Abstract

The invention discloses a multifunctional pavement strength tester which comprises a main body. A base is arranged at the bottom of the main body, a case is fixed to the top of the base, a workbench is connected to the top of the case, a baffle is arranged in the middle of the top of the workbench, a cover plate is arranged on the top of the baffle, a handle is arranged on the top of the cover plate, a pressure collector is arranged in the baffle, sleeve rings run through the two sides of the top of the worktable, screw rods are connected to the interiors of the sleeve rings, a fixed plate isarranged on the upper potions of the outer surfaces of the screw rods, a support rod is connected to the bottom of the fixed plate, a pressure sensor is fixed to the bottom of the support rod, a pressing plate is arranged at the bottom of the pressure sensor, and a control panel and a display screen are arranged on one side of the outer surface of the workbench. Data can be observed in real time,the accuracy of test data is improved, and the phenomenon that rubble splashes around when materials are crushed, and then staff around are hurt is prevented.

Description

technical field [0001] The invention relates to the technical field of pavement strength testing, in particular to a multifunctional pavement strength testing instrument. Background technique [0002] The pavement material strength tester is a multi-functional roadbed material experimental instrument, which is composed of a base, a gearbox, a column, a bracket, a motor, and an electrical switch. With the pavement material strength tester and other supporting fixtures, many tests can be carried out, such as the compressive strength, splitting strength, elastic modulus and other tests of cement lime stabilized soil, Marshall test of asphalt concrete, roadbed soil and various pavement materials Bearing ratio (CBR) test. [0003] The existing multifunctional pavement strength tester controls the speed of the pressure plate through the transmission to apply force to the pressure plate. Therefore, it is difficult to collect data in real time when testing pavement materials, so it...
