Proctor and CBR for Soil & GSB
Proctor and California Bearing Ratio (CBR) Testing are essential laboratory tests used to evaluate the compaction characteristics and load-bearing capacity of Soil and Granular Sub-Base (GSB) materials used in road, pavement, and infrastructure projects. These tests help determine the optimum moisture content, maximum dry density, and strength characteristics required for the design and construction of durable pavement structures.
The Proctor Test establishes the relationship between moisture content and dry density, while the CBR Test assesses the resistance of soil and GSB materials to penetration under controlled conditions. Together, these tests provide critical data for pavement design, quality control, and construction planning.
Key Applications:
Road and Highway Construction
Flexible and Rigid Pavements
Airport Runways
Embankment and Earthwork Projects
Industrial Yards and Parking Areas
Infrastructure Development Projects
