Instruments and materials
Material testing machines, other pavement material testing equipment that can apply loads and test deformation can also be used, but all must meet the following conditions:
The large load should meet the requirements of not exceeding 80% of its measuring range and not less than 20% of its measuring range. 100kN and 100N division value should be used. With a spherical support, the indenter can move in close contact with the test piece.
With environmental insulation box, the temperature control accuracy is 0.5 ℃. When there is no environmental insulation box, the test room should be equipped with air conditioner, and the temperature control accuracy is 1.0 ℃.
It can meet the requirement of maintaining the loading rate of 2mm / min. The testing machine should have a servo system, and the speed is basically unchanged during the loading process. When the Marshall tester is used for manual control, the hand-cranking rate should be calibrated in advance to meet the requirement of 2mm / min loading rate.
Deformation measuring device
The upper and lower pressure plates are used for the compression test loading. The lower pressure plate has a base with a spherical surface. The pressure plate has a diameter of 120mm, and there is a shallow circumferential mark on the diameter of 102mm. There are column jacks on both sides of the lower pressure plate diameter line, and dial gauges are installed on both sides of the upper pressure plate diameter line. When the machine has the function of automatically measuring the vertical deformation of the test piece or automatically measuring the pressure and deformation curve of the test piece, it can be used directly without the need to additionally provide a deformation measurement device.
Dial indicator (1 / 1000mm), 2 pcs.
Constant temperature water tank: It is used for the insulation of the test piece, the temperature can meet the test temperature requirements, and the temperature control precision is ± 0.5 ℃. The liquid in the thermostatic water tank should be able to circulate continuously. The depth should be greater than the height of the test piece by 50mm.
Bench scale or balance: the sense is not more than 0.5g.
Thermometer: The division is 0.5 ℃.
