Hot Mix Asphalts 101

Asphalt Rubber Applications • Asphalt rubber is the process of adding recycled, crumb rubber to hot mix asphalt (called dry process) or the asphalt binder (called wet process) to modify the final mixture • Difficult to use in dense graded mixtures due to residual crumb rubber • Best used in gap graded type mixtures (SMA and OGFC).

Pavement Design

Pavement Design Highway users have an increased awareness of pavement quality To help agencies and contractors meet the demand for high quality pavements, NAPA's Asphalt Pavement magazine regularly provides articles that directly address issues such as mix type selection and statistical specifications PaveXpress is a free, Web based tool for the structural design of flexible and rigid.

GUIDANCE NOTES ON MIX DESIGN OF BITUMINOUSTHE PROCEDURE FOR THE DESIGN OF BITUMINOUS MATERIALS Foreword 1 Scope This document describes the procedure for designing bituminous materials in accordance with the Marshall Method of Mix Design stated in the Asphalt Institute Handbook "MS 2 Mix Design for Asphalt Concrete and other Hot mix Types,"1984 Edition, with modifications.Marshall Mix DesignMix Design Methods for Asphalt, 6th ed, MS 02 Asphalt Institute Lexington, KY Marshall Method History (from White, 1985 [1]) During World War II, the US Army Corps of Engineers (USCOE) began evaluating various HMA mix design methods for use in airfield pavement design Motivation for this search came from the ever increasing wheel loads.WebinarsThe best way to register for webinars is online using the Asphalt Institute’s secure webinar website For any questions, send an email to [email protected] Important Announcement from CISCO WebEx (Please read before registering for live or recorded webinars); Scheduled Live Sessions ($85) Every live session will be recorded and available as a recording after the live webinar is.Chapter 1TRB’s National Cooperative Highway Research Program (NCHRP) Report 673 A Manual for Design of Hot Mix Asphalt with Commentary incorporates the many advances in materials characterization and hot mix asphalt (HMA) mix design technology developed since the conclusion of the Strategic Highway Research Program (SHRP).An Introduction to Asphalt EmulsionsAsphalt cement is the basic ingredient of asphalt emulsions In most cases, it makes up from 50 to 75 percent of the emulsion Some properties of the asphalt significantly affect the finished emulsion But there is not an exact correlation between the properties and the ability to emulsify the asphalt.TDOTIntroduction •Name •Company •Experience Who Are YOU?
