Abstract : based on the analysis of the main failures discovered in pavement on steel deck plate and the demanding service condition of the pavement on steel deck, high - temperature rutting test, low - temperature bending test and controlled stress flexural fatigue test are used to study the performance of asphalt mixtures modified by epoxy resin including high - temperature stability, low - temperature cracking - resistance, and fatigue cracking - resistance, which are served to evaluate the modification effect of epoxy resin of different contents. with the addition of epoxy resin, all the three performances are improved greatly. however, when the amount of epoxy resin added is over a certain value, the modification effect will be stable with no extra benefit detected. finally, in terms of the properties of the three respects, 20 ?, 30 ?, 30 ? are given separately as the proposal adding contents
文摘:在分析鋼橋面鋪裝層主要病害和特殊工作環境的前提下,分別採用高溫車轍試驗、低溫小梁彎曲試驗和控制應力小梁彎拉疲勞試驗,研究了不同環氧樹脂摻量下的環氧樹脂改性瀝青混合料的高溫穩定性、低溫抗裂性和抗疲勞性能.試驗結果表明:環氧樹脂對這3個方面都有很大的改進效果,但改性效果和樹脂的添加量並不是一個無限遞增的關系,當添加量超過一定數值以後,改性的效果將趨于平穩.最後就高溫、低溫、疲勞3個方面分別提出環氧樹脂添加量為20 ? , 30 ? , 30 ?的建議值Based on the analysis of the main failures discovered in pavement on steel deck plate and the demanding service condition of the pavement on steel deck, high - temperature rutting test, low - temperature bending test and controlled stress flexural fatigue test are used to study the performance of asphalt mixtures modified by epoxy resin including high - temperature stability, low - temperature cracking - resistance, and fatigue cracking - resistance, which are served to evaluate the modification effect of epoxy resin of different contents. with the addition of epoxy resin, all the three performances are improved greatly. however, when the amount of epoxy resin added is over a certain value, the modification effect will be stable with no extra benefit detected. finally, in terms of the properties of the three respects, 20 ?, 30 ?, 30 ? are given separately as the proposal adding contents
