【摘要】：通過(guò)實(shí)驗(yàn)確定基質(zhì)瀝青、SBS、橡膠粉、增塑劑、礦粉等組分的含量,得到一種高性能瀝青混凝土路面裂縫密封膠,并將其性能與現(xiàn)有瀝青混凝土路面修補(bǔ)材料如基質(zhì)瀝青、SBS改性瀝青、市售密封膠等進(jìn)行對(duì)比,分別從抗高溫、抗低溫、抗異物嵌入、抗腐蝕、抗拉伸性能等5個(gè)方面,結(jié)合溫度、老化條件進(jìn)行性能對(duì)比。結(jié)果表明:自制密封膠的軟化點(diǎn)高達(dá)94.2℃,彈性恢復(fù)率達(dá)到98%,遠(yuǎn)優(yōu)于其他3種材料,即具有較好的抗高溫和抗低溫性能;抗異物嵌入性能與其他3種材料基本相當(dāng);自制密封膠和市售密封膠(路斗士)經(jīng)柴油腐蝕后質(zhì)量損失率最小,僅為15%,即具有較佳的抗腐蝕性;基質(zhì)瀝青和SBS改性瀝青浸水前后的拉拔強(qiáng)度都較低,抗拉伸性能較差,自制密封材料老化前在不同溫度下都具有較高的拉拔強(qiáng)度,其中在0℃下高達(dá)1 MPa,但是老化后與市售密封膠性能基本相當(dāng)。
[Abstract]:A kind of high performance asphalt concrete pavement crack sealant was obtained by determining the content of matrix asphalt SBS, rubber powder, plasticizer, mineral powder and so on. And compared with the existing asphalt concrete pavement repair materials such as asphalt base asphalt modified asphalt SBS modified asphalt, marketable sealant and so on, respectively from five aspects of high temperature resistance, low temperature resistance, anti-foreign body embedding, corrosion resistance, tensile performance, etc. The results show that the softening point of self-made sealant is as high as 94.2 鈩，
