Description
Technical field
The present invention relates to road and bridge engineering technical field, more specifically, it be related to a kind of cold mixing cold laid asphaltic concrete and
Its preparation method.
Background technology
With national horizontal continuous improvement, in China, road construction cause is as the key project built, also quick
Development.Country is directed to developing transport development, although because have other modes of transportation now, and railway is also vigorously being sent out
Exhibition, still, highway communication is still one of important way of traffic.It is convenient and road traffic in connection with each city and area
The contact of people.Believe, even if economic growth rate is fast again, other modes of transportation develop swift and violent again, and road traffic is not
It can be eliminated in short time.
National development traffic engineering so energetically, also loses during it and leaves some problems, such as Water Damage, track
The problems such as, especially the fatigue cracking of bituminous paving, reflection crack, road surface accumulation permanent deformation problem annoying engineering skill always
Art personnel, and in China, because many influence factors, road just has such as track, pine soon after opening
The early damage of scattered, pit slot etc.In terms of the maintenance to road, the attention degree in China is not high, and there is very in China
More nervous engineering of more durations, these all make it that the quality of road is relatively low, will often be destroyed less than its service life,
Therefore the maintenance of road needs to strengthen.It is still stereotype maintenance technology but maintenance technology is not advanced in China.Although pass
The maintenance technology of system can conserve road, but as national income improves, vehicle also gradually increases, traditional maintenance
Technology specific aim is not strong, can not meet present road maintenance.Therefore, can more relax on road to travel people
It is suitable, safe, quick, and extend the service life of road, it would be desirable to constantly road is conserved.And ground according to pervious
Study carefully summary, cold mixing cold laid asphaltic concrete is used during the maintenance of road or Disease Processing, the anti-of road can be strengthened
Slip energy, and noise can be reduced, make driver safer, comfortable etc. in road up train.
The cold mixing cold laid asphaltic concrete research in China is started late, and technology is ripe not enough, and some of which product is excessive
Focused on pavement performance and have ignored construction workability, some then contrasts.It greatly limit cold mixing cold laid asphaltic coagulation
Use of the soil in road maintenance engineering, reduces the effect of maintenance.Therefore, there is an urgent need for system, deep cold to cold mixing

Emulsifying agent can change asphaltic nature, be mainly reflected in the following aspects：(a) effect of interfacial tension is reduced,
As emulsifying agent adds, the interfacial tension of water effectively reduces, make hydrone with bitumen particle very well wrap up in apply together with；(b) interface
The stabilization of electric charge, when making asphalt emulsion, is mutually wrapped up, emulsifying agent also can be corresponding by levigate bitumen particle and water
It is attached on bitumen particle, due to the effect of emulsifying agent intermediate ion, electric double layer is appeared in interfacial film row, and emulsifier molecules
With polar group and non-polar group, first layer is monolayer, since non-polar group is in the effect of this layer, makes this layer of band
There is opposite electric charge, itself and bitumen particle are close, and there is a natural attraction between the sexes so that the layer is attached on bitumen particle substantially, and than another
Layer is closer to bitumen particle, because of referred to herein as adsorption layer；The second layer is not stop to spread into water because of hydrophilic radical electric charge, formation
Diffusion layer, because after emulsifying agent attachment, all bitumen particles all carry like charges, and have above-mentioned described electric double layer to protect
Shield, so pitch-aqueous systems can be relatively stable；(c) effect of interfacial film, the drip that bitumen particle is formed after mutually being wrapped up with water
Green grass or young crops-aqueous systems, emulsifier molecules can also adsorb on the surface together with hydrone in this system, form interfacial film,
The interfacial film can play good barrier action, prevent bitumen particle from cohesion occurs to early with lotion adhesive bond, if occurring
More cohesion, will form " peeling " being commonly called as.And " peeling " will can not partly be waited due to demulsification too early and be stayed in aggregate blending
When, wrap up in deposited with gathering materials, and the quality of the asphalt of formation also can be poor., can be with and interfacial film has higher retractility
Expansion is also collapsible, can be very good protection bitumen particle.Interfacial film presence is also due to, cold-mix asphalt, which can just be stablized, to be deposited
Storage.
It is positive and negative when emulsified asphalt with positive charge and aggregate blending because surface of aggregate mostly carries negative electricity
There is a natural attraction between the sexes, and pitch and water oil particulate that water wraps up mutually can be caused together with gathering materials and wrapping up in apply well, to strengthen mixture
Bond effect.
