Abstract
A kind of preparation method the invention discloses highway with cement pitch concrete, emulsified after first silane coupler KH 570 is mixed with matrix pitch high temperature, then tetraethyl orthosilicate is added dropwise and carries out solgel reaction in situ, by obtained modified emulsifying asphalt and rosin milk, gather materials, mixed in glass fibre, be molded, conserve, obtain highway cement pitch concrete.Highway cement pitch concrete prepared by the present invention has good interface binding intensity, and uniformity is good, and durability is high, and overall performance is strong.
Description
Technical field
The present invention relates to building material technical field, more particularly to a kind of preparation side of highway cement pitch concrete
Method.
Background technology
At present, China's road surface types are basically divided into cement concrete pavement and the class of asphalt concrete pavement two.Cement mixes
Solidifying soil surface bearing capacity is strong, high-temperature stability is good, weatherability, excellent durability, but cracking phenomena easily occurs, and ties up
Difficulty is repaiied, road-ability is poor；Asphalt concrete pavement surface smoothness is higher, and has vibration-damping function, and comfortableness is preferable,
But, easy craze and transfiguration sensitive to water and temperature.Cement emulsified asphalt concrete is in cold mixing Emulsified Asphalt Mixture parent
Middle incorporation cement semi-rigid pavement material formed through cold mixing, cold-application, the advantages of having flexible material and rigid material concurrently, can
Improve the performance on road surface.However, because the adhesiveness of emulsified asphalt and building stones is poor, interface binding intensity is inadequate, causes
Current cement-emulsified cement pitch concrete material still has the problem of bulk strength is inadequate, it is necessary to make improvements.
The content of the invention
A kind of the defects of the object of the invention is exactly to make up prior art, there is provided high intensity highway cement pitch coagulation
The preparation method of soil.
The present invention is achieved by the following technical solutions：
A kind of highway preparation method of cement pitch concrete, comprises the following steps：
（1）1-2 parts by weight Silane coupling reagent KH-570 is added in 30-40 parts by weight pitches in 110-160 DEG C of mixed processing 5-
10min, then add 1.5-2.5 parts by weight Emulsifier, 0.1-1 parts by weight stabilizer is formulated with 25-35 parts by weight water
40-80 DEG C in mixed solution, 1500-2000r/min high-speed stirreds disperse 5-10min, then pH is adjusted to 8-8.5, is slowly added dropwise
3-5 parts by weight tetraethyl orthosilicate and the stirring reaction 12-24h under normal temperature, obtain modified emulsifying asphalt；
（2）500-800 parts by weight are gathered materials, 10-20 parts by weight of glass fiber and 30-40 parts by weight water mixing 1-2min,
Then 5-10 parts by weight rosin milk and step are added（1）Obtained modified emulsifying asphalt mixing 0.5-1min, through overmolding, support
Shield, obtains highway cement pitch concrete.
The anionic emulsifier is in neopelex, sodium lignin sulfonate, lauryl sodium sulfate
It is one or more of.
The nonionic emulsifier is the one or more in NPE, Tween-80, Arlacel-80.
The length of the glass fibre is 2-4mm.
The solid content of the rosin milk is 50-55%.
It is described that to gather materials for crushed granite, its nominal maximum particle diameter be 9.5mm.
It is an advantage of the invention that：
The present invention is emulsified after first Silane coupling reagent KH-570 is mixed with matrix pitch high temperature, and tetraethyl orthosilicate is then added dropwise
Sol gel reaction in situ is carried out, inorganic nano layer is introduced on emulsified asphalt surface, by obtained modified emulsifying asphalt and rosin
Emulsion, gather materials, mixed in glass fibre, is molded, maintenance, obtaining highway cement pitch concrete.The present invention passes through nanometer two
Silica carries out surface coating modification to emulsified asphalt, enhances-the strength and stability of asphalt interface network structure that gathers materials, pine
Fragrant emulsion improves the-interfacial adhesion of pitch that gathers materials, and glass fibre can improve the overall toughness and tensile strength of concrete, from
And the highway cement pitch concrete for making to obtain has good interface binding intensity, uniformity is good, and durability is high, globality
Can be strong.
Embodiment
A kind of highway preparation method of cement pitch concrete, comprises the following steps：
（1）1 parts by weight Silane coupling reagent KH-570 is added in 30 parts by weight 70# pitches in 110 DEG C of mixed processing 5min, then
Add in the mixed solution that 1.5 parts by weight Emulsifier, 0.1 parts by weight stabilizer and 25 parts by weight water are formulated 40 DEG C,
1500r/min high-speed stirreds disperse 5min, then pH is adjusted into 8, and 3 parts by weight tetraethyl orthosilicates are slowly added dropwise and are stirred under normal temperature
12h is reacted, obtains modified emulsifying asphalt；
（2）500 parts by weight are gathered materials, 10 parts by weight of glass fiber and 30 parts by weight water mixing 1min, then add 5 weight
