Description
Technical field
This practicality relates to application and the technical field of construction of the highway, particularly relates to a kind of dress recovering bituminous paving skid resistance
Put.
Background technology
The antiskid performance of asphalt highway is the important indicator determining traffic safety, is the most basic requirement of road pavement,
When vehicle is run at high speed on highway, if the frictional force between tire and road surface is the least, particularly road surface is under damp condition,
Moisture film has deadened contacting of tire and road surface, makes frictional force be destroyed, and causes tire to produce water drift on road surface when high speed existing
As, making automobile brake lengthening distance, if emergency turn simultaneously or braking, being more easy to direction finding smooth, so that being susceptible to vehicle accident.
For ensureing the antiskid performance on road surface, China is correlated with bituminous pavement design for highway specification and acceptance criteria to reflection pavement skid resistance condition
Index coefficient of friction (or cornering ratio), construction depth all make clear and definite regulation.Therefore, reach acceptance requirement and pay
Use bituminous paving be think can be safely controllable driving road surface.
A large amount of field datas show, the size of coefficient of friction is dependent firstly on the roughness of road table, and the roughness of road table is then
Close grain and open grain two aspect by road table are constituted.Close grain refers to the texture (i.e. the rugosity of building stones itself) of stone surface.
Open grain is then uneven formed texture, i.e. construction depth between the building stones exposed by facing surface, and it makes tire
The contact of rubbing action is maintained with asphalt surface course.And when road speed is higher, for coefficient of friction, then by open grain
Play a major role.Speed is the highest, the biggest for the open grain degree of depth required for obtaining certain coefficient of friction.
In order to make road surface keep good antiskid performance and ruggedness, engineering circles ceaselessly explores new technique, new material, new
Method, such as rational mixture structure, high performance asphalt material etc..But along with the driving effect accumulated over a long period, bituminous paving
The decay of antiskid performance is inevitable.Mainly show themselves in that one is that road surface is compacted, in road surface under driving effect further
The asphalt mastic in portion is extruded to surface, fills the groove between rubble material, forms smooth surface, also forms bellding, make time serious
Construction depth is become to decline；Two is the bellding that mass defect causes, and this may often be such that because match ratio is unreasonable or technology controlling and process etc. is former
Bitumen content because causing is too much, just causes bellding at the pavement usage initial stage.
At this moment, construction depth diminishes and even disappears, roughness degradation, thus causes skid resistance can meet road surface
The safety requirements of driving.In order to keep the traffic safety on road surface, relevant departments have to carry out overlaying road crust and process.This
Kind of way owing to fund input is big, pavement structure changes greatly, the most preferable treating method.
If in view of there being a kind of equipment to be disposed by unnecessary asphalt mastic (bellding) between the building stones of former road surface, retained simultaneously
The rubble material on road surface, increase the roughness on road surface, thus recover the antiskid performance on road surface, it is to avoid overlays surface layer again, and this is not
Lose as a kind of simple, economic way.

Fig. 2 is this utility model structural representation front view.
Detailed description of the invention
1,2 this utility model is described below in conjunction with the accompanying drawings.
Fig. 1, a kind of device recovering bituminous paving skid resistance shown in 2, including automobile 1, fixing device 2, driving means,
Steel wire roller 3 and brush roll 4, described fixing device is connected to automotive front end by fulcrum 5, connects bottom described fixing device 2
Steel wire roller 3 and brush roll 4, described steel wire roller 3 and brush roll 4 are positioned at automobile 1 front end side by side, described fixing device 2 are provided with
Driving means, described driving means is connected with steel wire 3 roller, brush roll 4.
Described driving means includes motor the 6, first drive 7, belt 8 and the second drive 9, and described motor 6 is positioned at solid
Determining on device 2, described motor 6 is connected with the first drive 7 by belt 8, and described first drive 7 is by belt 8 and second
Drive 9 connects, and described first drive 7 connects steel wire roller 3 by power transmission shaft 10, and described second drive 9 passes through power transmission shaft
Connect brush roll 4.
Including cylinder 11, described cylinder 11 is connected with fixing device 2.
Described steel wire roller 3 includes that steel wire, described tensile strength of wire are not less than 1200MPa, and sectional dimension is 1.5-
6.0mm。
In described steel wire roller 3, steel wire spacing distance is 5-20mm；The a length of 5-30cm of steel wire, steel wire in described steel wire roller
For matrix or quincunx spread geometry.
Motor high-speed rotation drives steel wire roller and brush roll to rotate so that steel wire roller connects with asphalt floor 12 rolling friction
Touch, thus remove rubber cement unnecessary between the building stones on asphalt floor 12 or road surface bellding, retain the building stones knot on former road surface simultaneously
Structure, is removed the bellding degree of depth and can be adjusted the frictional force of steel wire roller and asphalt floor by cylinder control pressure, thus control mill
The degree of depth removed and intensity, automobile promotes this device to be moved along, so that the efficiency removing asphalt floor is more increased, for protecting
The steel wire of card steel wire roller has the serviceabilities such as good intensity, elasticity and toughness, employs the design of specific steel wire and roller, steel
