【摘要】：傳統(tǒng)的半剛性基層瀝青混凝土路面施工方法存在一定的弊端,主要問(wèn)題之一就是施工車輛容易造成半剛性基層的早期破壞�；诒M量減少瀝青路面的早期破壞的思路,本文著重研究了半剛性基層異步連續(xù)攤鋪技術(shù)。路面底基層與基層,基層與面層的連續(xù)施工是這種技術(shù)的一大特點(diǎn),也就是上層的施工是在下層的有效碾壓時(shí)間內(nèi)完成,通過(guò)同時(shí)異步連續(xù)攤鋪和碾壓完成上下基層的施工過(guò)程。在研究過(guò)程中,以理論為指導(dǎo)。廣泛查閱了有關(guān)半剛性基層瀝青路面的學(xué)術(shù)文獻(xiàn),了解、掌握了一些最新研究理論,并對(duì)有關(guān)資料進(jìn)行分析和匯總。同時(shí),結(jié)合大量的室內(nèi)試驗(yàn)數(shù)據(jù),采用力學(xué)分析軟件,對(duì)不同瀝青路面結(jié)構(gòu)層不同條件下的指標(biāo)進(jìn)行分析,研究了異步連續(xù)攤鋪技術(shù)的可行性。在滄州黃驊市307國(guó)道大修養(yǎng)護(hù)工程中采用異步連續(xù)攤鋪技術(shù)鋪筑了試驗(yàn)路段,并在底基層底預(yù)埋了用于監(jiān)測(cè)路面基層層底拉應(yīng)力的傳感器,通過(guò)對(duì)實(shí)際檢測(cè)得到的數(shù)據(jù)和理論分析計(jì)算得到的數(shù)據(jù)的對(duì)比發(fā)現(xiàn),應(yīng)用軟件分析計(jì)得到的算的結(jié)果準(zhǔn)確性較高,研究成果能夠應(yīng)用于實(shí)際的施工。
[Abstract]:The traditional construction method of semi-rigid base asphalt concrete pavement has some drawbacks, one of the main problems is that the construction vehicle is easy to cause the early destruction of semi-rigid base. Based on the idea of minimizing the early damage of asphalt pavement, this paper focuses on the asynchronous and continuous paving technology of semi-rigid base. One of the major features of this technology is the continuous construction of the base and the base, the base and the surface of the pavement. That is, the construction of the upper layer is completed within the effective rolling time of the lower layer. The construction process of upper and lower base is completed by simultaneous asynchronous continuous spreading and rolling. In the process of research, guided by theory. The academic literature about semi-rigid base asphalt pavement is consulted extensively, some latest research theories are grasped, and relevant data are analyzed and summarized. At the same time, combined with a large number of indoor test data and mechanical analysis software, the indexes of different asphalt pavement structure layer under different conditions are analyzed, and the feasibility of asynchronous continuous paving technology is studied. In the maintenance project of National Highway 307 in Cangzhou Huanghua City, the test section was paved with asynchronous continuous spreading technology, and the sensor used to monitor the tensile stress of the base layer of the pavement was embedded in the bottom of the base course. Through the comparison of the data obtained from the actual test and the data obtained by theoretical analysis and calculation, it is found that the accuracy of the calculation obtained by using the software analysis meter is high, and the research results can be applied to the actual construction.
