WATER SENSITIVITY OF ASPHALT-AGGREGATE MIXES: TEST SELECTION

摘要: The research presented in this report was conducted to identify the important factors influencing water sensitivity of asphalt paving mixtures, and develop a test method evaluate concrete mixtures for mix design. be performance related. A review current procedures revealed that no single suitable evaluation related field performance. Based on hypothesis air voids mixture may major source cause damage, system developed influence sensitivity. Environmental Conditioning System (ECS) used procedure includes specimen preparation; measurement permeability using air, water, or both; vacuum wetting; cycling at various temperatures; continuous repeated loading while monitoring resilient modulus after each conditioning cycle. Results four core indicated ECS can distinguish different materials their relative susceptibility. tentative is recommended.
