The correct statements regarding pavement material characterization are:
-
"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 (Vᵦ)."
Correct - VMA represents the total void space within the aggregate structure, including both air voids and bitumen. -
"The toughness and hardness of road aggregates are determined by Los Angeles abrasion test and aggregate impact test, respectively."
Incorrect -- The Los Angeles Abrasion Test measures the abrasion resistance (not toughness).
- The Aggregate Impact Test measures toughness (resistance to sudden impact), whereas hardness is generally evaluated using crushing strength tests.
-
"The load penetration curve of the CBR test may need origin correction due to the non-vertical penetrating plunger of the loading machine."
Correct - A non-vertical plunger can cause errors in the initial part of the CBR curve, requiring origin correction. -
"Grading of normal (unmodified) bitumen binders is done based on viscosity test results."
Correct - Bitumen binders are graded based on viscosity tests, which determine their performance in different temperature conditions.
