Solution
The correct option is B P−2;Q−1;R−4;S−3
* Soundness test is done to evaluate resistance against weathering of aggregate.
* Crushing test is done to evaluate strength of aggregate.
* Los angles abrasion test is to evaluate hardness of aggregate.
* Stripping value test is to evaluate ratio of uncovered area observed to the total area of aggregate. The test is conducted to determine the effects of moisture upon the adhesion of binding material.
