Experimental Investigations of Effect of Sulphur on Beach Sand–Fly Ash–Asphalt (S-F-A) Paving Mixes
Abstract: The main components
of the flexible pavements are asphalt and aggregates. But in most of the places
in India there is shortage of the good quality aggregates (especially coarse
aggregates), at the same time beach sand is available in plenty in many
regions. Due to relative abundance of beach sand, the studies on the utilities
of the beach sand in paving mixes are worth taking up. But beach Sand-Asphalt
mix alone is not suitable for pavement construction, because of its low
stability and high air voids. In the present study, Sand-Fly
ash-Asphalt-Sulphur (S-F-A-S) mixes are being made in different proportions and
tested for their properties. Fatigue strength, stability, water sensitivity,
stiffness modulus and dynamic modulus tests are carried out at standard test
conditions and the results are analyzed for drawing conclusions. This study
investigates the potential use of abundant ingredients, which may replace the
ones which are scarce in nature.
