【摘要】：我國的高速公路建設(shè)最近幾十年取得了飛速的發(fā)展,隨著高速公路通車?yán)锍痰脑黾?高速公路特別是瀝青路面高速公路的路面使用性能評價(jià)越來越重要。高速公路瀝青路面的使用功能隨著時(shí)間推移逐年下降,甚至?xí)霈F(xiàn)車轍、裂縫、沉陷、龜裂等破損病害,嚴(yán)重影響路面的舒適性,甚至影響到行車安全。所以說對高速公路路面使用性能評價(jià)的研究就顯得十分必要和有意義。本文首先介紹了國內(nèi)外對于路面使用性能評價(jià)系統(tǒng)的研究現(xiàn)狀,結(jié)合我國工程的實(shí)際情況對路面檢測的新技術(shù)做詳細(xì)的論述。其次,對我國高速公路路面評價(jià)的影響要素、評價(jià)指標(biāo)和評價(jià)標(biāo)準(zhǔn)做了深入的剖析和探討。瀝青路面規(guī)范對路用性能的評價(jià)指標(biāo)和標(biāo)準(zhǔn)做了規(guī)定,本文結(jié)合惠河高速的實(shí)際情況,對其路面路用性能的檢測和評價(jià)做了研究。最后,以TOPSIS法為依托進(jìn)行了惠河高速公路選取路段的綜合評價(jià),并與規(guī)范評定指標(biāo)評定結(jié)果做了對比。然后運(yùn)用Abaqus有限元軟件,分別評價(jià)在標(biāo)準(zhǔn)軸載和重荷載作用下廣東惠河高速的路面結(jié)構(gòu)力學(xué)性能,以此驗(yàn)證路面結(jié)構(gòu)設(shè)計(jì)的準(zhǔn)確性。本文將TOPSIS評價(jià)方法引入到對瀝青路面質(zhì)量評價(jià)當(dāng)中,且采用了主客觀相結(jié)合的賦權(quán)方法對指標(biāo)進(jìn)行賦權(quán),使瀝青路面的評價(jià)更加客觀準(zhǔn)確,從而為高速公路瀝青路面的評價(jià)提供借鑒和參考,其現(xiàn)實(shí)應(yīng)用的意義深遠(yuǎn)。
[Abstract]:The expressway construction in our country has made rapid development in recent decades. With the increase of expressway mileage, it is more and more important to evaluate the pavement performance of expressway, especially asphalt pavement expressway. With the passage of time, the use function of highway asphalt pavement will decline year by year, even will appear rutting, crack, subsidence, crack and other damaged diseases, seriously affect the comfort of the road, and even affect the driving safety. Therefore, it is very necessary and meaningful to study the evaluation of expressway pavement performance. This paper first introduces the research status of pavement performance evaluation system at home and abroad, and discusses in detail the new technology of pavement detection combined with the actual situation of China's engineering. Secondly, the influencing factors, evaluation indexes and evaluation criteria of expressway pavement evaluation in China are analyzed and discussed in depth. The evaluation index and standard of pavement performance are stipulated in the specification of asphalt pavement. Combined with the actual situation of Huihe high speed, the detection and evaluation of pavement performance are studied in this paper. Finally, the comprehensive evaluation of selected sections of Huihe Expressway based on TOPSIS method is carried out, and the results are compared with the standard evaluation index. Then the mechanical properties of the pavement structure of Huihe highway in Guangdong province under the action of standard axle load and heavy load are evaluated by using Abaqus finite element software to verify the accuracy of pavement structure design. In this paper, the TOPSIS evaluation method is introduced into the evaluation of asphalt pavement quality, and the subjective and objective weighting method is used to weight the index, which makes the evaluation of asphalt pavement more objective and accurate. Thus, it provides reference and reference for the evaluation of highway asphalt pavement, and its practical application is far-reaching.
