【摘要】：對彩色路面的廣泛應用標志著城市正快速步入現代化,它能有效改善道路空間環(huán)境,使路面與周圍建筑更加協調。目前,彩色瀝青路面普遍存在著造價高、推廣難等問題。我國大批己經完工通車使用的道路進入到修整養(yǎng)護階段,鉆研推行經濟、效果明顯、便于掌握的預防性養(yǎng)護方法是一種趨勢。乳化瀝青和以乳化瀝青為基礎的微表處工藝是重要的預防性養(yǎng)護方法,是對路面進行快速修整的有效措施。不過,伴隨著人們生活水平的不斷提高,對豐富多彩的生活環(huán)境充滿渴望。更重要的是,能源的嚴重匱乏以及傳統的瀝青路面施工技術的弊端給環(huán)境帶來了沉重的負擔,所以對彩色乳化瀝青的研究成為必然趨勢。本文的主要研究內容如下:首先初步確定制備彩色瀝青的原材料(芳烴油、萜烯樹脂、SBS、增塑劑DBP,氧化鐵紅),其中SBS選擇兩種備用,分別命名為1#SBS和2#SBS。其次,在確定彩色瀝青各原料的配比基礎上,通過對常規(guī)彩色瀝青制備工藝進行分析,確定本課題制備彩色瀝青的工藝,制備出1#SBS彩色瀝青和2#SBS彩色瀝青。對兩種彩色瀝青的性質進行檢測。選取1#SBS彩色瀝青進行后續(xù)研究。再次,通過對彩色乳化瀝青的制備工藝和參數進行分析,初步確定彩色乳化瀝青的制備工藝、乳化劑水溶液的PH值、乳化溫度等參數。乳化劑、改性劑和穩(wěn)定劑的用量通過如下步驟確定:①初步給出彩色乳化瀝青的預選配比:油水比62:38、乳化劑1.8%、改性劑3.5%、穩(wěn)定劑0.15%,改變乳化劑的用量,使其在0.6%~1.8%范圍內變化,得出乳化劑量改變時,瀝青材料性能的變化規(guī)律。最終確定瀝青乳液乳化劑用量為1.4%。②在油水比62:38、乳化劑1.4%、穩(wěn)定劑0.15%,通過改變改性劑SBS膠乳的用量使其分別為1%、2%、3%、4%、5%、6%,觀察蒸發(fā)殘留物的針入度、軟化點、5℃延度變化情況。趨勢圖表明,SBS膠乳改性劑的加入能夠使針入度降低,軟化點和5℃延度升高。當SBS膠乳含量從1%增加到5%時,針入度和軟化點兩大指標變化明顯,膠乳含量在5%~6%時,針入度和軟化點變化較緩慢。而隨著膠乳的量增加,延度是始終呈現出較快的增長趨勢,SBS膠乳可以有效改善瀝青材料的低溫性能。將SBS膠乳的用量最終確定在5%。③在油水比62:38、乳化劑1.4%、改性劑5%配方下,穩(wěn)定劑的量分別取0.05%、0.1%、0.15%、0.2%、0.25%,當穩(wěn)定劑的用量為0.2%時,瀝青乳液5d儲存穩(wěn)定性值最小。④綜上,在油水比62:38、乳化劑1.4%、改性劑5%,穩(wěn)定劑0.2%的配方下制備彩色乳化瀝青,并對其性能指標進行檢測。該彩色乳化瀝青材料性能指標能夠滿足JTGF40-2004的要求,但是蒸發(fā)殘留物的軟化點為55℃,低于57℃,不可作為微表處的原料用于南方較炎熱地區(qū)、重載交通路面和填補車轍,結合重慶地區(qū)常年溫度較高的實際情況,應采取相應措施對該彩色乳化瀝青的性能進行改進,再應用到工程中。另外,通過對制作混合料試件的加料拌和順序、擊實成型方法及養(yǎng)生條件進行試驗研究,提出了一種彩色乳化瀝青混合料的試驗方法,從而確定混合料配合比設計方法。通過車轍試驗、低溫彎曲試驗、黏附性試驗、凍融劈裂試驗,對不同環(huán)氧樹脂摻量下彩色乳化瀝青混合料的高溫穩(wěn)定性、低溫穩(wěn)定性和水穩(wěn)定性進行研究,得出混合料性能的變化規(guī)律。
[Abstract]:The extensive application of the color pavement marks the city's rapid modernization. It can effectively improve the road space environment and make the pavement more coordinated with the surrounding buildings. At present, the color asphalt pavement has a high cost and difficult promotion. The economical, effective and easy to master preventive maintenance is a trend. The emulsified bitumen and the micro surface technology based on the emulsified asphalt are the important preventive maintenance methods. It is an effective measure for the rapid repair of the pavement. However, with the continuous improvement of people's living standards, the rich and colorful living environment is full of thirst. More importantly, the serious shortage of energy and the disadvantages of traditional asphalt pavement construction technology have brought a heavy burden to the environment, so the study of color emulsified asphalt becomes an inevitable trend. The main contents of this paper are as follows: first of all, the raw materials (aromatic oil, terpene resin, SBS, plasticizer DB) are preliminarily determined. P, iron oxide red), in which SBS selected two kinds of reserve, named 1#SBS and 2#SBS., respectively. On the basis of determining the ratio of each raw material of color bitumen, by analyzing the preparation process of conventional color bitumen, the technology of preparing color bitumen in this subject was determined, and 1#SBS color asphalt and 2#SBS color bitumen were prepared. The properties of two kinds of color bitumen were made. The quality is tested. 1#SBS color asphalt is selected for follow-up research. Thirdly, through the analysis of the preparation technology and parameters of the color emulsified asphalt, the preparation process of the color emulsified asphalt, the pH value of the emulsifier water solution, the emulsification temperature and other parameters are preliminarily determined. The dosage of emulsifier, modifier and stabilizer is determined by the following steps: 1. The pre selected ratio of color emulsified asphalt: oil and water ratio 62:38, emulsifier 1.8%, modifier 3.5%, stabilizer 0.15%, change the dosage of emulsifier, change the emulsifier in the range of 0.6%~1.8%, and get the change law of asphalt material properties when the emulsifying dose changes. Finally, the dosage of emulsifier of asphalt emulsion is 1.4%., 62:38, emulsifier 1.4, and emulsifier 1.4. %, stabilizer 0.15%, by changing the dosage of modifier SBS latex to make it 1%, 2%, 3%, 4%, 5%, 6%, observe the needle penetration, softening point and 5 deduction of the evaporating residue. The trend diagram shows that the addition of SBS latex modifier can reduce the penetration of the needle and increase the ductility and the ductility of the softening point and 5 temperature. When the content of SBS latex is increased from 1% to 5%, the needle entry The change of two major indexes of degree and softening point is obvious. When the latex content is 5%~6%, the change of needle penetration and softening point is slow. With the increase of the amount of latex, the ductility is always showing a fast growth trend, and the SBS latex can effectively improve the low temperature performance of the asphalt material. The dosage of SBS latex is finally determined in the 62:38, emulsifier of oil and water in 5%. 1.4%, under the formula of modifier 5%, the amount of stabilizer is 0.05%, 0.1%, 0.15%, 0.2%, 0.25%. When the dosage of stabilizer is 0.2%, the storage stability value of the asphalt emulsion 5D is the smallest. 4. In a comprehensive way, color emulsified asphalt is prepared under the formula of oil and water ratio 62:38, emulsifier 1.4%, modifier 5% and stabilizer 0.2%, and the color emulsion is tested. The performance index of the asphalt material can meet the requirements of JTGF40-2004, but the softening point of the evaporated residue is 55 degrees C, lower than 57 degrees C, and it can not be used as the raw material for the micro surface to be used in the hot areas in the south. It should be reloaded on the Road and fill the rut. The corresponding measures should be taken to make the color emulsification combined with the actual conditions of high perennial temperature in Chongqing. The performance of the asphalt was improved and applied to the engineering. In addition, a test method of color emulsified asphalt mixture was put forward by testing the mixing order of the adding material of the mixture, the method of compaction and the condition of health, and the design method of the mixture ratio was determined. The test of the mixture and the low temperature bending test by the rutting test. The adhesive test and freezing thawing splitting test were carried out to study the high temperature stability, low temperature stability and water stability of the color emulsified asphalt mixture with different epoxy resin content, and the change law of the performance of the mixture was obtained.
