Scope
Scope: This standard is applicable to the resilience modulus testing and evaluation of clay, silt, sand-gravel soil, gravel soil, and other soil subgrades. The resilience modulus testing and evaluation of other subgrades can be carried out in accordance with this standard. Main technical content: Ball drop testing technology: Based on the Hertz collision theory, a rigid sphere is dropped from a certain height to collide with the soil subgrade. By measuring the acceleration-time process during the collision, the deformation characteristics of the soil subgrade can be calculated. The main contents include: General provisions, terms and symbols, basic requirements, testing requirements, testing preparation, testing implementation, and testing reports.
