Test method for semi-rigid base core sample compressive strength

Abstract

The invention relates to a test method for semi-rigid base core sample compressive strength. The test method comprises the following steps: selecting core drilling positions and sampling core samples; inspecting and screening the sampled core samples; carrying out end face treatment on the core samples, and performing humidity treatment on the core samples after end face treatment; carrying out tests of compressive strength; calculating the test data to obtain the compressive strength of the core samples, organizing and calculating the obtained all compressive strength, and obtaining the compressive strength value of each data group. The test method for semi-rigid base core sample compressive strength, provided by the invention, can solve the problems that in the prior art, as the compressive strength test method is not provided to test the semi-rigid base core sample on the road in the period of use, whether the semi-rigid base strength is qualified or not cannot be scientifically assessed and judged in the road overhaul design and construction, and further engineering measures cannot be adopted for reasonable treatment.

Description

technical field [0001] The invention relates to the technical field of traffic civil engineering, in particular to a strength test method, more specifically to a test method for the compressive strength of a semi-rigid base core sample. Background technique [0002] Compressive strength is one of the important strength indexes of road engineering materials. The compressive strength index is also an important mechanical index of highway base materials. The method of measuring the compressive strength is: follow certain technical procedures, make the sample under the condition of no reinforcement or restriction on the side, apply axial pressure until the sample is destroyed, and obtain the compressive strength of the sample. [0003] For the determination method of compressive strength index, "Highway Pavement Base Material Test Regulations" (JTJ057-85), "Highway Engineering Inorganic Binder Stable Materials Test Regulations" (JTJ057-94), "Highway Engineering Inorganic Binder...

Problems solved by technology

[0013] The technical problem to be solved by the present invention is to provide a test method for the compressive strength of a semi-rigid base core sample, which solves the problem of the lack of a method for testing the compressive strength of the semi-rigid base core sample on the road in the service period in the prior art. The problem that it is impossible to scientifically evaluate and judge whether the strength of the semi-rigid base layer is qualified during the design and construction of road overhaul, and then it is impossible to take engineering measures to deal with it reasonably
