| titleOfInvention | Device and method for measuring anti-wear performance of aggregate |
| abstract | The invention discloses a device and a method for measuring the anti-wear performance of aggregate, belongs to the technical field of road engineering, and solves the problem of poor accuracy of the conventional measuring device. The tire rotating disc type power transmission device comprises a base and a motor, and further comprises a rotating column, fixing columns, a tire rotating disc, a first grid and a second grid, wherein the rotating column is connected to an output shaft of the motor, the tire rotating disc is arranged on the rotating column, the fixing columns are arranged on the base, the first grid is supported above the tire rotating disc through the fixing columns, aggregate is loaded on the first grid, the second grid covers the aggregate, and the upper ends of the fixing columns are connected with locking nuts through threads. The determination method comprises the following steps: fixing the vehicle tyre on the tyre turntable; pouring aggregate on the first grid, covering the second grid on the aggregate, and screwing down the locking nut; adjusting the height of the aggregate by screwing the fixed column to enable the aggregate to be in contact with the vehicle tire; starting the motor, rotating the vehicle tyre and abrading the aggregate. The invention can accurately measure the abrasion resistance of the aggregate. |
