【摘要】：隨著我國道路網(wǎng)絡(luò)的不斷延伸,道路交通量急劇增加,公路路面的養(yǎng)護工作日趨嚴(yán)峻,路面養(yǎng)護急需不受氣候條件限制的高性能修補材料,而水性環(huán)氧乳化瀝青混合料作為一種優(yōu)良的修補材料,能在常溫下對路面進行快速修補。為此,本文開展環(huán)氧乳化瀝青及混合料的研究。 依據(jù)水性環(huán)氧乳化瀝青及其混合料的研究現(xiàn)狀和存在的問題,本文主要進行如下研究： ①選用賦予環(huán)氧樹脂柔韌性的脂肪族丙烯酸樹脂PF5233作為環(huán)氧樹脂增韌改性劑,多元胺類固化劑T450作為柔性樹脂體系固化劑,乳化劑PF108作為制備水性環(huán)氧樹脂乳液的乳化劑。根據(jù)本實驗的目的,考慮固化時間,綜合考慮選用E-51/PF5233=1:1的組分作為拌制混合料的膠結(jié)料中環(huán)氧體系的配方。采用相反轉(zhuǎn)法制備水性環(huán)氧樹脂乳液,選用PF108乳化劑,其用量為10%。采用電子顯微鏡觀察水性環(huán)氧樹脂乳液的微觀形貌,結(jié)果顯示環(huán)氧樹脂較均勻地分布在介質(zhì)水中。 ②通過對乳化瀝青的乳化機理和乳化條件的分析,選用陰離子型乳化劑U-58作為瀝青乳化劑,其用量為1.1%。采用電子顯微鏡觀察乳化瀝青的微觀形貌,結(jié)果顯示乳化效果較好。 ③通過對改性乳化瀝青的改性機理的分析及其制備方法的對比,水性環(huán)氧樹脂乳液、固化劑和乳化瀝青對環(huán)氧乳化瀝青性能的影響分析,對膠結(jié)料進行界面拉拔試驗和界面拉伸試驗,結(jié)果顯示：當(dāng)水性環(huán)氧乳液與乳化瀝青的比列為1：1時,固化時間滿足實驗要求,抗拉強度較強,斷裂伸長率符合規(guī)范要求。 ④在配制好水性環(huán)氧乳化瀝青的基礎(chǔ)上,對環(huán)氧乳化瀝青混合料配合比進行優(yōu)化設(shè)計,并對其路用性能進行了系統(tǒng)的研究。路用性能表明,環(huán)氧乳化瀝青混合料具有良好的高溫穩(wěn)定性、水穩(wěn)定性及低溫性能,且開放交通時間滿足施工要求。 ⑤探討了在工程應(yīng)用中乳化劑用量、用水量、填料及拌合條件等因素對施工性能的影響,并提出了相應(yīng)地注意事項。
[Abstract]:With the continuous extension of the road network in our country, the traffic volume of the road increases rapidly, and the maintenance work of the road surface becomes more and more serious. The maintenance of the road surface is in urgent need of high performance repair materials which are not restricted by the climatic conditions. As an excellent repair material, waterborne epoxy emulsified asphalt mixture can quickly repair the pavement at room temperature. Therefore, the study of epoxy emulsified asphalt and its mixture is carried out in this paper. According to the current research situation and existing problems of waterborne epoxy emulsified asphalt and its mixture, the main research in this paper is as follows:. (1) the fatty acrylic resin (PF5233), which gives flexibility to epoxy resin, was selected as toughening modifier for epoxy resin, and the polyamine curing agent T450 was used as curing agent for flexible resin system. The emulsifier PF108 is used as emulsifier to prepare waterborne epoxy emulsion. According to the purpose of this experiment, the curing time is considered. The composition of E-51 / PF5233C-1 / 1 is considered as the formulation of epoxy system in the binder of mixed mixture, the waterborne epoxy emulsion is prepared by reverse conversion method, and the PF108 emulsifier is used. The microcosmic morphology of waterborne epoxy resin emulsion was observed by electron microscope. The results showed that the epoxy resin distributed uniformly in the medium water. 2 through the analysis of emulsification mechanism and emulsification conditions of emulsified asphalt, anionic emulsifier U-58 was selected as asphalt emulsifier, and its dosage was 1.1. The microscopic morphology of emulsified asphalt was observed by electron microscope. The results showed that the emulsifying effect was better. (3) by analyzing the modification mechanism of modified emulsified asphalt and comparing its preparation methods, the effects of waterborne epoxy resin emulsion, curing agent and emulsified asphalt on the performance of epoxy emulsified asphalt were analyzed. The results show that when the ratio of waterborne epoxy emulsion to emulsified asphalt is 1: 1, the curing time meets the experimental requirements, the tensile strength is strong, and the elongation at break meets the standard requirement. On the basis of preparing waterborne epoxy emulsified asphalt, the mixture ratio of epoxy emulsified asphalt mixture is optimized and its road performance is studied systematically. Epoxy emulsified asphalt mixture has good high temperature stability, water stability and low temperature performance, and open traffic time to meet the construction requirements. 5. The influence of emulsifier dosage, water consumption, filler and mixing condition on the construction performance is discussed, and the corresponding points for attention are put forward.
