Abstract
The invention relates to a composition for the modification of asphalt, belonging to the technical field of asphalt material processing. The technical scheme is as follows: the composition for the modification of asphalt is composed of the following components in percentage by weight: 10-20% of CeO2 powder, 10-20% of MgO powder, 40-60% of kieselguhr and 20-30% of methyl silicone oil. The used CeO2 powder can increase the ageing resistance of the asphalt; the used MgO can increase the high-temperature resistance of the asphalt; and the used methyl silicone oil can reinforce the action of the CeO2 powder, the MgO powder, the kieselguhr and the asphalt and overcome the asphalt cracking problem.
Description
Technical field
The present invention relates to a kind of compsn that is used for asphalt modification, belong to the bituminous material processing technique field.
Background technology
Pitch is a kind of thermoplastic material, and bituminous pavement is aging in order to solve, the rimose problem, need carry out modification to pitch.At present mainly be to make through the mode modification that in pitch, adds polymkeric substance; Material commonly used mainly comprises butadiene-styrene thermoplastic elastomer, styrene-butadiene rubber(SBR), ethylene-vinyl acetate copolymer and Vilaterm etc., and the adding of these polymkeric substance can improve the bituminous temperature sensibility greatly.Through adding inorganic modified dose; Also can obviously improve the bituminous high and low temperature resistance; Patent ZL200610167622.9 discloses a kind of method of improving performance of diatomite modified asphalt material; It mainly is through utilizing surface-modifying agent that zeyssatite is carried out surface-treated, improve diatomite particle and bituminous consistency, and then significantly improves the performance such as high-low temperature resistant, intensity, toughness of diatomite modified asphalt ground surface material.
Summary of the invention
The objective of the invention is to have aging, rimose problem and a kind of asphalt modification compsn that is used for is provided to bituminous pavement.
The technical scheme that realizes the object of the invention is: a kind of compsn that is used for asphalt modification, and by CeO
2Powder, MgO powder, zeyssatite and methyl-silicone oil are formed, said CeO

CeO of the present invention
2Powder, MgO powder, zeyssatite and methyl-silicone oil are the commercially available prod, and wherein the viscosity of methyl-silicone oil is 10000～30000 mm
2/ S.
The working method of asphalt modification compsn of the present invention is: with above-mentioned materials of weight proportions, under 60～80 ℃ of conditions, stir even mixing, naturally cooling promptly gets the compsn of asphalt modification of the present invention.
Obvious advantage and effect that the present invention has:
1. the CeO that selects for use of the present invention
2Powder has ultraviolet and the anti-aging effect isolated, and improves the bituminous ageing resistance, and the MgO powder of selecting for use has high temperature resistance, characteristics that skeleton property is strong, improves the bituminous resistance to elevated temperatures.
2. the zeyssatite selected for use of the present invention promotes CeO as inorganic regulator
2Powder and MgO powder and bituminous effect improve CeO
2Powder and the dispersion stabilization of MgO powder in pitch.
3. the methyl-silicone oil selected for use of the present invention can be strengthened CeO
2Powder, MgO powder and zeyssatite and bituminous effect improve bituminous toughness, improve bituminous cracking problem.
4. this technology is simple, helps suitability for industrialized production.
