DETERMINATION EXTENSIONAL VISCOSITY AND CRACKING INDEX OF SULFURE WASTE MODIFIED ASPHALT CEMENT
In the northern Iraqi provinces, cracking distress due to the variations in temperatures is occurred in most of paved roads with asphaltic materials. This type of distress results in alligator and longitudinal cracking, spallings due to temperatures variations.This research determined the index of cracking and extensional viscosity of sulfur waste/asphalt cement (SWMAC). Four dosages of sulfur waste were selected and mixed into 40-50 pent. grade asphalt binder. Physical tests including: penetration, ductility, softening degree, absolute viscosity, elastic moduli, temperature effects, ageing, index of cracking, extensional viscosity, and morphology assays were performed on SWMAC. SWMAC presents higher extensional viscosity, moduli of elasticity and durability traits with superior cracking resistance at low temperature.
