Description
Technical field
The invention belongs to bituminous material field, particularly, relate to a kind of environmental protection stable form asphalt mixed material modifier for snow melt and preparation method thereof.
Background technology
The primary requirement of road performance is security, and next is only the pavement performance of road.The various weather condition such as rain, snow, frost, mist all can serious harm Road safety.Especially in the severe winter that it is snowing in large flakes, road snow not only easily damages pavement structure, causes driving difficulty especially, and life inconvenience, road accident rate significantly increases.For this reason, there is different kinds of roads Snowremoval equipment, but these equipment ubiquities effort problem such as consuming time, and traffic congestion can be caused, the road is clear in impact.
Therefore, seeking Method and Technology from road self is the fundamental way solving pavement snow melting, and road construction, maintenance and research workers have studied the Method and Technology of various road snow already.Up to the present, these technology can be divided into two aspects, on the one hand, from the angle of highway layout, by steel material, wire, the materials such as electrode, road surface introduced by equipment and element, by the principle that electricity heats, the ground surface material of high-insulativity is made to have perception and the transfer capability of heat and electricity, electric power is converted into heat energy, heat energy by the contact surface of surfacing material and ice and snow to uploading to, after ice and snow absorbs heat, temperature raises gradually, road snow is melted and removes, this class methods snow melt efficiency is high, but by enforcement difficulty and cost high and power consumption larger, the pavement performance of road also cannot ensure, just in case occur causing road surface to occur other potential safety hazard and accident because of the use of such technology, it is the aim that road primarily requires that these class methods have just deviated from safety, on the other hand, from pavement material angle, according to the principle improving freezing point, by salts substances, as sodium hydroxide, sodium carbonate, villaumite (sodium-chlor, calcium chloride) etc. join in compound, under capillary pressure and vehicle roll effect, the inner salinity in road surface is separated out gradually, thus reduces the freezing point of road surface water, postpones road surface accumulated snow and freezes, by changing road surface physicals, reach the object of snow melt.These class methods are simple, but poor stability, reason is that these salts substances are subject to rainwash and run off in a large number.The inorganic salt run off are due to its corrosive nature, also the environment around road can be polluted, for this reason, people add " inhibiter " in villaumite Snow Agent, though inhibit corrosion to a certain extent, still have higher chlorine ion concentration, inhibiter mostly is nitrite, can only Reinforced Concrete Bridge be used for, and once go deep into soil meeting polluted underground water, so also not environmentally.
Unresolved the problems referred to above, the following patent documentation of current domestic main existence:
Application number: 201110456252.1, patent name: a kind of efficient snow melt meets modified asphalt mixture and preparation method thereof.Efficient snow melt meets modified asphalt mixture and comprises mineral aggregate 84.0-95.0 part, petroleum pitch 5.5-7.5 part, rubber grain 1.5-4.0 part, and chemical classes suppresses to freeze agent 1.0-4.5 part.Rubber grain and chemical classes are suppressed to freeze agent and add in compound by this invention, carry out the snow melt of opening ice on road surface from physics and chemistry two aspects.But this invention suppresses to freeze agent for the chemical classes reaching its effect and adopt, and is all buy from other manufacturers, virtually improves production cost.
In addition the material adopted in existing snow melt technology is mostly Nonrenewable resources, and along with the fast development of society and economy, resource is petered out, especially the consumption day by day of Nonrenewable resources, allows the mankind progressively be absorbed in without the desirable awkward situation of material.
Summary of the invention
The object of the invention is the shortcoming overcoming prior art, a kind of environmental protection stable form asphalt mixed material modifier for snow melt is provided.Described modifier components component property is stable, economic environmental protection, preparation process and Preparation equipment simple, use properties is stable, efficient, realize the science to waste and old resource, rationally, recycle and reuse effectively.Meanwhile, the present invention also provides a kind of preparation method of the environmental protection stable form asphalt mixed material modifier for snow melt.
