Bitumen 90,Asphalt,Asphaltic 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
deasphalting process, also can use different penetration and
ductility level made by asphalt 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 asphalt (add rubber said rubber asphalt, 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 deasphalting process and made by blending method. Also can
be used as emulsifying asphalt and diluted asphalt materials.
the main use Suitable for paving, light traffic road asphalt
