沥青混合料单轴压缩试验机本方法适用于直径100mm±2.0mm,高100mm±2.0mm的沥青混合料圆柱体试件。

仪具与材料

材料试验机,其它可施加荷载并测试变形的路面材料试验设备也可使用,但均必须满足下列条件:

大荷载应满足不超过其量程的80%,且不小于量程的20%的要求,宜采用100kN,分度值100N。具有球形支座,压头可以活动与试件紧密接触。

具有环境保温箱,控温准确度0.5℃。当缺乏环境保温箱时,试验室应设置空调,控温准确度1.0℃。

能符合加载速率保持2mm/min的要求。试验机宜有伺服系统,在加载过程中速度基本不变。当采用马歇尔试验仪手动控制时,应事先校正手摇速率,以达到2mm/min加载速率的要求。

变形量测装置

 抗压试验加载用上下压板,下压板下有带球面的底座。压板直径120mm,在直径102mm处有一浅的放置试件的圆周刻印。下压板直径线两侧有立柱顶杆,上压板直径线两侧装有千分表架,表架中间与顶杆中间位置一致。当使用机具有自动测定试件垂直变形或自动测记试件的压力与变形曲线功能时,可以直接使用,不必另外配备变形量测装置。

千分表(1/1000mm),2只。

恒温水槽:用于试件保温,温度能满足试验温度要求,控温精密度±0.5℃。恒温水槽的液体应能不断循环回流。深度应大于试件高度50mm。

台秤或天平:感量不大于0.5g。

Asphalt mixture uniaxial compression tester This method is suitable for asphalt mixture cylinder test pieces with a diameter of 100mm ± 2.0mm and a height of 100mm ± 2.0mm.

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 ℃.
