In this work, recycled polypropylene was exposed to gamma irradiation to form free radical on the polymer surface. Five different samples of modified bitumen were prepared with the modifier content, wt. 1, 3, 5, 7 and 9% and binders were investigated in term of chemical and physical properties by means of FT-IR spectroscopy, florescent microscope, conventional tests, short and long term aging procedures, rotational viscosity, dynamic shear and bending beam rheometer tests.trinfo:eu-repo/semantics/closedAccessBitumenrecycled polypropylenegamma irradiationmodificationArticle27374977513WOS:000386709600002Q4
