【摘要】：公路迅猛發(fā)展，優(yōu)質(zhì)集料需求越來越大，中堿性集料貯量不斷減少。而以花崗巖為代表的酸性集料在全國分布廣泛，，存儲量大，且質(zhì)地堅(jiān)硬耐磨，如果能夠解決酸性集料與瀝青的粘附性問題，使之能夠在工程中大量應(yīng)用，不僅可以解決瀝青路面修建中優(yōu)質(zhì)集料緊缺的問題，又能滿足表面層耐磨抗滑性能要求，同時(shí)又可降低工程成本，帶動(dòng)當(dāng)?shù)叵嚓P(guān)產(chǎn)業(yè)發(fā)展。 為解決瀝青與酸性集料的粘附性問題，本文基于花崗巖集料，選擇五種高分子材料作為原材料，利用Minitab軟件進(jìn)行配方試驗(yàn)設(shè)計(jì)，采用水煮法與光電比色法試驗(yàn)確定抗剝落劑的最佳配方，制備新型抗剝落劑A。分析不同摻量抗剝落劑A對瀝青感溫性能、高低溫性能以及粘附性的影響，確定抗剝落劑A的最佳摻量；選擇市場廣泛應(yīng)用產(chǎn)品B進(jìn)行對比試驗(yàn)，對比最佳摻量下兩種抗剝落劑對瀝青老化前后性能以及瀝青混合料水穩(wěn)定性、高低溫性能的影響。 結(jié)果顯示，抗剝落劑A的加入使瀝青組分聚集態(tài)發(fā)生變化，導(dǎo)致瀝青組分含量與結(jié)構(gòu)發(fā)生變化。瀝青與集料之間的粘附性等級由2級提高到5級，有效提高了瀝青與集料之間的粘附性；瀝青混合料的殘留穩(wěn)定度由65.4%提高到87.9%，凍融劈裂TSR值由60.3%提高到78.5%，顯著改善了其水穩(wěn)定性；低溫破壞應(yīng)變με值由2338提高到3009，大大改善了其低溫性能。與抗剝落劑B對比，二者作用效果一致，且在對高溫性能的影響方面，A的效果更好。 經(jīng)濟(jì)效益分析結(jié)果顯示，抗剝落劑A成本價(jià)格低，相較于B能夠節(jié)省31.1%的工程費(fèi)用增加量。
[Abstract]:With the rapid development of highway, the demand for high quality aggregate is increasing, and the storage of intermediate alkaline aggregate is decreasing. The acid aggregate represented by granite is widely distributed in China, with large storage capacity, and the texture is hard and wear-resistant. If we can solve the problem of adhesion between acid aggregate and asphalt, which can be used in a large number of projects, it can not only solve the problem of shortage of high-quality aggregate in the construction of asphalt pavement. It can also meet the requirements of wear resistance and skid resistance of surface layer, reduce the engineering cost and promote the development of local related industries. In order to solve the problem of adhesion between bitumen and acid aggregate, five kinds of polymer materials were selected as raw materials based on granite aggregate, and the formula was designed by Minitab software. The optimum formulation of anti-stripping agent A was determined by water boiling method and photoelectric colorimetry. The effects of different amount of anti-stripping agent A on the temperature sensitivity, high and low temperature properties and adhesion of asphalt were analyzed. Determine the best dosage of anti-stripping agent A; A comparative test was carried out with product B, which was widely used in the market. The effects of two kinds of anti-stripping agents on the performance of asphalt before and after aging, as well as on the water stability and high and low temperature performance of asphalt mixture were compared. The results show that the aggregate state of asphalt component changes with the addition of anti-stripping agent A, and the content and structure of asphalt component change, and the adhesion grade between asphalt and aggregate increases from 2 to 5. The adhesion between asphalt and aggregate is improved effectively. The residual stability of asphalt mixture was increased from 65.4% to 87.9, and the TSR value of freeze-thaw split increased from 60.3% to 78.5, which improved the water stability of asphalt mixture. The low temperature failure strain 渭 蔚 value was increased from 2338 to 3009, which greatly improved its low temperature performance. A works better. The results of economic benefit analysis show that the cost of anti-stripping agent A is lower than that of B, which can save 31.1% of the increase of engineering cost.
