Description
Technical field
The present invention relates to a kind of asphalt more particularly to a kind of warm mix waste rubber powder modified asphalt mixture and its preparations
Method belongs to modified asphalt material technical field.
Background technique
Waste old is the internationally recognized solid waste that influences environment and must handle.Automobile tire is generally using
It is scrapped in 2-3 afterwards, therefore, wants the waste rubber tire that production quantity is surprising every year in the world.Rubber for tire through over cure at
Reason, has special cross-linked structure, and recycling and reusing is more difficult.Damaged tire is different from the waste and rubbish of other types
Rubbish cannot be handled with landfill method, still, long-term to stack if cannot handle in time, by the health to natural environment and the mankind
It causes to seriously affect.Therefore, the discarded of rubber tyre has become a kind of public hazards.In order to protect environment and turn waste into wealth, rubber is discarded
The utilization of rubber tire tire is put on agenda by each Main Developed Countries in the world already.In addition to retread, reclaimed rubber and Re Li
With can handle outside a part of waste and used rubber tyre, among the construction of asphalt roads, be big batch processing waste old compared with
Good selection.
Rubber modified mixes have decrease of noise functions, and can improve cryogenic property, at present the paving of rubber asphalt
If most of still use high temperature mix, temperature is more than 180 DEG C, and higher than the temperature of mixing and stirring of plain asphalt, high temperature process is not only needed
The a large amount of energy is consumed, and in the construction process, many flue dust and exhaust gas can be generated, the body for endangering construction personnel is strong
Health, the carbon dioxide given off can generate greenhouse effects again, and environmental pollution is serious, thus rubber modified mixes production is only
It is limited to daily 1000t.The use of warm mix technology will be helpful to the large scale application of modified asphalt mixture.It simultaneously again can be with
Push the exploitation of warm-mixed asphalt concrete road surface decrease of noise functions.
Although having the example that warm mix technology is applied to waste rubber powder modified asphalt in the prior art, for example, application No. isCN201110262504.7Patent, and application No. isCN201310736778.4Patent, still, the application and the prior art
No matter raw material selection or in terms of all there is relatively big differences.
Summary of the invention
The present invention provides a kind of warm mix waste rubber powder modified asphalt mixture and preparation method thereof, by by warm-mixing agent and each group
