Max size of aggregate and Nominal size of aggregate

Maximum size. The smallest sieve through which 100 percent of the aggregate sample particles pass.  Superpave defines the maximum aggregate size as "one sieve larger than the nominal maximum size"

Nominal maximum size. The largest sieve that retains some of the aggregate particles but generally not more than 10 percent by weight.  Superpave defines nominal maximum aggregate size as "one sieve size larger than the first sieve to retain more than 10 percent of the material"

Softening point IS 1205 1978

Hot the bitumen in oven or on hot plate at 75oc – 110oc above softening point say at 90oc + softening point of bitumen and pour it in the rings Balls weights 3.5 gms and dia of Ball is 9.5 mm After 30 min in air place it in beaker 600 ml and keep it in apparatus the temp of Distilled water should be 0oc and heat it at the rate of 5oc /min place the thermometer and note down the temp when balls touched the lower plate. For CRMB 55 the Softening point is 55oc For CRMB 50 the softening point is 50oc And For CRMB 60 the Softening point is 60oc For Bitumen having the Softening point above 80oc use Glysrine in place of water and the starting temp should be 35oc In IS 1205 1978 the water bath is written to perfotm the test first keep the beaker with sample in water bath for 15 min at 5oc and then allow to rise the temp at 5oc per min.

Shear Strength of concrete

Concrete subjected to bending and and shear stress is accopanied by tensile and compressive stress. The shear failure are due to resulting diagonal tension. The shear strength is generally 12 to 13 percent of compressive strength.
