Volumetric Design for Hot-Mix Asphalt (HMA)
Volumetric 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

Hot Mix Asphalt | Asphalt Calculator | Calculate Aggregate ...
Overview Hot mix asphalt (HMA) pavement refers to the bound layers of a flexible pavement structure. Asphalt pavement material is a precisely engineered product composed of about 95 percent stone, sand, and gravel by weight, and about 5 percent asphalt cement, a petroleum product. Asphalt cement acts as the glue to hold the pavement together. Our HMA is mixed at our asphalt production ...

An Assessment of WSDOT’s Hot-Mix Asphalt Quality Control and ...
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 State DOT. During the last two decades, there has been a trend in the highway construction industry
HOT MIX ASPHALT WHAT IS HOT MIX ASPHALT? Hot mix asphalt may be referred to by several names. In different sections of the state it may also be referred to as bituminous concrete,hot plant mix,asphalt concrete, blacktop or Superpave. Hot mix asphalt is composed of aggregate bound together into a solid mass by asphalt cement. The aggregates total
HMA Weight-Volume Terms and Relationships. Mix design, and specifically Superpave mix design, is volumetric in nature. That is, it seeks to combine aggregate and asphalt on a volume basis (as opposed to a weight basis). Volume measurements are usually made indirectly by determining a material’s weight and specific gravity and then calculating ...
This calculator is designed to give the volume in both cubic feet and cubic yards, and the tons of asphalt hot mix required for the form size you have entered. The tonage calculation is specific to asphalt only. In our equations, 1 cubic yard of hot asphalt mix weighs 2.025 tons, or 4050 lbs.
Mar 20, 2013 · Volumetric calculations are the foundation of any good mix design. By the end of this block the student will understand: * HMA volumetric terms. * Important factors which can influence key mass-volume relationships and calculations.
SUPERPAVE VOLUMETRIC MIXTURE DESIGN AND ANALYSIS HANDBOOK
performance prediction. The system includes an asphalt binder specification, a hot-mix asphalt (HMA) design and analysis system, and computer software that integrates the system components. The Superpave binder specification and mix design system include various test equipment, test methods, and criteria. The criteria are dictated by the traffic,
VMA is the volumetric void space created by the aggregate particles in an asphalt mixture. It is filled with the volume of air voids plus the volume of the binder not absorbed into the aggregate. The mix needs a minimum VMA to have enough volume to hold the proper amount of air voids and the proper amount of binder. V mb V a VMA V be Aggregate ...

Hot Mix Asphalt (HMA) Level 2 Technician The Hot Mix Asphalt (HMA) Level 2 Job Mix Technician course is intended to cover the concepts and preparation procedures of HMA job mix formula (JMF). Individuals who complete this course will be certified to perform HMA Level 2 Job Mix Technician duties for SCDOT projects.
Simplistically, a hot-mix asphalt (HMA) material comprises three material components: • Air Voids • Mineral Aggregate • Bituminous Binder In production, the latter two materials are proportioned by mass (weight). It has long been acknowledged that the performance of HMA mixtures is more significantly influenced by the relative volumetric
