Stripping Value Test on Aggregates Objectives, Lab Procedure

The procedure of Stripping Value Test on Aggregates The procedure of the stripping value test involves the following series of steps: 1. A well-cleaned aggregate sample passing through a 20mm IS sieve and retained on a 12.5mm sieve is taken. 2. About 200gm of the sample is heated in the oven at a temperature of about 150 degree Celsius. 3.
