Description
Technical field
The invention belongs to pavement material technical field, and in particular to a kind of chromatic bituminous cement and its preparation technology.
Background technology
Bituminous paving has enough intensity, higher damping and tire adhesion force is good, easy to clean good with maintenance etc.
Performance, is widely used in high-grade highway at home and abroad.But for a long time, bituminous paving generally only has a kind of this face of black
Color, this is in rapid economic development, today that living environment color appears, vert space is increasingly focused on, the asphalt road of black
Face will seem dull and dull.And the bituminous paving of black and road surrounding environment inaccurate coordination, road landscape is influenceed,
And the heat absorption of bituminous paving exacerbates " heat island " effect in city, directly influences daily routines and the living standard of people.
With the development of the social economy, the progress of science and technology, Colorful Asphalt Pavement causes more and more multinational in the world
The concern of family.Chromatic bituminous cement is, by light-colored resin, high one's share of expenses for a joint undertaking polymer and filling oil, some outer-penetrating agents to be added, in height
Utilized under the conditions of temperature after high speed shear instrument shear agitation, then add pigment academic title.Chromatic bituminous cement has good extension
Property, color is more stable, not fugitive color.
Colorful Asphalt Pavement has obvious advantage compared with plain asphalt road surface, but at present only in some large- and-medium size cities
It is applied, in small and medium-sized cities but using seldom, this cost for being mainly Colorful Asphalt Pavement constrains Colorful Asphalt Pavement
Popularization and application.The cost of plain asphalt is generally 5000 yuan/t, and the cost of color asphalt binder is about 1.5 ten thousand yuan/t~2
Ten thousand yuan/t, be 3~4 times of common petroleum pitch.While chromatic bituminous cement less stable, softening point is typically on 50 DEG C of left sides
The right side, causes the anti-aging intensity of color asphalt also poor.Accordingly, it is capable to the cost of no reduction Colorful Asphalt Pavement and to improve its stable
Property, it is directly connected to the popularization and application of Colorful Asphalt Pavement.
The content of the invention
The technical problem of solution：Present invention aim to address existing chromatic bituminous cement stability is poor, cost is high
Technical problem can not only improve the stabilization of chromatic bituminous cement there is provided a kind of chromatic bituminous cement and its preparation technology
