Geotechnical Engineering Question on Deep foundations
In the context of pavement material characterization, the CORRECT statement(s) is/are
The load penetration curve of CBR test may need origin correction due to the non-vertical penetrating plunger of the loading machine.
The toughness and hardness of road aggregates are determined by Los Angeles abrasion test and aggregate impact test, respectively.
Grading of normal (unmodified) bitumen binders is done based on viscosity test results.
In compacted bituminous mix, Voids in the Mineral Aggregate (VMA) is equal to the sum of total volume of air voids (Vv) and total volume of bitumen (Vb).
The load penetration curve of CBR test may need origin correction due to the non-vertical penetrating plunger of the loading machine.
Solution
The correct option is (A) : The load penetration curve of CBR test may need origin correction due to the non-vertical penetrating plunger of the loading machine, (C) : Grading of normal (unmodified) bitumen binders is done based on viscosity test results and (D) : In compacted bituminous mix, Voids in the Mineral Aggregate (VMA) is equal to the sum of total volume of air voids (Vv) and total volume of bitumen (Vb).
