What are the geotechnical test test items for highway engineering? The
The main inspection items are: ① Tensile strength: In the tensile test, the maximum tensile stress of the specimen up to the fracture is the tensile strength, which is called tensile strength in academia. ② elongation: elongation, that is, the percentage of the ratio of the total deformation to the length of the original gauge after the tensile fracture of the specimen. ③ tear strength: it is a thin film or thin film tear resistance of a test method defined in a term. This method is a tear test performed on a special testing machine with a specimen with a predetermined gap. ④ bursting strength ⑤ thickness ⑥ per unit area quality ⑦ permeability coefficient: permeability coefficient, also known as hydraulic conductivity. In an isotropic medium, it is defined as the unit flow rate per unit of hydraulic gradient, indicating the ease with which the fluid passes through the pore skeleton.
Unit area weight or tensile strength, CBR burst strength, these two are the most basic, the other is not too important
