Rheological studies of asphalt modified with elastomeric polymer
https://orcid.org/0000-0001-8427-9042
Abstract Reactive polymers, consisting of glycidyl methacrylate, produce a chemical reaction between the polymer and the asphalt binder that can be beneficial for asphalt application in hot climates. Elastomeric-modified-bitumen mixes were developed using elastomeric polymer (EMA-GMA), high density polyethylene (HDPE) and polyphosphoric acid (PPA 116%). Physical and rheological properties of modified bitumen, complex modulus (|G ∗|), phase angle (), and MSCR test were analyzed. Test results of penetration, softening point and elastic recovery showed an increase of elastic behavior in modified asphalts and produced material properties suitable for application in highway construction. Based on rheological test results, it was observed that the addition of polymer can increase the range of temperature, in asphalt, to resist permanent deformation. MSCR test results characterize the modified asphalt as an elastomeric with good performance at intermediate temperatures.
