Mix Design Practices for Warm Mix Asphalt

E* - DYNAMIC MODULUS

the new 2002 Design Guide for New & Rehabilitated Pavements. The guide is based on mechanistic principles and requires a modulus, analogous to E for steel, to compute stress and strains in hot-mix asphalt (HMA) pavements. In 1999, the NCHRP Panel for Project 1-37A selected E* for this purpose. The selection was based on a paper authored by M.

Balanced Asphalt Mixture Design – National Overview

Volumetrics alone can not adequately evaluate mix variables, such as recycle, warm-mix additives, polymers, rejuvenators, and fibers. Solutions: 1. Recognize performance issues . related to dry mixes in some areas. (Note: Many performance issues are caused by factors outside the mix design.) 2. Increase understanding. of the factors which drive mix

Influence of warm MIX additives upon high rap asphalt mixes

Warm mix asphalt manufacturers have long claimed that the technologies that allow for lower production temperatures also create additional benefits when RAP is incorporated into mixtures, including the use of higher percentages of RAP without adverse effects to the mix [12,13].
