Abstract
The invention relates to a high-modulus agent for an asphalt mixture. The high-modulus agent comprises the following components in parts by weight: 100 parts of gypsum fiber, 12-14 parts of epoxy resin, 2-3 parts of sodium carboxymethyl cellulose, 4-5 parts of coker gas oil and 2-3 parts of calcium chloride. In the invention, by improving the formula of the existing high-modulus agent and organically integrating multiple components, main performance indexes of the asphalt mixture, such as fatigue resistance, high- and low-temperature stability and track resistance, are improved, and the reduction of track diseases of asphalt pavements is remarkably facilitated.
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 technology
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 referred to as high-modulus asphalt concrete, and high-modulus asphalt concrete passes through ebonite ramming material, glue high
The features such as ramming material consumption, low porosity, realizes improving the purpose of stiffness modulus and anti-fatigue performance.
The system that high-modulus agent of the prior art mainly depends on traditional high-modulus agent is developed and improved, but due to
The development of these high-modulus agent systems has tended to ripe, has been tended towards stability in terms of the modified amplitude to pitch, therefore, how to improve
The performance indications such as the anti-fatigue performance of asphalt, the stability of high/low temperature, anti-rut behavior, become following high-modulus agent
Need improved direction.
The content of the invention
In place of in view of the shortcomings of the prior art, it is an object of the invention to provide a kind of high-modulus for asphalt
Agent.
Technical scheme is summarized as follows：
A kind of high-modulus agent for asphalt, it is with weight portion to count, including following components：
Preferably, the described high-modulus agent for asphalt, wherein, also include 0.2-0.3 weight portions
NAA.
Preferably, the described high-modulus agent for asphalt, wherein, also include 0.2-0.3 weight portions
Indole-3-acetic acid.
Preferably, the described high-modulus agent for asphalt, wherein, also include 0.2-0.3 weight portions
Furfural acetone resin.
Preferably, the described high-modulus agent for asphalt, wherein, the number-average molecular weight of the furfural acetone resin
It is 7000-8000g/mol.
Preferably, the described high-modulus agent for asphalt, wherein, the number-average molecular weight of the epoxy resin
It is 3000-5000g/mol.
The beneficial effects of the invention are as follows：This case is improved by the formula to existing high-modulus agent, and multiple components are entered
Row organic combination, improves the main performance index such as the fatigue resistance of asphalt, the stability of high/low temperature and Rut resistance,
Rut disease to mitigating bituminous paving has significantly help.
Specific embodiment
With reference to embodiment, the present invention is described in further detail, to make those skilled in the art with reference to specification
Word can be implemented according to this.
This case provides the high-modulus agent for asphalt of an embodiment, its with weight portion to count, including with the following group
Point：
Wherein, the NAA of 0.2-0.3 weight portions is further preferably included.
Wherein, the indole-3-acetic acid of 0.2-0.3 weight portions is further preferably included.
Wherein, the furfural acetone resin of 0.2-0.3 weight portions is further preferably included.
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.
The preparation method of high-modulus agent is：By the stirring and dissolving in organic solvent of each component in formula, and fully mix,
Solvent then is drained, high-modulus agent is obtained final product.
The addition 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# asphalts+
The agent of 0.2wt% high-modulus) performance indications：
Table 1
Although embodiment of the present invention is disclosed as above, it is not restricted to listed in specification and implementation method
With, it can be applied to various suitable the field of the invention completely, for those skilled in the art, can be easily
Other modification is realized, therefore under the universal limited without departing substantially from claim and equivalency range, the present invention is not limited
In specific details.
