspects as alternative binders for asphalt pavements such as bio binders and RAP, paving with asphalt emulsions and aggregate grading optimization. Provides an insight into advances and techniques for bituminous materials Comprehensively reviews the physicochemical characteristics of bituminous materials Investigate asphalt materials on the nano-scale, including how RAP/RAS materials can be recycled and how asphalt materials can self-heal and rejuvenator selection
