Description
Technical field
The present invention relates to a kind of high-modulus agent, and in particular to a kind of high-modulus agent for asphalt.
Background technique
High-modulus agent is a kind of additive that can significantly improve asphalt stiffness modulus and anti-fatigue performance.Addition
The bituminous concrete of high-modulus agent is known as high-modulus asphalt concrete, and high-modulus asphalt concrete passes through ebonite ramming material, high glue
The features such as ramming material dosage, low porosity, realizes the purpose for improving stiffness modulus and anti-fatigue performance.
The system that high-modulus agent in the prior art mainly depends on traditional high-modulus agent is developed and is improved, but due to
The development of these high-modulus agent systems has tended to be mature, has tended towards stability in terms of the modification amplitude to pitch, therefore, how to have improved
The performance indicators such as the anti-fatigue performance of asphalt, the stability of high/low temperature, anti-rut behavior become the following high-modulus agent
Need improved direction.
Summary of the invention
In view of the deficiencies of the prior art, the purpose of the present invention is to provide a kind of high-modulus for asphalt
Agent.
Technical solution of the present invention is summarized as follows:
A kind of high-modulus agent for asphalt, by parts by weight in terms of, including following components:
Preferably, the high-modulus agent for asphalt, wherein further include having 0.2-0.3 parts by weight
α-naphthylacetic acid.
Preferably, the high-modulus agent for asphalt, wherein further include having 0.2-0.3 parts by weight
Indole-3-acetic acid.
Preferably, the high-modulus agent for asphalt, wherein further include having 0.2-0.3 parts by weight
Furfural acetone resin.
Preferably, the high-modulus agent for asphalt, wherein the number-average molecular weight of the furfural acetone resin
For 7000-8000g/mol.
Preferably, the high-modulus agent for asphalt, wherein the number-average molecular weight of the epoxy resin
For 3000-5000g/mol.
The beneficial effects of the present invention are: this case is by improving the formula of existing high-modulus agent, by multiple components into
Row organic combination improves the main performance index such as the fatigue resistance of asphalt, the stability of high/low temperature and Rut resistance,
There is significant help to the track disease for mitigating bituminous pavement.
Specific embodiment
The present invention will be further described in detail below with reference to the embodiments, to enable those skilled in the art referring to specification
Text can be implemented accordingly.
This case provides the high-modulus agent for asphalt of an embodiment, by parts by weight in terms of, including with the following group
Point:
It wherein, further preferably include the α-naphthylacetic acid of 0.2-0.3 parts by weight.
It wherein, further preferably include the indole-3-acetic acid of 0.2-0.3 parts by weight.
It wherein, further preferably include the furfural acetone resin of 0.2-0.3 parts by weight.
Wherein, the number-average molecular weight of furfural acetone resin is preferably 7000-8000g/mol.
Wherein, the number-average molecular weight of epoxy resin is preferably 3000-5000g/mol.
High-modulus agent the preparation method comprises the following steps: by the stirring and dissolving in organic solvent of each component in formula, and mix well,
Then solvent is drained to get high-modulus agent.
The additive amount of high-modulus agent is the 0.2-1wt% of asphalt.
Table 1 list different embodiment 1-8 high-modulus agent and gained modified asphalt mixture (90# asphalt+
The agent of 0.2wt% high-modulus) performance indicator:
Table 1
Although the embodiments of the present invention have been disclosed as above, but its is not only in the description and the implementation listed
With it can be fully applied to various fields suitable for the present invention, for those skilled in the art, can be easily
Realize other modification, therefore without departing from the general concept defined in the claims and the equivalent scope, the present invention is simultaneously unlimited
In specific details.
