What is the density of asphalt pavement?
Standard density for asphalt is 145 lb/ft3 (2322 kg/m3). Multiply the volume by the density (in the same units) to get the weight.
What is the density of asphalt binder?
1. The mixing temperature range is defined as the range of temperature where the unaged asphalt binder has a kinematic viscosity of 170 + 20 mm2/s (approximately 0.17 + 0.02 Pa-s for an asphalt binder density of 1.00 g/cm3) measured in accordance with ASTM D 4402.
What is the unit weight of asphalt concrete?
Asphalt Mixture typically weighs from 142 to 148 pounds per cubic foot (PCF) in-place. Use 148 PCF. Calculate the tonnage needed. (remember to convert from pounds to tons; 2000 pounds per ton).
What is the density of gravel?
The bulk density of gravel varies from 1,460 to 1,920 kg/m3 (2,460 to 3,240 lb/cu yd). Natural gravel has a high hydraulic conductivity, sometimes reaching above 1 cm/s.
What is the density of aggregate base?
Most aggregates have a relative density between 2.4-2.9 with a corresponding particle (mass) density of 2400-2900 kg/m3 (150-181 lb/ft3).
What is base coarse gravel?
ABCM Aggregate Base Coarse is a hard pack sub-base compaction material. Contains a mix of crushed stone, topsoil and dust. Cross-Section layers that make up a mortar-less or “dry-laid” pavement.
How do you find the density of asphalt?
The test method used to determine the density of in- place hot mix asphalt pavements is the backscatter method, whereby the source is lowered into near contact with the compacted roadway surface. The direct transmission and air gap methods are not used to test the in-place density of bituminous pavements..
What is density of coarse aggregate?
The coarse aggregate density used for construction is generally between 1450 – 2082 kg/m3 The density of coarse aggregate varies depending on the source, nature, and condition like wet or dry.
What is the aggregate type for base course?
Aggregates: Aggregates for bases shall be crushed stone, crushed slag, crushed gravel or natural gravel that conforms to the quality requirements of AASHTO M147, except that the requirements for the ratio for the minus No.
What is the density of aggregate?
What is the unit weight of coarse aggregate?
For example, the specific gravity of a dry coarse aggregate (Gs) is 2.65. The unit weight of water is 62.4-lb/cu ft.
