relative density of asphalt

METHOD OF TEST FOR THEORETICAL MAXIMUM RELATIVE …

of the asphalt cement. See Figure 1 for details. Note 8: While the determination of maximum theoretical relative density can be done for any asphalt cement content, the precision of the test is best when the mixture is close to the design asphalt content. Also, the test shall be done in duplicate or triplicate. 6. PREPARATION FROM LOOSE FIELD ...

Compaction of Hot Mix Asphalt Concrete

The terms "relative density" and "relative compaction" are often used to mean the same thing. In either case the "relative" refers to the ratio of field density to either laboratory maximum density or to theoretical maximum density or density of the voidless mass.

Asphalt Mixture Theoretical Maximum Relative Density of ...

Abstract: Through comparing and anglicizing several methods of measuring maximum theoretical relative density of asphalt mixture determine that regardless of the ordinary or modified bitumen, aggregate and effective use of the relative density of the most reasonable method of calculation, but the actual measurement method would be very good method if applied properly.

Density of Concrete, Asphalt in 285 units of density

Concrete, Asphalt weighs 2.243 gram per cubic centimeter or 2 243 kilogram per cubic meter, i.e. density of concrete, Asphalt is equal to 2 243 kg/m³. In Imperial or US customary measurement system, the density is equal to 140.0259 pound per cubic foot [lb/ft³], or 1.2965 ounce per cubic inch [oz/inch³] .

Estimation of density and moisture content in asphalt ...

More specifically, the density or gravimetric moisture content can be expressed as a function of the volumetric concentrations and relative permittivities of the mixture's components (asphalt binder, aggregates, voids within air or water),, .

METHOD OF TEST FOR BULK RELATIVE DENSITY OF …

1.1 This method covers the procedure for the determination of the bulk relative density of compacted bituminous mixtures with air voids of approximately 10% and greater or for bituminous mixtures with absorptions greater than 2%. 2.

Relative density of asphalt | Density | Nature

Relative Density of Solid Pitch and Asphalt (Displacement Method)1 This standard is issued under the xed designation D71; the number immediately following the designation indicates the year of original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval.

DENSITY OF ASPHALT CONCRETE - HOW MUCH IS NEEDED?

asphalt mixtures.A mixture that is properly designed and compacted will contain enough air voids to prevent rutting due to plastic flow but low enough air voids to prevent permeability of air and water. Since density of an asphalt mixture varies throughout its life the voids must be low enough

Measuring the density of bitumen/asphalt :: Anton Paar Wiki

The density of bitumen/asphalt is typically given in kg/cm 3. If API numbers or the relative density are required, this needs to be calculated (manually in the case of pycnometers or automatically by the density meter, if used).

DETERMINING THE IN-PLACE DENSITY AND RELATIVE …

the average in-place density and relative compaction of asphalt concrete (AC). It may be applied to AC which has a compacted thickness of at least 30 mm. All test data and related information is recorded on Form TL-3112. This test method is divided into the following parts:

ASPHALT CONCRETE PAVEMENT - lhcaz.gov

1. Relative Density Relative density is determined by the bulk specific gravity of the compacted pavement divided by the 75 blow Marshall specific gravity of the corresponding lot. 2. Lot For the purposes of compliance testing, a lot shall be 300 tons of asphalt concrete placed or one day's production, as determined by the Engineer. 3.

How much does density matter? | Asphalt magazine

The design was optimized at 5.4 percent asphalt binder for 96 percent (4 percent air voids) design density at 75 gyrations with a Gmm of 2.521. The percent density of Gmm targets chosen in the test matrix represent densities that one may see if a pavement was under-compacted (88.5%) or compacted past the design potential (98.5%) which rarely ...
