Evaluation of the Influence of Antistripping Agents on Water Sensitivity of the Stone Matrix Asphalt Mixture Modified by Recycled Ground Tire Rubber and Waste Polyethylene Terephthalate

This research intends to evaluate the effects of waste polyethylene terephthalate (PET), antistripping agents (ASA), and ground tire rubber (GTR) on performance properties stone matrix asphalt (SMA) mix binder/water damage resistance. Liquid agents, added 85/100 penetration grade binder ASA effects, were A (M500), B (EvothermM1), C (LOF-6500). Tests conducted study modified bitumen’s rheological included softening point, penetration, rotational viscosity (RV), dynamic shear rheometer (DSR), tests performed in order examine moisture sensitivity Texas boiling resilient modulus (MR), fracture energy (FE), indirect tensile strength (ITS) ratio tests. Results showed that MR, ITS, FE mixes with crumb (CR), ASA, PET improved. Adding 50% PET, CR, (B) led highest strength, modulus, ratios showing a perfect water susceptibility mentioned mix.
