The weight of asphalt in tons required for a paving project may be readily calculated using a few simple tools and concepts. The weight of any substance in pounds is related to its weight density or compactness. Weight density is the number of pounds of a material contained in a specific volume of the material.
Dec 28, 2000 · a hot-mix asphalt (HMA) pavement is the density of the mix that is achieved by the contractor at the time of construction. The density of a material is defined as the weight of the material, which occupies a certain volume of space. The compaction process causes the asphalt-concrete mix to be compressed and its volume reduced.
Generally, the volume is measured in cubic feet, and is calculated by multiplying the surface area by the thickness of the asphalt. The density of hot asphalt mix varies by the mix proportion and the type of aggregate material used; it is generally measured in terms of pounds per cubic foot.
Asphalt Mixtures Enter the width, length and thickness, then hit the “Calculate” button to calculate your estimate. You may also revise the default density value of 145 lbs/cubic ft. Actual densities may vary depending on the components of the mix.

How much does hot mix asphalt cost? On average, the price of the asphalt is between and 0 per ton for just the materials. The cost varies depending on the current price of oil. This Washington State Department of Transportation highway construction guide, for instance, said the average bid price in western Washington was .01 per ton.

Overview. The theoretical maximum specific gravity (Gmm) of a HMA mixture is the specific gravity excluding air voids. Thus, theoretically, if all the air voids were eliminated from an HMA sample, the combined specific gravity of the remaining aggregate and asphalt binder would be the theoretical maximum specific gravity.

Mix temperature is dependent on the grade of asphalt used in the mix: Less viscous asphalt requires lower temperatures, while more viscous asphalt requiers higher temperatures. At the start of a mix design, target temperatures are specified for proper mixing and compaction.

Asphalt density (weight of material per volume) is one of the most important parameters used in calculations to determine the quality and quantity of asphalt needed to pave roads. To calculate the weight of material needed for a project awareness of the compacted density of the material is essential 5 .

Field Investigation: Evaluation of Non-Destructive Density Testing Devices on Hot Mix Asphalt December 14, 2005 By: Jim Sawyer Doug Ledford Johnny Gilliam David Dunn Scotty Jarman North Carolina Department of Transportation
TRB’s National Cooperative Highway Research Program (NCHRP) Report 648: Mixing and Compaction Temperatures of Asphalt Binders in Hot-Mix Asphalt explores enhanced test methods for determining laboratory mixing and compaction temperatures of modified and unmodified asphalt binders.
The fine aggregate (mineral filler) is used to fill in the voids between the coarse particles, which increases the density of the asphalt concrete and provides load transfer between the larger particles. The asphalt binder is typically 5-6% of the mixture, and serves to bind the aggregates together.
