Question

Group-I gives a list of test methods for evaluating properties of aggregates. Group-II gives the list of properties to be evaluated. Group-I: Test methods Group-II: Properties P. Soundness test 1. Strength Q. Crushing test 2. Resistance to weathering R. Los Angeles abrasion test 3. Adhesion S. Stripping value test 4. Hardness The correct match of test methods under Group-I to properties under Group-II, is

Correct answer (B) P-2; Q-1; R-4; S-3 Solution The matching of aggregate tests to the properties they evaluate is as follows: Soundness test (P) : Evaluates the resistance of aggregates to weathering action (durability) due to cycles of wetting/drying or freezing/thawing. (Matches 2) Crushing test (Q) : Evaluates the compressive strength of aggregates under a gradually applied load. (Matches 1) Los Angeles abrasion test (R) : Evaluates the hardness or resistance of aggregates to surface wear and attrition. (Matches 4) Stripping value test (S) : Evaluates the adhesion of bituminous binder to the aggregate surface in the presence of water. (Matches 3) Therefore, the correct match is P-2, Q-1, R-4, S-3, which corresponds to option B. Turn this into a strength. Explore AI-powered practice and doubt support with Success Tracker.
