Petroleum Aslt Specification:
Bitumen 60/70,Aslt,Asltic bitumen
1, black, good rheological property, persistent adhesion sex jostled, rutting resistance, resistance to deformation ability. With the appropriate properties of crude oil vacuum distillation, often also can vacuum residuum oxidized by shallow or propane deaslting process, also can use different penetration and ductility level made by aslt mixed preparation.
USES: mainly used for paved road and caking agent for roofing materials. With a rubber or other high molecular compound put sex of road aslt (add rubber said rubber aslt, its 3% ~ 10%) of the total amount for the rubber, can be used to construct high-level highway pavement, airport runway and important traffic crossing the road surface under high load.
2, product performance, Room temperature for glossy black semisolid, heating melting gradually, soluble in organic solvents. The product has good fluidity, thermal stability, lasting adhesion, elastic-plastic, electrical insulation and water resistance.
3, the production method Often by the crude oil vacuum distillation or residue by oxidation and made by blending, also can by the solvent deaslting process and made by blending method. Also can be used as emulsifying aslt and diluted aslt materials.
Application
the main use Suitable for paving, light traffic road aslt pavement.
