Ice and snow covering situation and the identical road surface of the volume of traffic are carried out the comparative observation same period (being respectively plain asphalt road surface and present embodiment rubber particle sheet pavement):
Road pavement is observed behind in December, 2003, in January, 2005 and December in 2005 three snow, and observation is divided into twice: being for the first time that snow stopped back 7 hours, is for the second time that snow stopped back 14 hours.
In December, 2003, external temperature was-8～-12 ℃ during observation experiment, and it is 13% that the plain asphalt road surface observes the road surface expose rate for the first time, and observing the road surface expose rate for the second time is 42%; It is 32% that the present embodiment rubber particle sheet pavement observes the road surface expose rate for the first time, and observing the road surface expose rate for the second time is 69%.
In January, 2005, external temperature was-10～-15 ℃ during observation experiment, and it is 19% that the plain asphalt road surface observes the road surface expose rate for the first time, and observing the road surface expose rate for the second time is 42%; It is 27% that the present embodiment rubber particle sheet pavement observes the road surface expose rate for the first time, and observing the road surface expose rate for the second time is 52%.
In December, 2005, external temperature was-9～-12 ℃ during observation experiment, and it is 3% that the plain asphalt road surface observes the road surface expose rate for the first time, and observing the road surface expose rate for the second time is 38%; It is 21% that the present embodiment rubber particle sheet pavement observes the road surface expose rate for the first time, and observing the road surface expose rate for the second time is 65%.
The experimental observation result is presented at the road surface of rubber particle sheet pavement under the envrionment temperature condition identical with traffic load effect number of times and exposes rate obviously greater than the plain asphalt road surface.The wheel traveling number of times is many more, and the degree of crushing of ice sheet is big more.
The comparative observation experiment finds that present embodiment rubber particle sheet pavement ice sheet crackle occurs early than the plain asphalt road surface in the environment little at snowfall, that ice layer thickness is little, envrionment temperature is higher relatively, under the effect of traffic load, and crack distribution density is greater than the plain asphalt road surface, but not obviously difference of road surface snow melting speed.Along with the increase of ice layer thickness, the reduction of envrionment temperature, the difference of plain asphalt road surface and present embodiment rubber particle sheet pavement is all the more obvious, crackle and broken phenomenon still can appear in the ice sheet of rubber particle sheet pavement, but crackle and broken phenomenon only appear at rubber grain around, and and plain asphalt road surface ice sheet is not seen any variation.
The comparative observation experiment finds that also present embodiment rubber particle sheet pavement ice layer thickness is inhomogeneous, and it is thinner relatively to be in rubber grain ice layer thickness on every side, and a little less than the cohesive force on ice sheet and road surface, is easy to mechanical removal; Plain asphalt road surface ice layer thickness is even, and the cohesive force on ice sheet and road surface is strong, is difficult to remove.
Under the situation big at snowfall, that road surface accumulated snow is thick, the accumulated snow of prevailing roadway is compacted, freezes under the driving loading action, though and the accumulated snow of present embodiment rubber particle sheet pavement through the traffic load effect but and do not freeze between the road surface, be block to distribute, can dispose at an easy rate.
Ice layer thickness is to the influence of the ice sheet percentage of damage on present embodiment rubber particle sheet pavement surface:
Under the certain prerequisite of wheel traveling number of times, envrionment temperature, ice sheet is thick more, ice face percentage of damage is low more, and it is low more that rate is exposed on the road surface.The wheel traveling number of times be 630 times, temperature for the relation curve of the ice sheet percentage of damage on present embodiment rubber particle sheet pavement surface under-1 ℃ the condition and ice layer thickness as shown in Figure 1.
Temperature is to the influence of the ice sheet percentage of damage on present embodiment rubber particle sheet pavement surface:
The road surface thickness of present embodiment rubber particle sheet pavement is 3cm, and the add-on of rubber grain is 4 weight parts, and the relation curve of the ice sheet percentage of damage on present embodiment rubber particle sheet pavement surface and temperature as shown in Figure 2 under the identical situation of other condition.
The crackle experiment:
The crackle experiment is carried out on three kinds of road surfaces, first kind is present embodiment rubber particle sheet pavement (add-on of rubber grain is 6 weight parts), second kind is to roll the rubber grain that a layer thickness is 4.75mm (rubber grain spill cloth density big) on the plain asphalt road surface, and the third is the plain asphalt road surface.The thickness on three kinds of test road surfaces all is 3cm, and experimental temperature is 0 ℃, and ice layer thickness is 2.5mm.25 times present embodiment rubber particle sheet pavements of experimental wheel traveling ice sheet begins to occur laterally and Circular Crack; 63 times second kind of road surface ice sheets of experimental wheel traveling are the Circular Crack that the center of circle distributes with the rubber grain, but do not occur transverse crack from start to finish; Crackle does not appear in the third road surface ice sheet all the time.
The accumulated ice of present embodiment rubber particle sheet pavement is ruined with the brittle rupture form, and accumulated ice is regarded as hard brittle material.Ice cracked when accumulated ice stress that wherein inner certain point produces under loading action or strain surpassed its ultimate strength or limit breaking strain, and crackle can be expanded rapidly with the continuation effect of load, causes the brittle rupture of ice.Experimental data shows stretching strain in the ice sheet of the road surface that rubber grain exists and tangential strain all greater than the limit breaking strain of ice, can assert that according to the brittle rupture theory of strength present embodiment rubber particle sheet pavement has destruction to ice sheet, can effectively suppress icy on road.
The adding of high-elastic characteristic rubber grain makes the bulk deformation ability of rubber particle sheet pavement significantly increase in the present embodiment rubber particle sheet pavement material; To exist huge modulus between rubber grain and building stones poor in addition, cause the icing situation of accumulated snow of rubber particle sheet pavement inhomogeneous, the bulk strength of ice and snow will reduce, under the driving loading action, be distributed in road surface rubber grain around very easily produce stress concentration, make the accumulated ice or the accumulated snow discontinuity of road surface, produce bigger distortion, and then the generation fragmentation is peeled off.In addition, the lubrication of ice crystal surface moisture film and because the viscosity degradation that the contact surface temperature rises and causes, make relatively sliding very easily takes place between ice and snow and the road surface, thereby effectively suppressed the bonding of ice and snow and road surface, thereby made rubber particle sheet pavement have good deicing performance.
