Technical field
The present invention has developed a kind of poriness road surface pellet antistripping test unit.Belong to the road engineering lab-size equipment.This test unit can be used for the test of porous asphalt pavement, surface, honeycombed cement concrete road surface pellet antistripping ability, and better pellet antistripping situation is shown on simulated roadway road under different pavement temperatures, load, vehicle running state.
Background technology
The poriness road surface, also claim the noise reduction drainage pavement, its skeleton gap structure is comparatively special, as a kind of functional road surface, can not only obviously reduce road rumble, alleviate the noise pollution that vehicle ' causes surrounding environment, and can get rid of in time, effectively road table ponding that rainfall brings, anti-harness the river float, phenomenon such as dazzle, improved the driving safety of vehicle greatly in the rainy day.Meanwhile, permeable, the gas penetration potential on ground improved because its inner connectivity gap has also been strengthened the underground reduction of rainwater and the water cycle on the face of land in the poriness road surface, for the ecosystem on every side provides good growing environment.
But, the voidage on this class poriness road surface is big (〉=18%) generally, bigger voidage makes that aggregate mainly is based on a contact in the ground surface material, cause the binding material consumption to reduce, cohesive force descends, make road table pellet be easy to generate to peel off under the effect of vehicle dynamic load and form the hole groove, to not only influencing the road surface function, serious meeting causes the destruction of pavement structural strength.
In sum, how to reduce poriness road surface pellet and peel off particularly importantly, the method for testing that proposes a kind of advantages of simple is a problem demanding prompt solution.Proving installation of the present invention can be simulated actual road environment, and each state of vehicle ' finally finds the key factor that influences poriness road surface particle antistripping ability, for the selection and the combination of material in the poriness Pavement Design process provides reliable basis.
Summary of the invention
The object of the present invention is to provide a kind of poriness road surface pellet antistripping test unit.Its equipment principle is simple, easy and simple to handle, test findings is directly perceived, can realize quick, objective, actual response poriness road surface pellet antistripping ability and influence factor thereof.The manufacturing expense of device is relatively low, use, safeguard simply, and this proving installation reliability is better, is beneficial to and applies.
Technical scheme of the present invention is achieved in that
This test unit has been installed reducing motor at the bracing frame right lower quadrant, reducing motor moves by the left and right sides power wheel that synchronous band drives the bracing frame middle part, driving-belt is provided with the test specimen box, test specimen top contact rubber wheel, rubber wheel pass through to be with synchronously the synchronizing wheel with on the servomotor to link to each other, be fixed in the wheel steering control gear on the back up pad, hydraulic jack links to each other with the bracing frame top by connecting struts.
Hydraulic Station is arranged at the bracing frame top, on top, the bracing frame left side visual control system is installed, lower left quarter has been installed temperature controlling machine.
Described wheel steering control gear is to connect tooth bar by hydraulic jack, and tooth bar one end connection gear constitutes.
The advantage that the technology of the present invention is outstanding is:
1) there is not unified test method to be used to estimate poriness road surface pellet antistripping ability as yet at present.
2) with the actual state good relationship, this test unit is simulated roadway road table pellet antistripping situation under multiple pavement temperature, load, vehicle running state better.
3) this experimental provision parameter is provided with simple and flexible, bond material test result analysis, finally can obtain influencing the principal element of road surface particle antistripping ability.
4) this testing apparatus is independent development, and principle is simple, makes and tests simply, and process of the test can realize omnidistance control and monitoring, and test findings is directly perceived.

Below in conjunction with accompanying drawing content of the present invention is described in further details.
Embodiment
With reference to Fig. 1, Fig. 2, shown in Figure 3, among the figure: 1, bracing frame; 2, temperature controlling machine; 3, synchronous pulley; 4, test specimen assembly section; 5, test specimen; 6, visual control platform; 7, view window; 8, connecting struts; 9, back up pad; 10, arm-tie; 11, servomotor; 12, bracing frame; 13, rubber wheel; 14 travel switches; 15, switch buting iron; 16, support rollers; 17, be with synchronously; 18, guide plate; 19, reducing motor; 20, Hydraulic Station; 21, pressing plate; 22, hydraulic jack; 23, synchronizing wheel; 24 are with synchronously; 25, tooth bar; 26, joint; 27, hydraulic jack; 28, gear.
This test unit has been installed reducing motor 19 at bracing frame 1 right lower quadrant, reducing motor 19 moves by the left and right sides power wheel 3 that synchronous band drives the bracing frame middle part, driving-belt 17 is provided with test specimen box 4, test specimen 5 tops contacts rubber wheel 13, rubber wheel 13 are by linking to each other with synchronizing wheel 23 on the servomotor 11 with 24 synchronously, be fixed in the wheel steering control gear on the back up pad 9, hydraulic jack 22 links to each other with bracing frame 1 top by connecting struts 8.Hydraulic Station 20 is arranged at bracing frame 1 top, on top, bracing frame 1 left side visual control system 6 is installed, lower left quarter has been installed temperature controlling machine 2.Described wheel steering control gear is to connect tooth bar 25 by hydraulic jack 27, and tooth bar one end connection gear 28 constitutes.
The present invention is in order to estimate poriness road surface pellet antistripping ability, by test simulation true road conditions, change different affecting factors, poriness road surface pellet antistripping capability analysis is estimated, can deeply be familiar with the basic law and the influence factor thereof of poriness road surface pellet antistripping ability deterioration, in conjunction with the starting material test result analysis, the real relation of setting up between environmental impact factor, material self property and the poriness road surface antistripping ability, thus foundation provided for the selection and the combination of poriness ground surface material.Therefore the present invention is a kind of method of testing of science practicality comparatively so far.The present invention can realize being with a wide range of applications the set goal quickly and easily.
