3. Polymer Modified Bitumen
Process Description
Bitumen Emulsion
Process Description
A bitumen emulsion is bitumen, which has been converted to a fine suspension of bitumen droplets in water, usually by
means of a high energy shearing device called a "colloid mill". These droplets are prevented from agglomerating by the
action of chemical emulsifiers which cause the surface of the droplets to become charged and hence repel each other.
In emulsified form bitumen can be handled at ordinary
temperatures and this eliminates the need of
expensive solvents as diluents.
In the first stage, the hot bitumen is pumped at the required temperature (usually
around 185ºC) into agitated tank. The thermo-plastic rubber is added and stirred
for equal distribution. Following the mix flows to the mill by gravity.
The mix is passed through the mill to physically reduce the thermo-plastic rubber
particles in size by mechanical shear, accompanied by a significant input of heat
energy. This provides rapid and efficient disintegration of the thermo-plastic
rubber particles in the bitumen.
The most common production configuration is the batch production where all
chemical products converge into a reactor followed by recirculation through a
high shear mill, to achieve homogeneity and final properties.
Lower Thermal susceptibility
Higher cohesion
Higher elastic response
Higher water resistance
Higher resistance to aging
The modification process improves
the final characteristics such as:
