Description
Technical Field
The invention relates to the technical field of pavement, in particular to a self-adaptive anti-icing pavement.
Background
Winter roads, bridges and some special road sections, such as: under the conditions of sudden air temperature drop, humid air and large fog, the road and bridge surfaces are easy to form ice layers to cause sudden traffic accidents or road and bridge traffic jam and the like, which always troubles the traffic departments of all countries in the world. The direct economic losses due to various abnormal conditions of winter climate change and snow (frost) icing on road surfaces of roads and bridges can reach billions of dollars each year. Therefore, the effective treatment of the snow (frost) on the road surface and the road maintenance in winter are highly regarded by various countries, and a great deal of research is carried out for the effective treatment and the road maintenance in winter, and various methods for inhibiting the snow on the road surface are explored. These methods are classified into two major categories, passive and active.
In the method for passively suppressing the snow on the road surface from being frozen, it is most known to spread a snow melting agent after snowing, and then passively spread a chemical agent on the road surface to lower the melting point of the snow and ice, so as to melt the snow and ice, thereby making it clear of the snow and ice. The ice and snow melting agent commonly used at home and abroad mainly comprises salts and alcohols. The alcohols have the phenomenon of anti-icing, the effect is not good, and the comprehensive cost is greatly increased; the salts are corrosive and easy to corrode and destroy road structures and motor vehicles, and also pollute the land, water and atmosphere and destroy the ecological environment. Still other passive methods are manual cleaning methods, spreading sandstone fly ash materials and mechanical cleaning methods. The ice and snow can be melted by utilizing the heat generated by hot water, terrestrial heat, gas, electricity and the like, and the method is also one of the technical methods for passively melting the snow, but the energy consumption is too large, and the engineering technology is difficult to implement.
The technology for actively inhibiting ice and snow on the road surface mainly comprises a self-stress elastic road surface pavement technology, a conductive pavement ice and snow melting technology and an energy conversion type ice and snow melting technology (such as industrial electric energy, solar energy, geothermal energy and the like).
The self-stress elastic pavement paving technology is an active ice breaking technology which is formed in recent years, and by utilizing the characteristic that the local deformation of the material of the ice breaking pavement layer is stronger, ice and snow are broken and melted through the self-stress generated under the action of external load during pavement paving, so that the accumulated snow and ice on the pavement are effectively inhibited, the anti-skid performance of the pavement under the condition of low-temperature snowfall in winter is improved, and the driving safety of a running vehicle after the pavement is frozen in winter is ensured.
Chinese patent publication No. CN101219870A (published as 2008/7/16) discloses a rubber particle asphalt pavement material and a method for paving a rubber particle asphalt pavement, wherein a certain amount of rubber particles are added to the asphalt pavement material, so that the deformation capability of the pavement can be effectively improved, the adhesion state of ice and snow to the pavement can be improved, and snow and ice on the pavement can be effectively inhibited by self-stress under the action of vehicle load. However, the rubber particles have large elastic deformation capability and are not obviously embedded and extruded with aggregates, so that the problem of loosening of the mixture is easily caused, and the durability of a pavement structure is influenced.
Chinese patent publication No. CN102432228B (published as 2012, 5, month and 2) discloses a pavement self-icebreaking anti-skid paving layer mixture and a preparation method thereof, wherein rubber particles, a polyurethane adhesive, fibers, a hydrophobic material and a drier are mixed in proportion to prepare the pavement self-icebreaking anti-skid paving layer mixture, and the pavement self-icebreaking anti-skid paving layer mixture is paved on a pavement, so that the anti-skid performance of the pavement under the low-temperature snowfall condition in winter is improved, and the pavement is simple to pave and has strong durability. Although the cementing material and the aggregate have strong caking property in the mixture, the pavement formed by the mixture has a plurality of gaps, and in cold winter, moisture is easy to permeate into the gaps and freezes and expands under the low-temperature condition, so that the pavement is loose and damaged.
