Description
本出願は、2015年12月31日に出願された米国仮出願第62/273,742号の利益を主張するものであり、さらに、2016年12月6日に出願された米国特許出願第15/370,683号の利益を主張するものである。
本発明は、一般に発泡アスファルト組成物、該発泡アスファルト組成物を含む再生アスファルト組成物、該発泡アスファルト組成物を含むアスファルト舗装材、および該発泡アスファルト組成物を使用したアスファルト舗装材の形成方法に関する。より詳細には、本発明は、ひずみ耐性にすぐれたアスファルト舗装材を提供する発泡アスファルト組成物、および該発泡アスファルト組成物を用いたアスファルト舗装材の形成方法に関する。
発泡アスファルト組成物(FAC)は、アスファルト基剤成分を約160℃まで加熱することによって作製され(表AIの比較用発泡アスファルト組成物作製のため)、続いてOxHDPEを添加し、アスファルト混合物を形成する(表AIの発泡アスファルト組成物作製のため)。アスファルト基剤成分およびアスファルト混合物のそれぞれを、発泡アスファルト装置に加え、続いて、水および圧縮空気を用いて発泡し、FACを形成した。表AIは、FACの総重量に基づき、FACに含まれる成分全ての量を重量%で表したリストである。
この実施例では、実施例Aで記載したのと同じ方法でFACを作製したが、OxHDPEの代わりに、OxHDPEといくつかの追加の重合体の組み合わせも使用した。表BIでは、FACの総重量に基づき、FACに含まれる成分全ての量を重量%で表したリストが与えられている。
