Description
This study delves into a novel area of research, exploring the implications of zeolite in Warm Mix Asphalt (WMA) on compactability indices and moisture damage. The investigation focuses on the impact of aging time and workability properties on WMA mixtures, utilizing compactability to determine production temperatures. Two distinct approaches were employed to assess workability properties: compatibility indices and moisture sensitivity testing. Four types of zeolites (Aspha-min, ZP-4A, Type A, and Natural) were utilized. The results of compactability indices following a two-hour aging period indicate that zeolite can enhance workability even with reduced mixing and compaction temperatures. Furthermore, the moisture sensitivity test revealed promising performance with 15°C reducing production temperature. Zeolite incorporation in WMA presents opportunities for sustainable pavement construction and warrants further investigation.
