Description
Technical field
The invention belongs to Expressway Pavement Material technical fields, and in particular to a kind of water-permeable colored pitch and its production technology.
Background technique
With the development of economy with the continuous improvement of scientific and technological level, people have the coordination performance of road and environment
Understanding more profound also has higher requirement the comfort and functionality of road.Colorful Asphalt Pavement is as a kind of novel
Paving technology, exactly meet these requirements, cause the extensive concern of people.Color asphalt concrete is used in the road
It is laid with road surface, mainly there are two big functions: 1. beautifying city, road improvement environment, Urban style effect is shown, is applied particularly to
Avenue, square, scenic spot, park and tourist sight road etc.；2. inducing wagon flow, change traffic administration intuitively, specifically answers
Increase the traffic capacity and traffic peace of road with the section and lane for distinguishing different function to improve the recognition effect of driver
Entirely.
Currently, Colorful Asphalt Pavement making is mainly divided to two classes: the first kind is spray coating method, and the method is convenient for construction, low cost
It is honest and clean but not durable；Another kind of to mix chromatic bitumen mixture spreading method for heat, the color persistence of the method is longer.Heat mixes colored drip
Blueness is by early stage asphalt decoloration preparation till now using main materials systems such as resinous material, base oil, high molecular polymers
It is standby.Production cost and technology difficulty all reduce very much, and technology is more mature, and present heat mixes the ductility of color asphalt, high temperature
Stability, low-temperature cracking-resistance and durability are more preferable.
China sponge city pilot is carried out in succession, and color asphalt drainage pavement is also more and more prominent in sponge urban construction
Out, however, this is also to the cementitious matter of color asphalt drainage pavement, more stringent requirements are proposed: the 1. viscosity and softening of color asphalt
Point is very high, to meet the structural strength of macroporosity drainage pavement, to resist traffic load and external environment active force；②
Cementitious matter will also have enough anti-aging and anti-water damage property.
In the prior art, usually addition SBS modifier improves the performance of color asphalt into color asphalt, but
When preparing color asphalt, addition SBS modifier usually requires high speed shear, not only increases preparation section in this way, it is also necessary to
It increases manufacturing facilities more.
Summary of the invention
Technical problem to be solved by the invention is to provide a kind of water-permeable colored pitches, needed for production compared with the prior art
Temperature is low, energy saving, and does not need high speed shear during the preparation process, without additional addition equipment, reduce production cost and
Process, and obtained water-permeable colored pitch excellent combination property meet " urban road colour asphalt pavement technology rule
Journey " extraordinary color asphalt technical requirements in CJJ/T218-2014.
To achieve the above object, the present invention adopts the following technical scheme:
A kind of water-permeable colored pitch, is made of raw material from the following weight: 40-55 parts of Petropols, furfural extract oil 30-
