【摘要】：坑槽是我國瀝青路面的主要病害之一,對(duì)路面坑槽進(jìn)行修補(bǔ)的方法主要有兩種:熱補(bǔ)法和冷補(bǔ)法。冷補(bǔ)法相對(duì)于熱補(bǔ)法而言,具有綠色環(huán)保,施工快速,修補(bǔ)質(zhì)量高,便利交通,可以儲(chǔ)存,可以在低溫和雨天的環(huán)境下對(duì)路面坑槽進(jìn)行修補(bǔ)的優(yōu)點(diǎn),能對(duì)路面產(chǎn)生的坑槽進(jìn)行及時(shí)的,高質(zhì)量的修補(bǔ)被廣泛的使用。路面再生技術(shù)作為一種瀝青路面修復(fù)技術(shù),能充分利用原路面銑刨下來的廢舊瀝青混合料,對(duì)舊料中的瀝青進(jìn)行了一定程度的再生,經(jīng)過再生的廢舊瀝青混合料用于路面的修復(fù)之后,路面的抗車轍能力有顯著的提高,減少了原材料的用量,節(jié)約了經(jīng)濟(jì)。本文對(duì)如何將廢舊瀝青混合料應(yīng)用到冷補(bǔ)法中這一課題展開了研究,即再生冷補(bǔ)瀝青混合料的研究與應(yīng)用。在對(duì)比了一般的冷補(bǔ)瀝青混合料實(shí)驗(yàn)室制備流程和一般的熱再生瀝青混合料實(shí)驗(yàn)室制備流程之后,設(shè)計(jì)出了再生冷補(bǔ)瀝青混合料的實(shí)驗(yàn)室拌和流程,該流程將熱再生技術(shù)和冷補(bǔ)技術(shù)很好的結(jié)合在一起,對(duì)舊料中的瀝青進(jìn)行了再生,節(jié)約了原材料,達(dá)到了使用要求。同時(shí)對(duì)冷補(bǔ)液的配置流程;基質(zhì)瀝青、隔離劑、冷補(bǔ)添加劑的添加比例進(jìn)行了研究,并對(duì)配置出來的冷補(bǔ)液做了黏度的檢測,結(jié)果證明配置出的冷補(bǔ)液符合使用要求。在再生冷補(bǔ)瀝青混合料的配合比設(shè)計(jì)方面提出了新的方法:確定最佳瀝青用量時(shí)采用的是經(jīng)驗(yàn)公式加上紙跡試驗(yàn)的方法,而沒有使用傳統(tǒng)的馬歇爾試驗(yàn)方法;在綜合了國內(nèi)外的冷補(bǔ)料評(píng)價(jià)方法之后建立了再生冷補(bǔ)瀝青混合料的評(píng)價(jià)體系,包括冷補(bǔ)料的黏聚性,黏附性,初始穩(wěn)定度,成型穩(wěn)定度,理想穩(wěn)定度,水穩(wěn)定性(浸水馬歇爾試驗(yàn)和凍融劈裂試驗(yàn)),儲(chǔ)存性以及和易性的評(píng)價(jià),確定了各個(gè)性能的試驗(yàn)方法和評(píng)價(jià)指標(biāo),以一般冷補(bǔ)料拌和流程制備出的冷補(bǔ)料作為對(duì)照組,取了兩種類型的冷補(bǔ)瀝青混合料進(jìn)行了各項(xiàng)試驗(yàn),試驗(yàn)結(jié)果證明兩種類型的冷補(bǔ)料各項(xiàng)性能滿足要求。對(duì)再生冷補(bǔ)瀝青混合料的生產(chǎn)、儲(chǔ)存和施工三方面進(jìn)行了說明,提出了生產(chǎn)、儲(chǔ)存和施工的應(yīng)用方法和注意事項(xiàng)。
[Abstract]:Potholes are one of the main diseases of asphalt pavement in our country. There are two main methods to repair pavement potholes: hot repair method and cold repair method. Compared with the thermal compensation method, the cold repair method has the advantages of green environmental protection, fast construction, high repair quality, convenient traffic, can be stored, and can repair the pavement potholes in low temperature and rainy days. The potholes produced by the road surface can be repaired in time and with high quality and are widely used. Pavement regeneration technology, as a kind of asphalt pavement repair technology, can make full use of the waste asphalt mixture milled and planed from the original pavement, and regenerate the asphalt in the old material to a certain extent. After the recycled waste asphalt mixture is used in pavement repair, the rut resistance of pavement is significantly improved, the amount of raw materials is reduced, and the economy is saved. In this paper, how to apply waste asphalt mixture to cold filling method is studied, that is, the research and application of recycled cold fill asphalt mixture. After comparing the general laboratory preparation process of cold fill asphalt mixture with the general laboratory preparation process of hot recycled asphalt mixture, the laboratory mixing process of recycled cold fill asphalt mixture is designed. The process combines thermal regeneration technology with cold compensation technology, regenerates the asphalt in the old material, saves raw materials and meets the requirements of use. At the same time, the configuration flow of cold rehydration fluid, the proportion of matrix asphalt, isolator and cold supplement additive were studied, and the viscosity of the cold rehydration liquid was tested. The results show that the cold rehydration liquid meets the requirements of application. In the aspect of mix proportion design of recycled cold fill asphalt mixture, a new method is put forward: the empirical formula plus paper test method is used to determine the optimum asphalt content, but the traditional Marshall test method is not used; After synthesizing the evaluation methods of cold filling at home and abroad, the evaluation system of recycled cold fill asphalt mixture is established, including the cohesion, adhesion, initial stability, molding stability and ideal stability of cold fill asphalt mixture. The water stability (immersion Marshal test and freeze-thaw split test), storage and ease of evaluation were evaluated, and the test methods and evaluation indexes of each performance were determined, and the cold supplement prepared by the general cold feed mixing process was used as the control group. Two types of cold fill asphalt mixture are tested, and the test results show that the properties of the two types of cold fill asphalt mixture meet the requirements. The production, storage and construction of recycled cold fill asphalt mixture are explained, and the application methods and matters needing attention in production, storage and construction are put forward.
