The importance of laboratory tests for predicting performance of asphalt mixtures
Аннотация
Rutting on an asphalt surface is rarely a sudden defect. In most cases, it is the visible outcome of permanent deformation that accumulates over time typically at high service temperatures and under heavy traffic moving at low speeds. The consequences go beyond durability. Rutting reduces ride comfort and the perception of safety, while the lateral lift that forms along the wheel path can hinder drainage and contribute to aquaplaning, creating serious road safety concerns.
This is why laboratory testing remains a practical foundation for predicting how asphalt mixtures will behave in service. Over the past decades, performance-oriented design and simulative laboratory methods have been developed to better connect mixture properties with real pavement behavior. The Superpave method addressed rutting resistance as a central performance requirement, and the Hamburg Wheel Tracking Device (HWTD) has become one of the most widely used tools to evaluate both permanent deformation and moisture damage from water.
