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 ...

 · The asphalt producer (not necessarily the contractor) will have most likely run their own Rice density, on the material you tested, which will give you the exact number you're looking for. If you have a copy of the delivery ticket, the producer's phone number should be right on there.

Cubic Yard Calculator. These calculators are designed to give approximate amounts only. They will help you determine the quantity you need; however, variations in subgrade, compaction of subgrade, or inaccurate measurements, even a quarter of an inch, can make a difference. Knowing and understanding your asphalt needs, before hiring an asphalt ...

compaction of hot mix asphalt (HMA). It may be applied to HMA having a compacted thickness of at least ft. The test method includes six parts: 1. Standardization and Calibration of the Nuclear Density Gage 2. Correlation with Core Densities 3. Selection of Test Site 4. Determination of InPlace Density with the Nuclear Density Gage 5.

Density of InPlace Hot Mix Asphalt (HMA) Pavement by Electronic Surface Contact Devices FOP for AASHTO T 343 Scope This procedure covers the inplace density determination of Hot Mix Asphalt (HMA) in accordance with AASHTO T343using an electronic surface contact device / gauge. This field operating procedure is derived from AASHTO T343.

 · How do you find the density of asphalt? Multiply the weight density of the asphalt by the volume to arrive at the weight of the asphalt needed in pounds. Consult the asphalt manufacturers if you do not know the weight density of the asphalt. In the example, use a typical weight density of 145 pounds per cubic foot.

specifiion density difference of lb per cubic ft is lower than the 6 to 7 lb per cubic ft average difference observed in this project and should provide for a significant ... HotMix Asphalt Concrete,Density, Longitudinal Construction Joint, Joint Density Keywords:

Hot Mix Asphalt weights vary based on the mix design, but 148 lbs. Per cubic foot is a good average. So, 2000 lbs divided by 148 lbs would be about cubic feet. Since 1 cubic meter equals cu. Ft.; divided by equals cubic meters

Hot mix asphalt is composed of aggregate bound together into a solid mass by asphalt cement. The aggregates total ninetythree (93) to ninetyseven (97) ... dry weight density as determined by AASHTO Designation T99 Method.) To prevent growth of weeds,the subgrade should be treated with an approved herbicide. (See NAPA

Density is achieved by compaction of the paverlaid asphaltaggregate mixture. The squeezing together of the aggregates increases their surfacetosurface contact and interparticle friction, resulting in higher stability and pavement strength. The normal target inplace density on a "dense" hotmix asphalt .

HotMix Asphalt Calculator . Instructions: 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. per cubic ft. Actual densities may vary depending on the components of the mix.

NAPA's Mission. The National Asphalt Pavement Association (NAPA) works to support, advoe, and advance the asphalt pavement industry. We support our members through eduion, technical advice, recognition programs, and peer engagement. We advoe by engaging, collaborating with, and eduing decisionmakers.

Density is achieved by compaction of the paverlaid asphaltaggregate mixture. The squeezing together of the aggregates increases their surfacetosurface contact and interparticle friction, resulting in higher stability and pavement strength. The normal target inplace density on a "dense" hotmix asphalt pavement is 92 to 93 percent of ...

As a general rule for estimating purposes, it is usually around 140 to 145 pounds per cubic foot for most of the designs I've seen in the US. The actual unit weight may vary a little. This is assumed to be compacted. You determine how much you ne...
