Crushed sand for road construction with grain size up to 4 mm, obtained from rock crushing sift.

Purpose: for construction, repair, maintenance and reconstruction of public roads.
public roads.
Design features:
- Granulometric composition;
- Coarseness modulus, class
- Moisture
- Content of clay particles determined by swelling method
- Dusty and clay content;
- Sand grade by strength (crushability);
- Voidability
- True density
- Presence of organic impurities
- Bulk density;
- Specific efficiency of natural radionuclides activity;
- Content of harmful components and impurities
Advantages:
1. Wide range of products;
2. Bulk density coefficient of dolomite crushed stone is lower than that of granite crushed stone, therefore, at comparable strength and other characteristics the consumption of dolomite crushed stone will be less than that of granite crushed stone;
3. High level of sand grade in terms of strength;
4. High true density.
