Normal practice is to heat bitumen to reduce its viscosity. In some situations, preference is given to use liquid binders such as cutback bitumen. In cutback bitumen suitable solvent is used to lower the viscosity of the bitumen. From the environmental point of view also cutback bitumen is preferred. The solvent from the bituminous material will evaporate and the bitumen will bind the aggregate. Cutback bitumen is used for cold weather bituminous road construction and maintenance. The distillates used for the preparation of cutback bitumen are naphtha, kerosene, diesel oil, and furnace oil. There are different types of cutback bitumen like rapid curing (RC) , medium curing (MC) , and slow curing (SC). RC is recommended for surface dressing and patchwork. MC is recommended for premix with less quantity of fine aggregates. SC is used for premix with the appreciable quantity of fine aggregates.

Epoxy resins are used in the manufacture of adhesives, plastics, paints, coatings, primers and sealers, flooring and other products and materials that are used in building and construction applications. Epoxies are thermoset plastics made by the reaction of two or more industrial chemical compounds.

Cutback bitumen is used for cold weather bituminous road construction and maintenance.

In filling the road patches cutback bitumen used. For cracks in building plastic bitumen used.

For roads maintenance cut back bitumen and for building maintenance plastic bitumen is used.

Plastic bitumin is applied on walls where as cut back bitumin is used for road works.

Plastic bitumen is easy to apply, its actually a mixture of cement and bitumen.

Plastic bitumen provide smooth coating and easy to apply over masonary wall.

Why using the plastic bitumen?

Please explain the reason.

Plastic bitumen is the mixture of bitumen and cement.
