  • Compressive Strength of Road PavementCivilWeb

    The compressive strength of road pavements is commonly specified in concrete road and pavement specifications. This however is slightly odd in that the compressive strength is not a critical parameter for pavement performance the flexural strength is much more important from a structural point of view.

     · The aggregates crushing value test should be performed as per IS code 2386 Part IV. First fill the sample aggregate with one-third of the cylindrical measure in three layers. Each layer should be tamped 25times freely. After filling the sample aggregate weigh and record it as W1. Now fill the aggregate in the mould along with the plunger on top.
