【摘要】：大慶市地處哈大齊工業(yè)走廊核心區(qū)域，是黑龍江第二大經(jīng)濟(jì)強(qiáng)市。在國(guó)家實(shí)施振興東北老工業(yè)基地政策的刺激下，近幾年來(lái)，，大慶市的交通基礎(chǔ)設(shè)施建設(shè)也取得了空前的發(fā)展。在伴隨著大慶市交通設(shè)施的完善過(guò)程中，也出現(xiàn)了超載超限車輛，使得大慶市現(xiàn)有國(guó)省道交通運(yùn)輸十分繁重。在大慶市所轄的各國(guó)省道中，無(wú)論是舊路還是改建的新路，瀝青混凝土路面出現(xiàn)的病害都較多，這些病害的出現(xiàn)嚴(yán)重影響了所屬路面的使用性能及壽命，同時(shí)也加大了大慶市管養(yǎng)部門的養(yǎng)護(hù)維修工作。目前國(guó)內(nèi)對(duì)于瀝青混凝土病害的維修處治還基本上是依托一定的實(shí)驗(yàn)或經(jīng)驗(yàn)的基礎(chǔ)上。有些路面的維修處治就偏于保守,這無(wú)疑就會(huì)造成管養(yǎng)資金的浪費(fèi)，同時(shí)有些路面的維修處治又過(guò)于考慮經(jīng)濟(jì)，維修處治的效果沒(méi)有達(dá)到要求，使得病害在路面的后續(xù)使用過(guò)程又很快出現(xiàn)，這也會(huì)造成管養(yǎng)資金的浪費(fèi)。因此如何在有限的管養(yǎng)資金的情況下，制定合理的維修方案已成為大慶市管養(yǎng)部門亟待解決的問(wèn)題。 針對(duì)瀝青混凝土路面存在的問(wèn)題，本論文通過(guò)對(duì)大慶市的國(guó)省道中瀝青混凝土路面常見(jiàn)的病害進(jìn)行調(diào)查分析。結(jié)合大慶市的特點(diǎn)分別從結(jié)構(gòu)設(shè)計(jì)、路面施工、交通構(gòu)成、軸載特點(diǎn)及瀝青混凝土組成原料及級(jí)配等方面對(duì)幾個(gè)常見(jiàn)的病害產(chǎn)生原因進(jìn)行分析，并相應(yīng)給出了處治對(duì)策。論文在基于理論分析的基礎(chǔ)上，對(duì)舊路面銑刨前后的路面彎沉和當(dāng)量的變化趨勢(shì)進(jìn)行了研究。并結(jié)合一實(shí)際工程，對(duì)本論文的研究成果進(jìn)行論證。論文的研究成果對(duì)于解決大慶市的管養(yǎng)部門在有限的養(yǎng)護(hù)資金條件下做到對(duì)各路段的合理養(yǎng)護(hù)具有非常重要的指導(dǎo)意義。
[Abstract]:Daqing is located in the core region of the Hada-Qi industrial corridor and is the second most economically powerful city in Heilongjiang. Under the stimulus of the national policy of revitalizing the old industrial base in Northeast China, in recent years, Daqing traffic infrastructure has also made unprecedented development. Along with Daqing traffic facilities, there are overloaded and overlimited vehicles. The traffic and transportation of the existing provincial roads in Daqing City are very heavy. In the provincial roads of various countries under the jurisdiction of Daqing City, there are more diseases on asphalt concrete pavements, whether it is old roads or new roads that have been rebuilt. The emergence of these diseases has seriously affected the performance and service life of the pavement. At the same time, the maintenance and repair work of the management and maintenance department in Daqing City has also been increased. At present, the maintenance and treatment of asphalt concrete diseases in China is basically based on certain experiments or experiences. This will undoubtedly lead to waste of custody and maintenance funds, and at the same time, some pavement maintenance and treatment are too economical, the effect of maintenance and treatment has not met the requirements, and the disease will soon appear in the course of subsequent use of the pavement. Therefore, how to make a reasonable maintenance plan in the case of limited funds has become an urgent problem to be solved by the management and maintenance department of Daqing City. In view of the existing problems of asphalt concrete pavement, this paper investigates and analyzes the common diseases of asphalt concrete pavement in Daqing City, combining with the characteristics of Daqing City, respectively from the structural design, pavement construction, traffic composition, The causes of several common diseases are analyzed in the aspects of axial load characteristics, raw materials and gradation of asphalt concrete, and the corresponding countermeasures are given. The change trend of pavement deflection and equivalent before and after milling and planing of old pavement is studied. The research results of this paper have a very important guiding significance to solve the problem of reasonable maintenance of each section in Daqing City under the condition of limited maintenance funds.
