【摘要】：傳統(tǒng)廢膠粉改性瀝青因粘度較大,施工和易性差故其應(yīng)用受到一定限制。同為濕法工藝的Terminal Blend(TB)是采用高溫高速剪切分散工藝,使膠粉在瀝青中脫硫和解聚,而顯著降低結(jié)合料粘度(177℃粘度低于1.5Pa·s)的一種廢膠粉改性瀝青新技術(shù)。由于國(guó)際上尚未形成統(tǒng)一規(guī)范,目前中國(guó)對(duì)這兩種粘度顯著不同的膠粉改性瀝青概念和工程應(yīng)用認(rèn)識(shí)尚不充分。通過(guò)文獻(xiàn)回顧,對(duì)廢膠粉改性瀝青及其應(yīng)用進(jìn)行了綜述,重點(diǎn)介紹了TB技術(shù)的研究進(jìn)展。
[Abstract]:The application of traditional asphalt modified by waste rubber powder is limited due to its high viscosity, poor construction and ease. Terminal Blend (TB), which is the same wet process, is a new technology which uses high temperature and high speed shear dispersing process to desulphurize and depolymerize the rubber powder in asphalt, while significantly reducing the viscosity of binder (177 鈩，
