Description
Technical field
The invention belongs to rut experimental technique field, especially relate to a kind of indoor rut instrument.
Background technology
Rut is the distinctive a kind of failure mode of bituminous concrete pavement, it is a kind of permanent deformation that produces under traffic load repeat function and weather combined factors effects such as (high temperature), show as and follow wheel mark generation banded groove longitudinally, the both sides of rut have projection deformation when serious, make the usability on road surface worsen more.The rut test is a kind of actual wheel load forms rut in the road surface walking engineering test method of simulating, from broadly, rut test, large-scale circular track test and straight way test are back and forth tested, rotated to indoor small-sized rut, all can think rut test category.The rut test is that a kind of evaluation asphalt is resisted plastic flow dynamic deformation effective methods under set point of temperature.The dynamic stability of rut test and the rut degree of depth of bituminous pavement have correlativity preferably, control the dynamic stability of asphalt rightly, and the energy making has the asphalt mat of certain resistance to permanent deformation.China with the wheel tracking test dynamic stability as asphalt high-temperature technology performance index, the technical requirement that " asphalt highway job specifications " (JTG F40-2004) stipulated the highway asphalt mixture dynamic stability.
Indoor wheel tracking test has become estimates the most frequently used test of mixture anti-rutting performance, and its advantage is: the load mode that applies has reflected the actual loading situation on the road surface, and instrument is relatively cheap, easy operating.The required device of indoor wheel tracking test is the rut instrument, it loads wheel and rolls sample repeatedly with certain load, speed under the uniform temperature condition, make sample under the reloading effect of wheel, produce densification, shearing, passing and mobile, thereby the generation rut rolls the development of rut in the process by continuous monitoring, obtains the distortion of 45min and 60min, formula calculates dynamic stability DS in accordance with regulations, in order to estimate the rutting resistance of asphalt.Test sample can be the plate test specimen that laboratory rolling compacting machine is made, and also can be that the diameter that road surface brill core obtains is the right cylinder sample of 200mm.The solid tyre that the loading wheel of present homemade rut instrument all adopts rubber to make mostly, diameter 200mm takes turns wide 50mm, and rubber bed thickness 15mm and round travel speed are 42 times/min, specifically have crank connecting link to drive experimental wheel and 2 kinds of modes of chain driving experimental wheel.
With regard to the present situation of present rut instrument, no matter use the right cylinder test specimen, the rectangular parallelepiped test specimen, although both rut degree of depth are variant, but test result can both be distinguished the anti-rut performance of compound preferably.When the performance to different compounds compares, need to use unified test specimen type.The difference that also has structure member between the rut instrument, such as, load wheel and mainly contain 4 types: steel wheel, steel wheel apply pressure to inflation sebific duct, pneumatic tyre and steel wheel and wrap up in rubber tire outward.The load level of all kinds of rut instrument differs greatly because loading wheel size is different with contact area, does not wait to several thousand Ns even tens Ns from the hundreds of ox.But the load of all kinds of rut instrument is all followed a cardinal rule: the effect of as far as possible simulating actual carload, so the loading wheel of all kinds of rut instrument and the footprint pressure of test specimen are all controlled at 0.6Mpa～0.9Mpa, this pressure has represented the ground connection pressure of a tire of single shaft two-wheel truck on the actual road surface, they all can distinguish the quality of asphalt mixture anti-rutting performance, and mostly better with the correlationship of on-the-spot rut performance.However, present rut instrument still has weak point, experimental wheel still exists all many-sides to need to improve, such as the adjustability of adjustability, load and the wheel load size of wheel travel speed, the simulation of climatic environment (can realize at present the simple situation of wetting of doing simulate) etc.And, the rut of generally acknowledging mainly is detrusion rather than compaction deformation both at home and abroad, the present employed rut instrument of China, from being subjected on the force mode, what test specimen bore in test process mainly is compressive stress, and corresponding distortion mainly is compaction deformation, this is because experimental wheel is driven by crank connecting link, non-driving wheel that only can simulating vehicle, and in the vehicle actual travel process, the shear action of driving wheel road pavement is bigger.
For the automobile of preposition rear-guard, the torque that engine sends is passed to rear wheel behind process clutch coupling, wheel box, universal joint, transmission shaft, main reducing gear, differential mechanism and the semiaxis successively, thereby rear wheel is called driving wheel.After driving wheel obtains torque, just give the acting force backward in ground, and therefore in the face of driving wheel produces a reacting force forward, this reacting force is exactly the driving force of automobile with making.The front vehicle wheel of automobile and power train generally do not have contacting directly on the power, therefore are called engaged wheel.That is to say, be rear wheel " promotions " front vehicle wheel in actual the advancing, and the drive vehicle advances.Thus, the load that applies of front and back wheel road pavement has very big difference.Automobile has states such as parking, travel, brake, turn on the road surface, along with the variation of automobile motion state on the road surface, the action direction of wheel load and amount of force also will change to some extent.When automobile is anchored on the road surface, generally only considers the acting force of wheel load road pavement, and in rut instrument design process, only consider the wheel load of automobile hind axle.When running car, the rear wheel road pavement is except having vertical force, and the horizontal tangential power that road pavement produces when also having wheel to rotate, horizontal tangential power are because the frictional resistance between tire and road surface causes.On the uphill way of mountainous area highway, under the situation of particularly travel heavy duty and overloaded vehicle, often the speed of a motor vehicle is slow, and the horizontal force that this moment, wheel acted on the road surface also is bigger.In addition, wheel also can produce horizontal force in braking procedure.Therefore, in the parking lot, the place of station, intersection, climbing lane, charge station and other traffic congestions, vehicle low running speed, it is bigger that the road surface is subjected to the vehicle horizontal loads, and the road surface is easier to produce destructions such as rut, hole groove.
