Information on the two main materials that are used to build an asphalt pavement, the asphalt binder and aggregate are found in Chapter 3. Regarding the binder, significant discussion is made of a binders unique characteristics at both high and low temperatures and how they change with time as the material AP42 Section:11.1 Of The Use Of Recycled Paving (1-2) and (3-4). Chapter 2 is further subdivided between FHWA's assessment of engineering and EPA's assessment . of . human health and the environment. Both assessments address their respective technical issues as they relate to asphalt pavement containing recycled rubber and to the recycling . of . those pavements. Chaprer 3 is subdi- vided by the three specific materials identified in sec-

An Assessment of WSDOTs Hot-Mix Asphalt Quality

Hot Mix Asphalt (HMA) is the major paving material for WSDOT which purchased almost 1.5 million tons per year over a five year period (from 2002 through 2006 (WSDOT, 2006a)). How the quality of this material is assured is a critical issue for any Chapter 2 is a literature review and assessment. It largely draws on national and local Asphalt Pavements - an overview ScienceDirect TopicsJames G. Speight PhD, DSC, in Asphalt Materials Science and Technology, 2016 8.2.6 Porous Asphalt. Porous asphalt pavements offer developers a new option for managing storm water. Porous asphalt pavements, used mostly for parking lots, allow water to drain through the pavement surface into a stone recharge bed and infiltrate into the soils below the pavement.

Asphalt-Rubber Standard Practice Guide

Dec 21, 2011 · Asphalt-rubber is a mixture of hot asphalt binder and crumb rubber manufactured from scrap or waste tires. Asphalt-rubber contains visible particles of scrap tire rubber. This guide focuses on asphalt-rubber as defined by the American Society of Testing and Materials (ASTM) D-8. Biobased Epoxy Asphalt Binder (BEAB) for Pavement Mar 10, 2018 · These concerns have led to substituting petroleum-based paving materials with their biobased counterparts. Research efforts have attempted to produce asphalt from renewable bio-resources. As a special modifier for asphalt, petroleum-based epoxy resin has been used in a few asphalt paving projects that require superior performance of asphalt

In asphalt paving, an asphalt distributor (also called pressure distributor) is used to apply the tack coat. Tack is a bonding agent used to bond two layers together. The asphalt distributor is an insulated tank, equipped with a heat-ing system, and designed to spray asphalt while mounted on pneumatic tires wide enough not to damage the roads EVALUATION OF INTELLIGENT COMPACTION IN CHAPTER 2 LITERATURE REVIEW 2.1 Background Compaction is one of the key processes to acquire a desired long-term pavement performance, especially for asphalt mixture layers, including hot-mix asphalt (HMA) and warm-mix asphalt (WMA).

SHRP-A-650 Summary of Health Practices:The Use of Petroleum Asphalt in the Hot-Mix Paving Industry R. Marcus Barksdale, M.S. James Scherocman, P.E. The Effect of Voids in Mineral Aggregate (VMA) on Hot 1. The void content is high allowing air and water to prematurely harden the asphalt. 2. The asphalt and aggregate are not chemically compatible, making it easier to "strip" the asphalt from the aggregate. 3. The asphalt film thickness is not sufficient to protect the mix from the abrasive action of tires and water.
