wisconsindot.govasphaltic binder. Design mixtures conforming to table 460-1 and table 460-2. (2) Determine the target JMF asphalt binder content for production from the mix design data corresponding to 3.0 percent air voids (97 percent Gmm) target at the design number of gyrations (Ndes). Add liquid asphalt to achieve the required air voids at Ndes.
Volumetric Design for Hot-Mix Asphalt (HMA)
www.wsdot.wa.govVolumetric Design for Hot-Mix Asphalt (HMA) 1. Scope . 1.1 This standard for mix design evaluation uses aggregate and mixture properties to produce a hot-mix asphalt (HMA) job-mix formula. The mix design is based on the volumetric properties of the HMA in terms of the air voids (V ), voids in the mineral aggregate (VMA), and voids . a

The absorptiveness (ability to absorb asphalt) of the aggregate used in the mix is critical in determining optimum asphalt content. Enough asphalt must be added to the mix to allow for absorption and still coat the particles with an adequate film.

Soil Cement Stabilization - Mix Design, Control and ...
www.ecslimited.comSoil-cement mixes were prepared with varying cement contents ranging from 4% to 6% by weight. The mix design requirement was to establish the cement content necessary to have a minimum unconfined compressive strength of 250 psi (1724 kpa) at 7 days. This paper presents the soil-cement mix design, field-laboratory procedure and results.
