Abstract:
Base course provides additional load distribution and
contributes to the sub-surface drainage. It may be composed of
crushed stone, crushed slag, and other untreated or stabilized
materials. Base course permeability plays an important role in
many pavement failures which are subjected to moisture-related
problems. Drainage capability, as indicated by permeability, is
also an important consideration when designing an unbound
granular base.
In this project we are trying to increase the permeability of
base course by changing percentage of medium size particle
keeping the strength within required limits. This is achieved by
preparing different samples of base course material with varying
percentage of medium size particles (passing through #4 sieves
and retained on #10). Test for permeability and strength will be
conducted to check the result
