摘要

The unconfined compressive strength test is a mandatory experiment for cement stabilized material (CSM) of highway design and construction. Currently, the test can be completed with the cooperation of various equipment such as reaction frame, lifting jack, demoulding device and press machine. In order to improve the testing efficiency and precision, the research team designed an assembly multi-function unitized testing machine (MUTM) that integrated the four devices. The MUTM consists of five parts: Frame System, Reaction frame system, Power system, Function conversion system and Electrical system. The MUTM makes the manufacturing, demoulding and strength testing of the unconfined compressive strength test completed on one test equipment. After testing, the testing efficiency and stability of the equipment are increased by more than 50% and 14%. While meeting the specification requirements, the testing efficiency is significantly improved.
