Bypass roads play a crucial role in
traffic management, especially during
construction.
Dust emission on temporary unpaved
bypass roads is a significant issue due
to minimal treatment.
The lack of continuous usage and
extended accessibility (sometimes
over six months) amplifies the dust
problem.
INTRODUCTION
Water spray application is a
common but temporary
solution with drawbacks like
short retention time and
potential road damage.
Extended water application
leads to land erosion,
increasing project costs.
CHALLENGES OF DUST CONTROL
ON UNPAVED BYPASS ROADS
EFFECTIVE SOLUTIONS
FOR DUST CONTROL
Include bitumen
emulsions, polymer soil
stabilizers,
lignosulfonates, and
surfactants.
Purpose: Bind soil
particles, preventing
dust emission and
enhancing road
strength.
Dust Control Binders
Composition: Tiny bitumen droplets
suspended in water using an
emulsifying agent.
Application: Applied through spray
trucks or equipment for even
distribution.
Effect: Penetrates and binds soil
particles, creating a stable mixture.
