WebAug 10, 2024 · The resonant column test, Dynamic Shear Rheometer (DSR) and cone-and-plate method are the main methods used to study the damping characteristics of asphalt. The resonate column test is widely used to study the properties of asphalt in main roads, so the asphalt is usually mixed with sand and stone. The shear modulus is one of several quantities for measuring the stiffness of materials. All of them arise in the generalized Hooke's law: • Young's modulus E describes the material's strain response to uniaxial stress in the direction of this stress (like pulling on the ends of a wire or putting a weight on top of a column, with the wire getting longer and the column losing height),
