【摘要】：隨著瀝青混合料回收利用需求的加大,在廠拌熱再生技術的基礎上,瀝青混合料溫拌再生技術被廣泛關注。溫拌再生瀝青混合料是一種新的“資源節(jié)約型”、“綠色環(huán)保型”瀝青混合料,它結(jié)合了瀝青溫拌技術和混合料熱再生技術兩者的優(yōu)點,能源消耗量和生產(chǎn)攤鋪過程中廢氣排放量相對于廠熱拌下降很多,而且具有較好的路用性能,應用前景十分廣闊。由于溫拌再生技術在國內(nèi)外的應用研究還處于初步階段,熱拌再生中舊瀝青混合料(RAP)的再生利用率一直難以提高,溫拌再生技術能降低混合料成型時的拌制溫度,進而提高RAP的摻量,本文針對RAP摻量的問題進行了相關研究。首先對試驗的原材料進行了基本性能的試驗,通過比較選擇了溫拌性能較好的Evotherm 3G溫拌劑,并進行了Evotherm 3G溫拌劑對新老瀝青性能的影響測試。對RAP進行性能試驗,通過抽提篩分,對舊瀝青進行性能分析,確定了舊瀝青的老化程度,其次選擇40%、50%和60%三個不同的RAP摻量進行了溫拌再生瀝青混合料的目標配合比設計,確定了三種不同RAP摻量下再生混合料的最佳油石比,最后進行了不同RAP摻量下溫拌再生瀝青混合料的路用性能試驗,通過試驗發(fā)現(xiàn),在AC-16C級配條件以及使用Evotherm 3G溫拌劑時,在不高于60%RAP摻量下再生混合料的高溫性能和低溫性能隨著RAP摻量的增加而增加,水穩(wěn)定性能隨著RAP摻量的增加而減小,但都能滿足規(guī)范規(guī)定的最低路用性能標準。通過本研究實現(xiàn)了滿足我國瀝青路面路用性能標準的高達60%RAP摻量下的溫拌再生瀝青混合料的制備,為進一步提高RAP再生利用率打下基礎,為溫拌再生技術規(guī)范的編制提供了依據(jù),在實際工程中,對現(xiàn)有的再生瀝青混合料設計有一定的指導性建議,使得高比例舊料再生技術能與實際工程相結(jié)合進行高等級路面的建設與維護成為可能。
[Abstract]:With the increasing demand for asphalt mixture recycling, the hot mix recycling technology of asphalt mixture has been paid more and more attention on the basis of hot mix recycling technology. Warm mix and recycled asphalt mixture is a new kind of "resource saving", "green environmental protection" asphalt mixture, which combines the advantages of warm mix asphalt technology and hot recycling technology of mixture. The energy consumption and the exhaust gas emissions in the process of production and spreading are much lower than that in the hot mixing plant, and have good road performance, and the application prospect is very broad. Since the application of warm mix recycling technology in domestic and foreign research is still in the initial stage, it is difficult to improve the recycling efficiency of hot mix and old asphalt mixture rap, and warm mix regeneration technology can reduce the mixing temperature of the mixture when it is formed. In order to improve the content of RAP, this paper studies the problem of RAP content. At first, the basic properties of the raw materials were tested, and the Evotherm 3G warm mix agent with better warm mixing performance was selected, and the effect of Evotherm 3G warm mix agent on the performance of new and old asphalt was tested. The performance test of RAP was carried out, and the performance of old asphalt was analyzed by extracting and sifting. The aging degree of old asphalt was determined. Then, three different RAP contents of 40% and 60% were selected to design the target mix ratio of warm mix recycled asphalt mixture. The optimum ratio of oil to stone was determined for three kinds of recycled asphalt mixture with different RAP content. Finally, the road performance test of warm mixed recycled asphalt mixture with different RAP content was carried out. It was found that under the condition of AC-16C gradation and the use of Evotherm 3G warm mix agent, the road performance test of recycled asphalt mixture under different RAP content was carried out. The high temperature and low temperature properties of recycled mixture increase with the increase of RAP content, while the water stability decreases with the increase of RAP content, but all of them can meet the minimum road performance standard stipulated in the code. Through this study, the preparation of warm mix recycled asphalt mixture with high 60%RAP content, which meets the performance standard of asphalt pavement in China, is realized, which lays a foundation for further improving the recycling efficiency of RAP. It provides the basis for the compilation of the technical specification for warm mixing and recycling. In the actual engineering, it has some guiding suggestions for the design of the existing recycled asphalt mixture. It is possible to combine the high proportion old material recycling technology with the actual engineering for the construction and maintenance of high grade pavement.
