Get Moreresearchers found that limestone filler altered the hydration rate and reacted with cement to form calcium carbosilicate and carboaluminate hydrates 56 However the major effect of limestone filler is believed to be a physical dilution of the binder thereby reducing the strength The epoxy bitumen containing limestone filler was also tougher showing higher elongationtobreak than the mastics generated with hydrated lime Even though the epoxy bitumen containing limestone was the strongest and toughest material it exhibited higher susceptibility to fracture after 80 h in PAV than of the same binder with hydrated lime
