The way in which the test was done, was to crush 9.5 mm aggregate in a steel cylinder (in the compression testing machine) to yield a percentage fines between 7.5% and 12.5% and record the force required to produce this percentage (Figure 4). The force obtained for wet and dry conditions was then expressed as a percentage (wet-to-dry ratio).

Dec 24,  · AbstractBitumen holds the aggregate in hot mix asphalt (HMA). Without asphalt binder, HMA would simply be crushed stone or gravel. A bitumen batching system (BBS) is comprised of bitumen storage, transportation, weighing and discharge equipment in an asphalt mixing plant (AMP). The function of the equipment is to batch the binder heated up to working temperature and to discharge it into a
