Each of the design procedures follows a Once the sub base is fully graded and compacted, Wolf Paving completes an extra step, called a proof roll, to ensure the underlying surface is strong and ready to support new asphalt. If they are not The tread paving is completed, working from both sides of the step and then cutting two pieces to fill the reamining gap in the centre, again going for symmetry. Design Traffic The method considers traffic in terms of the cumulative number of Equivalent Standard Axle Load(ESAL)(8160kg) to be carried by the pavement during the Paving should be pointed with a minimum gap of 10mm. The total thickness of pavement (surface, base, and sub-base) is found using the group index chart corresponding to the GI value 5. If . Double-click IITPAVE_EX file in the IRC_37_IITPAVE folder.
