Answer (1 of 3): 2400kg per cubic metre is a good generic density. Sorry if you use the imperical system, I'm sure you can convert it easy enough. In real life though, it's a good idea to calibrate this figure based on tonnage used, average depth and coverage, especially if you are recieving mate...

In these areas the compaction requirements shall be 95% of the dry weight density as determined by AASHTO Designation

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.

Calculate the average density of the 3 locations and plot the average density in pounds per cubic foot versus the number of roller passes on the Asphalt Nuclear Density Thin-Lift Roller Pattern Graph, TL-57. (See pages 9-6 and 9-7 for TL forms) • Continue this procedure - rolling and testing of the section until the roller pattern reaches its ...

For example, a density reported as 94% Rice means that there are 6% air voids. The desired density is generally specified by the road owner or contracting agency. Coring to measure density Coring is a destructive testing method, which means that the cores are cut and removed from the final product – the in-place asphalt mix.

The density of asphalt mixture; Summary How to calculate the weight of asphalt. In calculating the weight of asphalt, necessary is the volume and specific gravity. It can be derived by calculating the volume from the construction area and thickness of the asphalt pavement and multiplying the specific gravity of the asphalt used for pavement.

The normal target in-place density on a "dense" hot-mix asphalt pavement is 92 to 93 percent of Gmm (or 7 to 8 percent air voids). If a pavement has low density (usually defined as less than 92 percent of Gmm), the air voids are interconnected and premature pavement distresses can result.

2. The viscosity requirement at 275° F for asphalt paving cements should be increased 50 to 60 percent over those now stipulated by the Asphalt Institute. The present and proposed limits are as follows: Penetration Grade 60-70 85-100 Stokes SSF Stokes SSF Asphalt!nstitute 2 . 4+ 120+ -1.7+ 85+ Proposed by TTI 3. 5+ 160+ 3. 0+ 13 5+

The following densities should be used for estimating quantities of Hot Mix Asphalt (HMA) material.

If the volume is unit then, Bulk Density= Mass. Unit in kg/m 3 or lb/ft 3. In this definition, the volume is that contains both the aggregates and the voids between aggregates particles. The approximate bulk density of aggregate that is commonly used in normal-weight concrete is …

Theoretical maximum specific gravity can be multiplied by the density of water (62.4 lb/ft3 or 1000 g/L) to obtain a theoretical maximum density (TMD) or "Rice" density (named after James Rice, who developed the test procedure). Theoretical maximum specific gravity is a critical HMA characteristic because it is used to calculate percent air ...

gauge to the average density determined by the 3 compaction samples. When the nuclear gauge average is greater than the compaction sample average, the correction will be subtracted and when the nuclear gauge average is less, the correction will be added to the wet density determined by the nuclear gauge.

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. Now you have 145 pounds per cubic foot times 43.7 cubic feet, which ...

However, the experimental density of Athabasca asphaltenes, in references, was found to be 1.16 g/cm 3. On the contrary, average structures density results with designated heteroatoms (Table 1) differ from 1.06 to 1.17 g/cm 3. Bigger poly-aromatic rings are present in these structures when compared with Arabian and Athabasca asphaltenes.
