Alkene ether infiltrates into bituminous concrete, so that casein is distributed more uniform in bituminous concrete, and then is conducive to casein
Preferably in conjunction with the metal ion in bituminous concrete, so that when moisture penetration to any position of bituminous concrete, junket egg
Bai Junke plays a role, to guarantee to improve the effect of bituminous concrete compression strength, so that asphalt concrete pavement is anti-
Compressive Strength is higher, is easy to keep surfacing, cracky, service life is not longer.
The present invention is further arranged to: the vinyl acetate content in the acrylic emulsion is 70%.
By using above-mentioned technical proposal, the acrylic emulsion for being 70% by using vinyl acetate content is conducive to mention
The bonding strength of high acrylic emulsion and other components has so that each component is not easy the phenomenon that bleeding or isolation occur
It is uniformly dispersed conducive to each component, and then is conducive to improve the stability of bituminous concrete.
The present invention is further arranged to: the bituminous concrete further includes the component of following mass fraction:
2-3 parts of water-reducing agent.
By using above-mentioned technical proposal, the dosage of water in bituminous concrete, section can be effectively reduced by the way that water-reducing agent is added
About resource.
The present invention is further arranged to: the water-reducing agent is the horizontal sour calcium of lignin.
By using above-mentioned technical proposal, since the binding ability of casein and calcium ion is stronger, pass through the horizontal acid of lignin
Calcium can make full use of casein in conjunction with water-reducing agent as water-reducing agent, so that water-reducing agent follows casein to disperse, so that subtracting
Aqua dispersion efficiency is higher and more uniform, so that reducing preferable with the effect of water.
The present invention is further arranged to: the bituminous concrete further includes the component of following mass fraction:
2-3 parts of lotus leaf powder.
The hydrophobicity of bituminous concrete is effectively improved, and then make by the way that lotus leaf powder is added by using above-mentioned technical proposal
The waterproof performance for obtaining asphalt concrete pavement is preferable, so that moisture is not easy to penetrate into bituminous concrete internal structure, reduces
Destruction to bituminous concrete internal structure.
The present invention is further arranged to: the bituminous concrete further includes the component of following mass fraction:
3-5 parts of glass fibre；
1-3 parts of polyacrylonitrile.
Made by using above-mentioned technical proposal by the way that glass fibre and polyacrylonitrile is added with reinforcement bituminous concrete
It is not easy to crack to obtain bituminous concrete, improves stability.
The present invention is further arranged to: being filled substrate in the step S3 and is used natural rock stone.
Natural rock stone is utilized by natural rock block support asphalt concrete pavement by using above-mentioned technical proposal
Between gap play the role of preferable permeable so that the water permeability of asphalt concrete pavement is preferable, be not easy ponding.
The present invention is further arranged to: the preparation method of the bituminous concrete the following steps are included:
A. mixed Portland cement and water are to form cement grout；
B. pitch is added in cement grout and stirs evenly to form pitch slurries；
C. sand, stone, acrylic emulsion, casein and fatty alcohol polyoxyethylene ether are added in pitch slurries and stirs equal
It is even to form bituminous concrete.
By using above-mentioned technical proposal, dripped by being first stirred portland cement and water with being stirred in cement grout
Blueness, so that pitch is easily dispersed, stirring is convenient；By formed pitch slurries after be added sand, stone, acrylic emulsion, casein with
And fatty alcohol polyoxyethylene ether makes each material dispersion more uniform, reduce causes pitch to be difficult to disperse after solid matter first is added
The case where, so that asphalt concrete quality is more preferably.
In conclusion the invention has the following advantages:
1. by the way that casein is added in bituminous concrete, using the calcium binding in casein and portland cement, with
In intermolecular formation cross-linked network, so that molecular motion is further obstructed, and then improves the compression strength of bituminous concrete, mention
The high structural stability of bituminous concrete；
