Description
Technical field
The invention belongs to pavement material technical field, be specifically related to a kind of inorganic modified Colophonium and preparation method thereof.
Background technology
Rut is the important disease that bituminous paving exists, and studies have found that, high temperature is the most direct inducement that rut produces,
High temperature makes the rheological property of Colophonium convert to plasticity from viscoelasticity, and stiffness modulus declines to a great extent, and its non-deformability drastically reduces,
Serious rut just occurs under the effect of vehicular load.At present, when solving the rut problem of bituminous paving, mainly take
Improving the technical measures of stability at high temperature of asphalt mixture, i.e. by asphalt modification being improved the high-temperature behavior of Colophonium, or using
Extruded aggregate aggregate grading etc. improves the rutting resistance of asphalt.Engineering practice proves the application of these technology also
Can not fundamentally solve rut problem.
Summary of the invention
The technical problem to be solved is for above-mentioned the deficiencies in the prior art, it is provided that a kind of inorganic modified Colophonium and
Its preparation method.This inorganic modified Colophonium with boracite and albite as primary raw material, make use of albite carrier function and
The hot-cast socket of boracite and thermal balance effect, under the carrier function of albite, the road surface Nei Ji that the factors such as solar radiation are caused
Heat build-up amount is diffused, and boracite utilizes bigger specific surface area and the heat comprehensive engagement of self, is absorbing Colophonium coagulation
Under conditions of soil heat, by the hot-cast socket performance of self, it is achieved the output of heat, thus reduce the internal total amount of heat of Colophonium,
Realize the cooling effect to bituminous paving, the notable high temperature rut disease alleviating bituminous paving；Meanwhile, in the winter time under low temperature condition,
Albite by the concave/convex-shaped structure of self, can change the specific heat capacity of asphalt material, hinders heat to scatter and disappear, meanwhile, and boracite
Then utilize the thermal balance of self, it is achieved the equivalent of heat is kept, thus reaches comprehensive heat accumulation purpose；Silica white can change
The high-temperature behavior of kind Colophonium；Microcrystalline Cellulose can improve the cryogenic property of Colophonium；Triethanolamine and auxiliary agent can the side's of enhancing boron
The compatibility between stone and albite and Colophonium.Temperature control effect of the present invention is notable, and can improve the pavement performance of Colophonium, with
Shi Chengben is relatively low, technique is simple, easy construction.
The technical solution used in the present invention is:
A kind of inorganic modified Colophonium, this inorganic modified Colophonium is become by the mixed raw material of following weight portion: basic asphalt 100 parts,
Boracite 5.5～15.5 parts, albite 3.5～10.5 parts, silica white 4～8 parts, microcrystalline Cellulose 1～2 parts, three second
Hydramine 0.5～1 part, auxiliary agent 2～4 parts；Described auxiliary agent is Iran's rubber oil tapped oil or furfural extract oil.
Preferably, the parts by weight of described raw material are: basic asphalt 100 parts, boracite 9.5～13.5 parts, albite
5.5～10.5 parts, silica white 6～8 parts, microcrystalline Cellulose 1.5～2 parts, triethanolamine 0.5～1 part, auxiliary agent 3～4 parts.
It is highly preferred that the parts by weight of described raw material are: basic asphalt 100 parts, boracite 10 parts, albite 8 parts,
Silica white 6 parts, microcrystalline Cellulose 1.5 parts, triethanolamine 1 part, auxiliary agent 3 parts.
Described basic asphalt is matrix pitch, SBS modified pitch, SBR modified pitch, rubber modified asphalt one therein.
