TAGISH’S ROLE. Prime Consultant
Upgrade and construct 6.3km of gravel road with a 9m asphalt finished surface c/w full depth waste excavation of subsoils and replacing with a granular structure consisting of 375mm depth of Designation 6 Class 125 granular sub-base, TriAx TX5 Geogrid, 150mm depth of Designation 2 Class 20 Granular base course and 125mm compacted depth of Asphaltic Concrete Pavement.
The addition of the TriAx TX5 Geogrid installed between the 6-125 sub-base and the150mm base course to provide the road with an even load displacement and solidarity, which will help to prevent pumping/heaving of the road structure caused by the freeze thaw cycle.
