【摘要】：隨著社會(huì)的發(fā)展,運(yùn)輸行業(yè)在發(fā)揮著重要作用的同時(shí),也取得了高度的發(fā)展。道路建設(shè)在我國發(fā)展迅猛,隨著人均汽車擁有量逐年增加和車輛里程數(shù)的快速增加,許多公路尤其是國道和高速公路,已進(jìn)入全面的維修期。在道路建設(shè)以及養(yǎng)護(hù)方面,乳化瀝青也被廣泛的用在微表處、稀漿封層、碎石封層以及路面就地冷再生等方面。與普通瀝青混合料類似,乳化瀝青混合料強(qiáng)度構(gòu)成因素也是材料的內(nèi)聚力和內(nèi)摩阻力。乳化瀝青在實(shí)際工程中的路用性能還是取決于乳化瀝青破乳、固化之后的殘留物性能,乳化瀝青殘留物與填料形成的膠漿在路面中真正起到結(jié)合料的作用,因而確定出合適的乳化瀝青殘留物獲取方式,對(duì)于更好的模擬乳化瀝青在實(shí)際路面服役過程中的使用性能是非常關(guān)鍵的。目前很多高速公路瀝青路面產(chǎn)生早期破壞的原因,除了設(shè)計(jì)、施工方面的原因外,材料性能差也是很重要的原因。填料的使用就是其中一個(gè)不容忽視的問題。瀝青膠漿作為混合料最初的一級(jí)分散系統(tǒng),其結(jié)構(gòu)、組成與性能直接關(guān)系到瀝青混凝土的各項(xiàng)路用性能。本文首先對(duì)六種不同類型的礦粉進(jìn)行常規(guī)理化指標(biāo)檢測,并基于基質(zhì)瀝青膠漿性能對(duì)其作出評(píng)價(jià),以期篩選出能夠鑒別礦粉性能優(yōu)劣的重點(diǎn)指標(biāo)。六種礦粉的各項(xiàng)理化指標(biāo)實(shí)測結(jié)果均符合規(guī)范的要求,由于國內(nèi)外正在討論礦粉中小于0.02mm篩孔的材料數(shù)量的重要性,因此本文也重點(diǎn)對(duì)各類型的礦粉通過Winner 2008型激光粒度分析儀進(jìn)行細(xì)致的粒度組成分析。結(jié)合工程實(shí)際中所用的粉膠比制備基質(zhì)瀝青膠漿,通過灰色關(guān)聯(lián)分析方法,對(duì)六種礦粉的各項(xiàng)理化指標(biāo)與膠漿高低溫性能指標(biāo)進(jìn)行關(guān)聯(lián)分析,得出礦粉的親水系數(shù)、密度、細(xì)度模數(shù)、P20以及D10與基質(zhì)瀝青膠漿的關(guān)聯(lián)度較大。因此建議評(píng)價(jià)礦粉性能時(shí),應(yīng)將以上指標(biāo)作為重點(diǎn)指標(biāo)進(jìn)行分析評(píng)價(jià)。其次,對(duì)五種礦粉分別在五種粉膠比(0.6、0.8、1.0、1.2和1.4)下,制備乳化瀝青殘留物膠漿以及基質(zhì)瀝青膠漿,通過動(dòng)態(tài)剪切流變?cè)囼?yàn)、彎曲梁流變?cè)囼?yàn)以及壓力老化試驗(yàn)對(duì)其進(jìn)行高、低溫以及疲勞性能研究。結(jié)合實(shí)驗(yàn)室所具備的條件,依照品質(zhì)好的乳化瀝青要求對(duì)基質(zhì)瀝青性質(zhì)改變盡量小的理念,通過數(shù)據(jù)擬合分析確定出適宜的實(shí)驗(yàn)室乳化瀝青殘留物獲取方式為人工攪拌法。試驗(yàn)發(fā)現(xiàn)礦粉類型以及不同摻量對(duì)兩種類型膠漿的高、低溫以及疲勞性能都有著較大的影響,并且由同種礦粉配制兩種類型膠漿之間表現(xiàn)出的性能也有著明顯的差別。因此,應(yīng)根據(jù)施工方法合理的選擇礦粉類型以及摻量。最后,通過乳化瀝青混合料的劈裂試驗(yàn)進(jìn)行初步的性能驗(yàn)證。利用旋轉(zhuǎn)壓實(shí)儀成型試件,通過測量不同液體含量下試件孔隙率、干密度以及劈裂抗拉強(qiáng)度的變化,綜合各項(xiàng)指標(biāo)性能最佳時(shí),將6.5%的液體含量(乳化瀝青和水)作為冷再生混合料的最佳液體含量。在干、濕劈裂強(qiáng)度滿足規(guī)范要求的前提下,結(jié)合施工經(jīng)驗(yàn)以及經(jīng)濟(jì)效益方面考量,可以根據(jù)干濕劈裂強(qiáng)度比確定最佳乳化瀝青用量為3.4%。分別選擇1#和3#礦粉(兩種礦粉理化指標(biāo)有明顯的差異)作為礦物填料,試驗(yàn)發(fā)現(xiàn)在同等條件下,乳化瀝青混合料試件的劈裂強(qiáng)度存在一定的差別。
[Abstract]:With the development of society, the transportation industry plays an important role at the same time, also achieved a high degree of development. The road construction is developing rapidly in China, with the rapid increase of per capita car ownership increased year by year and the vehicle mileage, many roads especially State Road and highway, has entered the period of maintenance in road construction. And the maintenance of emulsified asphalt has been widely used in micro surfacing, slurry seal, seal and gravel pavement cold regeneration. Similar to the common asphalt mixture strength of emulsified asphalt mixture composed of cohesive force and internal friction factor is also the material of emulsified asphalt in practical engineering. The road performance depends on on the demulsification of emulsified asphalt residue, performance after curing, cement emulsified asphalt residue and the filler in the form of the road really play the role of binder, thus determine the appropriate milk Asphalt residue, emulsified asphalt for the simulation of better service performance in the process of actual pavement is very important. At present, a lot of expressway asphalt pavement early damage reasons, in addition to the design, construction and materials, the poor performance is also very important. The use of filler is one that can not be ignored the problem of asphalt mixture. As a decentralized system, its initial structure, composition and performance is directly related to the road asphalt concrete performance. Firstly, six kinds of ore powder of different types of physicochemical indexes, evaluation and performance of the asphalt mortar based on the make, in order to find out can the key index to identify performance. The powder of six kinds of powder physicochemical index test results conform to the standard requirements, at home and abroad are discussing ore powder The importance of the amount of material less than 0.02mm mesh, so this paper also focuses on the various types of mineral powder by Winner 2008 laser particle analyzer detailed analysis. By combining the size composition of engineering practice than rubber powder preparation of asphalt mortar, by the method of gray correlation analysis of the six types of mineral processing performance indexes high and low temperature indexes and mortar for correlation analysis, the hydrophilic coefficient, mineral density, fineness modulus, P20 and D10 associated with matrix asphalt mortar is large. So the evaluation of mineral properties, should be above refers to the analysis and evaluation standard as the key index. Secondly, five kinds of powder respectively in five kinds of powder binder ratio (0.6,0.8,1.0,1.2 and 1.4), the preparation of emulsified asphalt mortar and asphalt mortar residue, by dynamic shear test, bending beam rheometer test and pressure aging test of the For the high, low temperature and fatigue performance study. With combination of laboratory conditions, in accordance with the requirements of good quality of emulsified asphalt and asphalt properties change as small as possible concept, through data fitting analysis to determine the appropriate laboratory of emulsified asphalt residue with access to artificial mixing method. Experiment results showed that filler type and different dosage of two types rubbercement high, low temperature and fatigue performance have great influence, and by the same powder preparation performance between two types of mucilage showed also have significant differences. Therefore, should be based on reasonable construction method selection of filler type and content. Finally, the emulsified asphalt mixture splitting test the preliminary performance verification. The specimen by using rotation compaction molding, by measuring the content of different liquid samples under dry density and porosity, the splitting tensile strength change, comprehensive The best performance index, the liquid content of 6.5% (emulsified asphalt and water) as the cold recycled mixture. The best liquid content in the dry and wet splitting strength meet the standard requirements of the premise, combined with the construction experience and economic considerations, according to the wet splitting strength ratio to determine the optimal asphalt content for 3.4%. we used 1# and 3# powder (two kinds of powder physicochemical indexes had significant difference) as the mineral filler, the test found that under the same conditions, the emulsified asphalt mixture specimen splitting strength has certain difference.
