Engineering characteristics of crushed stone and coal ash

2012-4-29  Crushed stone compaction piles are widely used for soft ground improvement because the installed piles improve both overall composite capacity and discharge capacity. However, discharge capacity declines when clogging occurs due to clay penetrating into the voids of crushed stone compaction piles over time.

Some properties of crushed stone for road surfaces

On wet roads a sufficiently rough surface texture on the macroscale is necessary to ensure rapid removal of water from the contact zone between the tire and road surface, especially at high speeds.For this surface texture on the macroscale, beside the particle size of the aggregate also the resistance to crushing and abrasion is rather important.The macroroughness is likely to decrease rapidly
