Purpose: used in construction, repair, overhaul, reconstruction and maintenance of public roads.
Design features:
- Granulometric composition, Mark;
- Content of grains of lamellar (flatter) and needle-shaped;
- Content of grains of weak rocks;
- Clay content in lumps;
- Dusty and clay content;
- Crushed stone grade by strength (crushability);
- Grade of crushed stone by frost resistance;
- Mark on resistance to crushing and wear;
- Structure stability against disintegration (loss of mass during disintegration);
- Bulk density;
- Specific efficiency of activity of natural radionuclides;
- Content of harmful components and impurities;
Advantages:
1. Wide range of products;
2. Mineral composition of dolomite crushed stone in contrast to crushed stone from acid granites provides better adhesion of crushed stone with bitumen, which reduces the consumption of binding materials;
3. The percentage of content of grains of lamellar and needle-shaped form does not exceed 13%, by.....
