SYD-0755 Load Wheel Tester Introduction: The load wheel tester is designed and manufactured in accordance with the requirements of T 0755-2011 "Load wheel sand adhesion test for slurry mixtures" in JTG E20-2011 "Test Code for Asphalt and Asphalt Mixtures in Highway Engineering" of the Ministry of Transportation of the People's Republic of China. It is suitable for controlling the upper limit of asphalt content in slurry mixtures and determining the * asphalt content of slurry mixtures together with wet wheel wear tests. Features: 1. This instrument is a floor standing structure, and its structural design, specifications and dimensions of the testing instruments all comply with the requirements of T0755 standard. The design is novel, the structure is reasonable, and it is easy to use. 2. The mechanical transmission part is designed with safety protection devices to prevent accidental injury to the operator, ensuring safety and reliability. 3. The compaction frequency during the experiment is pre-set by the operator, and the instrument automatically counts during operation until the count value equals the set value, and the instrument stops working. Technical parameters: Rolling frequency: 44 times/min ± 1 time/min; Crank radius: 152mm ± 2mm; Rubber wheel size: diameter 76.5mm ± 1mm, width 26.0mm ± 1.0mm; Rubber wheel hardness: between HRC60 and HRC70; Rubber wheel loading weight: The total weight of the car when placed horizontally is 56.7 kg ± 0.5 kg; Trial mold: available in 6.4mm and 12.7mm thicknesses, selected as needed, with internal dimensions of 50mm x 380mm Sand frame: The internal dimensions are 355.0 mm in length x 38.0 mm in width x 0.5 mm in thickness; Steel cover plate: size 353 mm in length x 36 mm in width x 3 mm in height; External dimensions: 1400mm x 260mm x 450mm (length x width x height); Working power supply: AC three-phase 380V/50Hz, motor power 550W.
