Testing of materials and structures for road construction and engineering infrastructure

We offer a wide range of physical and mechanical tests for the following objects:

Soils
Soil classification, determination of optimal moisture content and maximum density, assessment of soil compaction quality, filtration, etc.
Fine (sand) and coarse (crushed stone and gravel) natural fillers, crushed stone-sand, gravel, gravel-sand mixtures
Determination of grain composition, content of dust and clay particles, clay in lumps, content of plastic and needle-shaped grains, determination of grade by strength, abrasion, resistance to crushing, etc
Concrete, cement, concrete and reinforced concrete products
Determination of cement quality, selection of concrete composition, determination of quality indicators of concrete mixtures and concrete (mobility, stiffness, air content, strength, frost resistance, water permeability, etc.
Petroleum bitumen, bitumen emulsions
Determination of viscosity, softening point, brittleness temperature, tensile strength, adhesion to glass and mineral materials, flash point, change in indicators after ageing using various methods, selection of emulsion composition, determination of emulsion homogeneity, residual binder content, storage stability
Asphalt concrete, bituminous mineral mixtures for roads
Selection of the composition of asphalt concrete and bituminous mineral mixtures, sampling from existing layers of asphalt concrete, determination of the compliance of asphalt concrete and asphalt concrete mixtures with the requirements of regulatory documents
Bricks and ceramic blocks, facing bricks, silicate bricks
Determination of physical and mechanical properties of bricks and ceramic blocks
Ceramic tiles
Geometric dimensions, water absorption, destructive load, flexural strength, etc.
Roofing and waterproofing materials
