density of asphalt binder

Standard asphalt density is 145lbs/ft3 or 2322kg/m3. The asphalt unit weight is 2243 per cubic meter. Therefore 2.4 ton of asphalt = 1 cubic meter. 1 cubic yard of hot asphalt mix weighs 2.025 tons or 4050 lbs. These measurements are an approximation and therefore when you are ordering the quantity ensure that you add more asphalt …

An asphalt mixture contains 115.7 g of binder and 2573.5 g of aggregate. Determine the % binder and % stone of the mixture to the nearest 0.1 %. 2. The binder content for several asphalt samples are shown below. Determine the % stone in each of the mixtures. Pb

Asphalt concrete (commonly called asphalt, blacktop, or pavement in North America, and tarmac, bitumen macadam, or rolled asphalt in the United Kingdom and the Republic of Ireland) is a composite material commonly used to surface roads, parking lots, airports, and the core of embankment dams. Asphalt mixtures have been used in pavement construction since the beginning of the twentieth century.

This test method covers the determination of fracture energy density of asphalt binder by means of a direct tension test. For evaluation of relative cracking performance, it is recommended that this test procedure be used with asphalt binder aged using T 240 (RTFO) plus R 28 (PAV).

It consists of asphalt and continues graded aggregate mixed, casted and compacted in hot mixture at certain temperature. Mechanical strength of the mixture is obtained from the friction between the grains of aggregate and the quality of asphalt as a binder. * Corresponding author.

Several trial blends of aggregate and asphalt binder are prepared in laboratory-scale mixers with binder contents at, above, and below the estimated optimum in increments of 0.5%. Each trial mix must contain enough material to compact three specimens for stability and flow measurements, usually about 2.6lb (1.2kg) for each specimen.

Particle Absorption takes place at high temperature and usually reaches a maximum in 1 - 6 hours, depending on the absorptiveness of the aggregate (Most aggregates

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.

Typical values for bulk specific gravity range from 2.200 to 2.500 depending upon the bulk specific gravity of the aggregate, the asphalt binder content, and the amount of compaction. Absorption should typically be below 2 percent. If more than 2 percent water by volume is absorbed by the sample then this method is not appropriate.

1 Figure 2b shows that the density of the WPRMA decreases, then increases sharply, then decreases slightly, and finally trends to a constant (1.02 g/cm 3). Moreover, the constant density values are equal to the real density values of asphalt, which suggests that the molecular models can be used to simulate the properties of WPRMA.
