7 LAB TESTS ON AGGREGATE TO CHECK QUALITY FOR USE IN

Sep 12 2015 · Several laboratory tests are conducted to arbitrarily determine the adhesion of bitumen binder to an aggregate in the presence of water. Static immersion test is one specified by IRC and is quite simple. The principle of the test is by immersing aggregate fully coated with binder in water maintained at 40 0 C temperature for 24 hours.
