【摘要】：針對(duì)目前瀝青路面坑槽修復(fù)過(guò)程中出現(xiàn)的早期強(qiáng)度低、施工工藝復(fù)雜、對(duì)環(huán)境敏感性大、易出現(xiàn)二次破壞等問(wèn)題，本文通過(guò)查閱大量的文獻(xiàn)資料，在前期研究的基礎(chǔ)上，研發(fā)出了一種能夠適應(yīng)于潮濕環(huán)境下的早強(qiáng)快硬、流動(dòng)性好、施工簡(jiǎn)便的瀝青路面坑槽快速修復(fù)材料。 文章通過(guò)對(duì)材料之間相適性進(jìn)行研究，優(yōu)選出了瀝青路面快速修復(fù)材料的原材料，，確定了水泥、乳化瀝青以及其它外加劑之間最佳配合比例，并研究了不同配比參數(shù)下此種修復(fù)材料的流動(dòng)性能和強(qiáng)度的影響規(guī)律，在此基礎(chǔ)之上提出了瀝青路面快速修復(fù)材料配合比設(shè)計(jì)方法。 本文根據(jù)對(duì)瀝青路面快速修復(fù)材料的初步研究及其配合比組成設(shè)計(jì)研究成果，對(duì)其材料的強(qiáng)度與模量、高溫穩(wěn)定性、低溫抗裂性、水穩(wěn)定性以及耐久性能和疲勞性能進(jìn)行深入的研究，以期從整體上把握瀝青路面坑槽快速修復(fù)材料的性能、特點(diǎn)，綜合分析修復(fù)材料的路用性能和耐久性能的主要影響因素。結(jié)果表明當(dāng)選取合適摻配比例配制的瀝青路面快速修復(fù)材料具有良好的路用性能、耐久性能及APA疲勞性能。 通過(guò)研究瀝青路面快速修復(fù)材料的強(qiáng)度形成機(jī)理發(fā)現(xiàn)，其強(qiáng)度形成主要取決于乳化瀝青與集料之間的相互作用，水泥與乳化瀝青的網(wǎng)狀互穿結(jié)構(gòu)以及水泥水化產(chǎn)物和瀝青形成的互穿結(jié)構(gòu)與集料的粘附性這三方面作用，而這些作用將直接影響到修復(fù)材料的力學(xué)性能、路用性能以及耐久性能。 通過(guò)對(duì)界面處理材料進(jìn)行研究發(fā)現(xiàn)，采用界面材料處理瀝青路面快速修復(fù)材料與瀝青混合料之間的界面粘結(jié)強(qiáng)度及剪切強(qiáng)度能夠得到明顯提高。隨后又將瀝青路面快速修復(fù)材料應(yīng)用于瀝青路面坑槽修復(fù)中，并且提出了現(xiàn)場(chǎng)施工工藝技術(shù)。
[Abstract]:In view of the problems such as low early strength, complex construction technology, high sensitivity to environment and easy to occur secondary damage in the process of repairing potholes in asphalt pavement, this paper, through consulting a large number of documents and materials, based on the previous research, A kind of quick repairing material of asphalt pavement potholes is developed, which can be used in wet environment, which has the advantages of early strength and fast hardening, good fluidity and easy construction. In this paper, through the study of the compatibility between the materials, the raw materials for the rapid restoration of asphalt pavement are selected, and the optimum proportion of cement, emulsified asphalt and other admixtures is determined. The influence of different ratio parameters on the fluidity and strength of this kind of material is studied. Based on this, the design method of mix ratio of asphalt pavement rapid repair material is put forward. In this paper, according to the preliminary research of the asphalt pavement rapid repair material and the research results of its mixture composition design, the strength and modulus, the high temperature stability, the low temperature crack resistance of the material are studied. The water stability, durability and fatigue performance are studied in order to grasp the performance and characteristics of the asphalt pavement pothole fast repairing material, and to analyze comprehensively the main influencing factors of the pavement performance and durability of the repair material. The results show that the asphalt pavement rapid repair material with suitable blending ratio has good road performance, durability and APA fatigue performance. By studying the mechanism of strength formation of asphalt pavement repairing materials, it is found that the strength formation mainly depends on the interaction between emulsified asphalt and aggregate. The network interpenetrating structure between cement and emulsified asphalt and the adhesion between cement hydration product and asphalt interpenetrating structure and aggregate will directly affect the mechanical properties of the repair material. Road performance and durability. It is found that the interfacial bond strength and shear strength between the rapid repair material and the asphalt mixture can be improved obviously by using the interface material. Then the asphalt pavement rapid repair material is applied to the asphalt pavement pit repair, and the field construction technology is put forward.
