Abstract
The utility model discloses an adaptive ice breaking pavement of conductive bituminous concrete. The adaptive ice breaking pavement comprises a common concrete layer (4), a conductive bituminous concrete layer (3), an elastic layer (2) which is formed by bituminous concrete and rubber particles in a mixing manner, and a wearing layer (1) from bottom to top, wherein the common concrete layer (4) is in a saddle shape; the conductive bituminous concrete layer (3), the elastic layer (2) which is formed by bituminous concrete and rubber particles in a mixing manner, and the wearing layer (1) are arranged into a groove of the common concrete layer (4), so that the elastic deformation ability of the pavement is enhanced. By adopting the structure, the pavement contacting wheels slightly sinks when the wheels roll the pavement while an ice layer on the pavement cannot sink due to poor elasticity, and is crushed by the wheels, thereby achieving the self-stress ice breaking effect.
Description
Technical field
The utility model belongs to the highway construction of technical field of civil engineering, relates to a kind of snow-melting and ice-breaking road surface.
Background technology
At present northern China most areas and part southern area all generally face the Exploration on Train Operation Safety of winter after icy on road, the sudden snow disaster of nearly 2 years also makes this problem more outstanding, road is icing, wet and slippery very big on traffic safety impact, occurs that this situation will exist the potential safety hazard that consequence is very serious especially on speedway.The icing major measure of highway in China department reply road is passive type deicing, snow removing at present, as adopt snow removal with machine, salting opens ice etc., these measures not only need a large amount of human and material resources, and the negative effect of environment be can not be ignored, especially salting opens ice, and also very easily causes the corrosion damage of bridge.Prior art discloses a kind of conducting concrete layer highway, this road surface comprises conductive asphalt concrete layer, also comprise ordinary concrete layer, conductive asphalt concrete layer at least bottom surface He Liangge side is wrapped up by ordinary concrete layer, is provided with by many conduction reinforcing bars in conductive asphalt concrete layer.Wherein conductive asphalt concrete layer is born the function of conduction deicing or snow melting, and peripheral ordinary concrete layer plays heat preservation energy-saving effect, effectively reduces a large amount of losses of conductive asphalt concrete charging adstante febre heat, has improved heat insulation effect; Meanwhile, when peripheral ordinary concrete layer can also well prevent from conducting electricity reinforcing steel bars exposed by corrosion and avoid reinforcing bar conduction, electric current runs off.The method that this utility model provides need to consume a large amount of electric energy, and in remote, large-scale situation, efficiency is not high yet, causes a large amount of wastes of electric energy.
Summary of the invention
The deficiency existing for above-mentioned prior art, the technical problem to be solved in the present invention is: after sleety weather road freezes, in the situation that moisture conditions is less, the conductive asphalt concrete of prior art easily produces the phenomenon of waste of energy, in the situation that moisture conditions is larger, the problem of the larger electric energy of conductive asphalt concrete relative consumption of prior art.
For solving the problems of the technologies described above, the conductive asphalt concrete self adaptation of the present invention road surface of opening ice comprises ordinary concrete layer from bottom to top successively, conductive asphalt concrete layer (3), wherein the upper wearing layer (1) in addition of conductive asphalt concrete layer (3), is distributed with rubber grain in conductive asphalt concrete layer; Ordinary concrete layer (4) forms groove shapes, and conductive asphalt concrete layer (3) and wearing layer (1) are placed in the groove of ordinary concrete layer (4).
As the open ice preferred version on road surface of the self adaptation of the above-mentioned conductive asphalt concrete of the utility model, described elastic caoutchouc particle is bonded to entirety by bituminous concrete, thereby form separately elastic layer (2), be placed between conductive asphalt concrete layer (3) and wearing layer (1).
The bituminous concrete mixture that rubber grain is filled is the particle that waste and used rubber tyre is broken into definite shape and particle diameter, form with aggregate directly makes an addition in bituminous mixture, the novel high resiliency bituminous concrete mixture forming in order to replace part to gather materials, for paving engineering.
Described ordinary concrete layer (4) shape is preferably the shape of a saddle.
Compared with prior art, advantage of the present invention is:
1. the coefficient of thermal conductivity of ordinary concrete is lower, intensity is high, cost is low, and conductive asphalt concrete bond properties is good, especially lead a certain amount of rubber grain of middle interpolation and the mixed layer that forms has better elasticity at asphalt concrete, can, in the situation that not affecting conduction snow melt, realize both " combination among the strong ones ".
2. be very beneficial for the recovery of junked tire, there is very far-reaching influence for the recycling of old and useless article and the protection of environment.
3. open ice and improve the efficiency that opens ice from stress, save energy.
4. make the anti-rut performance of crack resistance at low-temperature and high temperature improve, road-ability is improved.
5. the absorptive capacity of road face of noise improves, and traffic noise obviously reduces.
In conjunction with conductive asphalt concrete technology, can make snow melt effect reach best, and almost pollution-free to environment, only need one-time investment, after completing, without dropping into again mint of money and manpower, in road construction from now on, have very large potentiality.
Brief description of the drawings
Fig. 1 is the open ice sectional drawing on road surface of the self adaptation of embodiment of the present invention conductive asphalt concrete.
Detailed description of the invention
Below in conjunction with embodiment, the present invention is described further.
As shown in Figure 1, the self adaptation of the conductive asphalt concrete of the embodiment of the present invention road surface of opening ice comprises the peripheral ordinary concrete 4 of the shape of a saddle, and the inside surrounds conductive asphalt concrete 3, and elastic layer 2, finally at elastic layer upper berth one deck wearing layer 1.
In this embodiment, peripheral ordinary concrete 4 heat preservation energy-savings, and play and prevent from conducting electricity reinforcing bar 5 and expose, corrosion; Meanwhile, parcel reinforcing bar, the generation of stray electrical current while preventing reinforcing bar conduction; In addition, also have the function of insulation, prevent a large amount of losses of conductive asphalt concrete charging adstante febre heat.Vehicular load is mainly born by conductive asphalt coagulation.Conductive asphalt concrete 3 and the elastic layer 2 of road-center are key positions, and after energising, conduction reinforcing bar 5 produces heat and makes road surface intensification, thereby dissolve the ice of road surface.In bituminous concrete, add rubber grain and form thinner one deck elastic layer, the elastic deformability on road surface is strengthened.In the time of wheel rolling road surface, the road surface that contacts with wheel can slight depression, and very poor cannot together depression of ice sheet elasticity on road surface just can be crushed by wheel, the ice crushing more easily melts under the heating of conductive asphalt concrete, thereby reaches the effect opening ice from stress.Wearing layer 1 can improve the durable and cling property on road surface, also can protect elastic layer and not be damaged.Adopt this embodiment, can better destroy layer icy on road, further improve road surface, sleet sky and form the travel safety after layers of ice.
By reference to the accompanying drawings embodiments of the present invention are explained in detail above, but the present invention is not limited to above-mentioned embodiment, in the ken possessing at affiliated technical field those of ordinary skill, can also under the prerequisite that does not depart from aim of the present invention, make a variety of changes.
