Pavement materials: Bitumen

The specific gravity of bitumen varies from 0.97 to 1.02. Viscosity test Viscosity denotes the fluid property of bituminous material and it is a measure of resistance to flow. At the application temperature, this characteristic greatly influences the strength of resulting paving mixes.

5.0 BITUMINOUS LAYERS AND MIXES (Specification 3.4 to 3.12)

A bituminous prime coat is a thin layer of bitumen sprayed on to a prepared road base. Either MC 30 or MC 70 cut back bitumen should be used, which should be sprayed within the temperature range included in Table 5.1. The prime coat will normally be sprayed from a spray bar at the rear of a bitumen

Cutback Bitumen, Iran Cutback Bitumen, RC - MC - SC, 30, 70

Cutback bitumen is divided into three categories based on viscosity grade. Rapid-Curing – RC. RC cutback bitumen is manufactured by solving bitumen in gasoline, so evaporation occurs quickly and the bitumen is deposited. Medium-Curing – MC . MC cutback bitumen is manufactured by solving bitumen in kerosene, so evaporates more slowly than ...

BNA Cutback Grade Bitumen is normally used in spraying and in some mixing application. Cutback Bitumen is penetration grade bitumen blended with a solvent such as kerosene, white spirit, gasoline and naphtha controlling the curing time. Cutbacks are divided into 2 types, Rapid Curing (RC) and Medium Curing (MC) depending on the solve used.

DESCRIPTION MC 30™ is a blend of medium curing petroleum solvents and penetration grade bitumen. USES MC 30™ is used for priming newly constructed, crushed stone- or natural gravel base courses prior to surfacing.

Recyclers and soil stabilizers

The recyclers have a variable mixing chamber and microprocessor-controlled injection systems for the addition of bitumen emulsion, water and foamed bitumen. In the soil stabilization process, the all-wheel drive, all-terrain machines mix binding agents into existing soils, producing load-bearing soils with ideal properties for further roadworks.
