Description
Technical field
The utility model relates to a kind of checkout equipment of ground surface material, is specifically related to a kind of ground surface material and quickens the abrasion instrument.
Background technology
The cling property of bituminous pavement is the key factor that influences traffic safety.Because pavement construction is in open-air atmosphere after finishing for a long time, its cling property is decayed inevitably along with vehicular load and climatic environment effect.In order to address the above problem, current road worker has mainly taked dual mode: a kind of is to use good the gathering materials or use the grating type that can keep good cling property relatively for a long time of abrasion resisting performance in Asphalt Mixture Design; Another kind is the cling property on long term monitoring road surface, in case cling property does not satisfy the requirement of setting value, promptly road pavement is heavily spread to improve its cling property.The enterprising line correlation experimental study on actual road surface verifies that some gather materials, novel mix type or obtain the critical level of antiskid value not only spended time is long, and spending is big.In addition, the maintenance of surface slip-stick artist determines that by an attenuation process at the anti-skid performance of road surface of labour suitable maintenance scheme also can run into many difficulties if want.Therefore, carry out fast the pavement skid resistance condition decay and just seem very important indoor.
In pavement skid resistance condition test, full-scale test can be simulated actual driving effect well, and the measurement of antiskid index can use full-scale plant, and this is that any other simulation laboratory test can't be compared.But this type of test is costly, and some test periods are longer relatively, as the NCAT test track.Britain's accelerated polishing machine and similar instrument are the testing equipments that to gather materials the polishing performance and develop in order to estimate, and its test condition also is not suitable for asphalt, and the measurement means of antiskid index mostly has certain limitation.Although domestic wheel tracking test instrument simulation test has advantages such as easy to use, that temperature load can be regulated, its shortcoming also can't be avoided: wheel tracking test wheel is straight reciprocating motion, the difference of having travelled of this and actual vehicle; Because the effect width limited (5cm) of wheel tracking test instrument can run into no small challenge when measuring the antiskid index.
For domestic and international existing small-sized indoor asphalt pavement skid resistance decay simulated test facility, simulated conditions also need further checking with the goodness of fit of reality and the stability of testing equipment, and in addition, equipment cost is higher, size is bigger than normal, and the measurement of especially antiskid index remains in certain limitation.
The utility model content
The purpose of this utility model is the deficiency that exists at prior art, provides a kind of volume ground surface material little, stable and reliable for performance, easy to install to quicken the abrasion instrument.
The technical solution of the utility model is: a kind of ground surface material quickens the abrasion instrument, on comprising frame and being arranged on frame and the motor that is connected with control gear, motor connects the axis that vertically is provided with by speed adjusting gear, it is characterized in that: described axis and horizontally disposed load disk flexibly connect, be movably set with on the load disk and transfer the lotus disk, the bottom of load disk is provided with a plurality of rubber wheels that are used to roll test specimen; The frame that is positioned at the axis both sides is provided with the infrared transmitting device that is used to write down revolution, and infrared transmitting device is connected with control gear by lead; The bottom of described frame is provided with the sparge pipe that is used for to the test specimen watering, and the bottom of frame is provided with the trip bolt that is used for fixing test specimen; Valve is housed on the sparge pipe, and valve is connected with described control gear.
The utility model compared with prior art has the following advantages: the rotating speed of the utility model rubber wheel, load are adjustable, are convenient to simulate different road traffic conditions; The utility model is not only applicable to the laboratory, and can use on the actual at the scene road surface.
