Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of mechanical equipment, in particular to a bituminous pavement surface texture multi-scale accelerated wear equipment and method. BACKGROUND

[0002] The bituminous pavement accelerated wear equipment is mainly used for emergency repair and rapid maintenance of highway infrastructure, can simulate and study the wear of the bituminous pavement in the actual use after rapid maintenance to evaluate the durability and skid resistance of the bituminous pavement. The skid resistance of the bituminous pavement is crucial to driving safety. With the increase of the number of motor vehicles on the road surface after the damage of the highway infrastructure, the study of the skid resistance of the road surface is particularly important. Limitations of the prior art: the traditional study of the skid resistance of the bituminous pavement mainly analyzes the skid resistance index of the skid resistance layer of the bituminous pavement or observes the attenuation of the skid resistance value of the bituminous pavement through the back-and-forth rubbing test of the track roller. However, these methods are difficult to simulate the contact and wear of the bituminous pavement in the actual driving process of the vehicle in one direction, and the attenuation law after different loading times has a large deviation from the actual situation. Development of the accelerated wear equipment: in order to more truly simulate the wear in the actual driving process, various bituminous pavement accelerated wear equipment has been developed. These equipment can simulate the one-way driving wear of the vehicle on the road surface and evaluate the attenuation process of the road surface under the cumulative number of wheel loads. 1. Bituminous pavement accelerated wear device with multi-field coupling: some advanced equipment can simulate the wear change law of the road surface under different temperature, humidity and ultraviolet light intensity conditions, and evaluate the wear resistance and durability of the road surface under the comprehensive environmental conditions. 2. Bituminous pavement three-wheel ring accelerated wear equipment based on active wheel driving: this is a new type of equipment, which includes a rack, a lifting assembly, a wheel set, a test piece placing platform and a pressure sensor. This equipment can more truly simulate the wear process of the tire and the road surface, and does not need to splice multiple bituminous test pieces to form a test area, but only needs a single bituminous test piece to start the test, which reduces the test cost and improves the test quality. 3. Water sand control device: some equipment uses sanding wear to accelerate wear, and through the weight sensor, the preset number counter and the digital time relay, the amount of wear sand and the sand falling period are accurately controlled, which greatly shortens the test wear period and effectively simulates the actual wear of the road surface. Accelerated wet wheel wear tester: for the detection of the skid resistance of the bituminous pavement, the accelerated wet wheel wear tester is developed to simulate the wear of the road surface after the completion of the construction in the long-term operation.

[0003] The traditional bituminous pavement accelerated wear equipment is difficult to move due to the problem of the equipment itself, can only simulate one wear state in one test, cannot perform on-site accelerated wear on the outdoor bituminous pavement, and cannot simulate the impact of the heavy vehicle bumping on the road surface, nor can it simulate the wear phenomenon of the vehicle transverse and longitudinal sliding on the road surface, so the simulation effect has a large error compared with the actual wear effect.
