Description
Technical field
The invention belongs to road engineering uses field of material technology, and in particular to a kind of energy saving and environment friendly pitch and its preparation
Technique.
Background technology
It is one long-term strategic task of China to build a resource-conserving and environment-friendly society, in road project
In, China《Communications and transportation " 12 " development plan》Warm-mixed asphalt is paved the way technology as highway construction energy-saving and emission-reduction demonstration
Promote engineering.But at present both at home and abroad warm mix technology is while bituminous mixture construction temperature is reduced, also can necessarily journey
The part pavement performance of compound is damaged on degree, and warm-mixing agent price is generally expensive, while the production for needing addition special sets
It is standby, hinder its popularization and application.Simultaneously substantial amounts of CO is also discharged in construction in bituminous paving2、CO、SO2And NOxDeng gas and
Dust, and more multi-energy is consumed in bituminous mixture, thus exacerbates the destruction to environment and to can not be again
The consumption in production-goods source, along with serious waste of resources such as straw, animal wastes, white garbage cannot be recycled, these
The theory of sustainable development is not necessarily met.Additionally, urban road is typically all constructed at night, temperature is relatively low, cold district and
Highlands, also than relatively low, the construction temperature having high demands in low ambient temperature conditions must be paid more its environment temperature
Big cost.So, using a kind of energy saving and environment friendly pitch, waste resource is made full use of, asphalt pavement construction temperature is reduced, subtract
The discharge of of low pollution gas, energy saving and resource, so as to effectively alleviate deficiency above, while improving the road of asphalt
Use performance.
The content of the invention
For the deficiencies in the prior art, it is an object of the present invention to provide a kind of low energy-saving ring of construction temperature
Guarantor's type pitch and its preparation technology.
