The main disadvantage of this kind of asphalt mixture rutting test machine is that the rubber wheel reciprocates on the surface of the asphalt mixture test piece, which is different from the one-way rolling in actual driving.
In addition, due to the limitation of the size of the large disc, the reciprocating distance of the rubber wheel is limited. Usually, only one asphalt mixture specimen can be tested in one test, and the anti-rutting ability of an asphalt mixture specimen needs to be tested for a certain number of times. 1 hour, under normal circumstances, only about 6 to 7 specimens can be tested per day
Secondly, due to the difference in ambient temperature fluctuations of different test pieces during the measurement process, it affects the comparability of test results between different test pieces.

Abstract
The invention discloses a tracking tester of indoor rotary tar hybrid material, which is characterized by the following: the rotary rack with rotary shaft is set on the floor of experimental table and in the environmental box; the top of rotary table pillar connects the experimental table panel; the speed adjustment motor contains electric rack, bearing support seat and heating pipe, which connects the rotary shaft through driving structure; the bottom of driving shaft is set on the bearing support seat; the rotary bearing is set between the rotary shaft and bearing support seat; the rotary bridge is set on the rotary shaft; the bearing sleeve and bearing are set between the rotary bridge and rotary shaft; rubber tyre column slide cylinder within at least one rubber tyre column is set on the rotary bridge; the weight block holder is set on the rubber tyre column to load the weight block and the rubber tyre is set on the bottom; the limitation column and at least two steel molds are set on the experimental table panel to assemble test piece of tar hybrid material with pad board among steel molds; the temperature controller is set on the exterior of environmental box. The invention shortens the test time and improves the efficiency, which can be used in the tracking-proof experiment of tar hybrid material pavement.
Description
technical field [0001] The invention belongs to the technical field of paving and repairing machines, tools or auxiliary equipment for pavement of roads or other similar structures, and in particular relates to an indoor rotary asphalt mixture rutting testing machine. Background technique [0002] At present, asphalt mixture is mainly used for road pavement at all levels at home and abroad. Asphalt mixture is mainly composed of asphalt and aggregate. Asphalt mixture is an elastic, viscous and plastic material. When the rutting is serious, it will not only affect the comfort of driving, but also bring safety hazards to high-speed driving. Rutting is the main damage form of asphalt pavement at present. One, the highway department will spend a large amount of maintenance and repair funds for this every year. [0003] Asphalt content and aggregate ratio in asphalt mixture pavement are important factors affecting rutting. Under the same use environment and traffic volume, a reas...
