【摘要】：截至2014年底,中國大陸高速公路的通車總里程達(dá)11.195萬公里。早期建設(shè)的瀝青結(jié)構(gòu)路面大多已經(jīng)進(jìn)入到了維修或改建階段,這必然會(huì)帶來大量的瀝青廢料。乳化瀝青冷再生技術(shù)能很好的解決這個(gè)問題,該技術(shù)可提高資源利用率,保護(hù)生態(tài)環(huán)境,具有重要的研究意義。本文依托貴州省交通運(yùn)輸廳科技項(xiàng)目“山區(qū)高速公路瀝青路面冷再生技術(shù)體系的研究”。本項(xiàng)目依托工程是G60(貴州境,貴新段)K1730+000-K1826+000段瀝青混凝土路面維修工程。依G60維修工程之利,對(duì)乳化瀝青冷再生混合料的力學(xué)性能進(jìn)行了研究。本文首先評(píng)價(jià)了RAP的級(jí)配組成和回收瀝青老化程度等原材料的性質(zhì)情況;針對(duì)乳化瀝青和RAP之間的反應(yīng)過程和混合料強(qiáng)度產(chǎn)生機(jī)理進(jìn)行了研究;然后回顧總結(jié)了國內(nèi)外的幾種乳化瀝青冷再生混合料設(shè)計(jì)方法,并在試件成型和最佳用水量的確定上采用了和規(guī)范中稍有不同的方法。在對(duì)再生混料力學(xué)性能的研究中,本文設(shè)計(jì)了五種不同RAP用量的混合料、三種不同水泥用量的混合料,研究了RAP用量、水泥用量、乳化瀝青用量三個(gè)因素對(duì)劈裂強(qiáng)度、抗壓強(qiáng)度、抗壓回彈模量三個(gè)力學(xué)性能參數(shù)的影響。本文用正交設(shè)計(jì)法設(shè)計(jì)了一個(gè)三因素三水平的正交試驗(yàn),利用SPSS中的方差分析法研究了RAP用量、乳化瀝青用量、水泥用量以及三者之間的交互作用對(duì)劈裂強(qiáng)度的綜合影響。研究表明三者之間的交互作用對(duì)劈裂強(qiáng)度的影響是不顯著的。研究表明,乳化瀝青冷再生混合料具有良好的結(jié)構(gòu)承載力,配合比設(shè)計(jì)良好的再生混合料完全能滿足路面基層或者下面層對(duì)力學(xué)性能的要求。
[Abstract]:By the end of 2014, the total mileage of the highway in China was 111 thousand and 950 kilometers. The asphalt structure of the early construction was mostly in the stage of maintenance or reconstruction. This will inevitably bring a lot of asphalt waste. The cold recycling technology of emulsified asphalt can solve this problem well. This technology can improve the utilization of resources and protect the students. This paper relies on the research on the cold recycling technology system of the asphalt pavement of the mountain expressway in Guizhou province. This project is based on the project is the K1730+000-K1826+000 section of the asphalt concrete pavement maintenance project in the G60 (Guizhou, Guixin section). In accordance with the benefit of the G60 maintenance project, the emulsified bitumen The mechanical properties of the cold recycled mixture are studied. First, the properties of the raw materials, such as the gradation composition of RAP and the aging degree of the recycled asphalt, are evaluated. The reaction process between the emulsified bitumen and the RAP and the mechanism of the strength of the mixture are studied. Then, the cold regeneration of several emulsified bitumen at home and abroad is reviewed. In the study of the mechanical properties of recycled mixture, five kinds of mixture with different RAP dosage and three kinds of cement mixture are designed in the study of the mechanical properties of recycled mixture. The amount of RAP, the amount of cement and the amount of emulsified bitumen are studied by three factors. The influence of element on splitting strength, compressive strength and compression modulus of resilience is three. In this paper, orthogonal design is used to design an orthogonal experiment with three factors and three levels. The synthetic shadow of splitting strength is studied by using the method of variance analysis in SPSS, the dosage of RAP, the amount of emulsified asphalt and the interaction between the cement and the interaction between the three. The study shows that the interaction between the three has no significant effect on the splitting strength. The study shows that the cold recycled mixture of the emulsified asphalt has a good structural bearing capacity, and the well designed recycled mixture can fully meet the requirements of the mechanical energy of the pavement base or the lower layer.
