The invention, which relates to the technical field of experimental equipment, discloses a road material elasticity modulus and shear strength tester comprising a bracket, a rebound modulus measuringsystem, a shear testing system and an electric control system. The rebound modulus measuring system and the shear testing system are both arranged on the support. The rebound modulus measuring systemis sued for measuring the rebound modulus of a road material; the shear testing system is used for measuring the shearing strength of the road material; and the shear testing system and the rebound modulus measuring system are electrically connected with the electric control system. The electric control system is used for controlling whether the shear testing system and the rebound modulus measuring system are started or not, so that a defect of inaccurate experimental data caused by manual participation in the process of testing the elasticity modulus and the shear strength of the road material in the prior art can be overcome. Therefore, the manual participation in the experimental process can be avoided, so that the accuracy of the experimental data is improved.
Description
technical field [0001] The invention relates to the technical field of experimental equipment, in particular to a road material elastic modulus and shear strength tester. Background technique [0002] As one of the standard experiments stipulated in our country's regulations, the elastic modulus test and the shear strength test are the main methods to measure the mechanical properties of road materials. However, the experimental instruments used in the past have large errors in the experimental data caused by human operation, and the data errors caused by the performance problems of the instruments themselves, so the results of the experiments are not ideal. Contents of the invention [0003] The purpose of the present invention is to provide a road material elastic modulus and shear strength tester, to solve the problems in the prior art above, to avoid the defect of large error in experimental data caused by human operation, and to improve the accuracy of experimental da...
