To investigate sub-soil condition, collect disturbed /undisturbed soil/rock samples, conduct various tests to determine and classify soil/rock strata, ascertain safe bearing capacity.
Borrow Area- Soil, Existing Pavement Crust Materials, In-situ tests (CBR, Compaction), Quarries/Mines (Fine Aggregate, Coarse Aggregate) Core Cutting.
Plate Load Test, SPT, Traffic Survey.
Rebound Hammer Test, UPV Test, Half Cell Potentiometer Test, Carbonation Test, Cover Meter, Span Load Test, Pile Load Test, Pile Integrity Test, BBD, FWD, NSV, Axle Load, Road Roughness.
Using characteristic deflection and remaining life of pavement through non-destructive/ destructive techniques.
Visual Inspection and assessment of the condition of the pavement surface, Functional condition of pavement with the help of roughness, rutting and skid resistance.
By using NDTs like UPV, Rebound Hammer, Half Cell Potentiometer etc. or by using destructive tests like Core cutting and testing.
Visual Inspection and assessment of the condition of the structures such as Buildings, Bridges, Flyovers, Robs, Underpasses, Functional condition of structures by conducting Span Load test.
