【摘要】：我國(guó)在進(jìn)行瀝青路面高速公路的建設(shè)過程當(dāng)中,應(yīng)用于瀝青路面表層的粗集料以輝綠巖以及玄武巖為主,極少用到石灰?guī)r,這是由于普遍的觀點(diǎn)認(rèn)為石灰?guī)r應(yīng)用于瀝青路面表層時(shí),瀝青路面的抗滑性能不能滿足要求。與此同時(shí),一方面由于我國(guó)近些年來新建的高速公路里程急速增長(zhǎng),玄武巖被大量消耗掉,而且玄武巖的開采比較困難、開采成本較高,這樣一來使得玄武巖的采購(gòu)價(jià)格也急劇上升,從而使得修建高速公路的成本相應(yīng)的提高。另外一方面,在我國(guó)境內(nèi),石灰?guī)r廣泛的儲(chǔ)藏在各個(gè)地區(qū),如果能夠?qū)⑹規(guī)r應(yīng)用于高速公路瀝青路面表層,那么將大大的節(jié)約修建高速公路的成本。基于這種情況,本文將結(jié)合實(shí)體工程,通過鋪筑200m的試驗(yàn)路段以及室內(nèi)瀝青混合料試件磨耗試驗(yàn)對(duì)石灰?guī)r瀝青混合料的抗滑性能性能進(jìn)行研究。同時(shí)對(duì)不同類型的石灰?guī)r的相關(guān)技術(shù)性能指標(biāo)進(jìn)行檢測(cè),對(duì)石灰?guī)r各個(gè)性能指標(biāo)進(jìn)行研究和分析。本文的主要研究?jī)?nèi)容如下:本文的主要研究方案是一方面按照規(guī)范推薦的方法對(duì)石灰?guī)r粗集料的抗滑耐磨各項(xiàng)性能指標(biāo)進(jìn)行了試驗(yàn)驗(yàn)證,分析石灰?guī)r粗集料的各項(xiàng)指標(biāo)性能是否在規(guī)范要求范圍以內(nèi)。另一方面進(jìn)行室內(nèi)加速磨耗試驗(yàn),對(duì)瀝青混合料的抗滑性能的影響因素進(jìn)行了研究和分析。本文還采用了實(shí)體工程法對(duì)石灰?guī)r用于瀝青路面的可行性進(jìn)行了相關(guān)研究,主要方法是通過鋪筑試驗(yàn)路段,并對(duì)試驗(yàn)路段的路用性能指標(biāo)進(jìn)行檢測(cè)。本文首先主要是對(duì)瀝青混合料抗滑性能進(jìn)行了相關(guān)研究,首先確定了進(jìn)行相關(guān)室內(nèi)試驗(yàn)研究,分別研究了集料類型以及級(jí)配對(duì)瀝青混合料抗滑速率的影響。分別以集料類型以及級(jí)配為變量進(jìn)行了瀝青混合料試件的室內(nèi)磨耗試驗(yàn),從而研究了集料類型、磨耗圈數(shù)以及級(jí)配對(duì)瀝青路面抗滑作用的影響。然后主要是通過對(duì)不同類型的石灰?guī)r的各項(xiàng)性能指標(biāo)進(jìn)行了檢測(cè),研究石灰?guī)r粗集料應(yīng)用于高速公路瀝青路面表層中時(shí),瀝青路面的抗滑耐磨性能是否能夠滿足相應(yīng)要求,在云南省大理至臨滄高速公路實(shí)體項(xiàng)目工地實(shí)驗(yàn)室對(duì)應(yīng)用于該項(xiàng)目中的石灰?guī)r粗集料進(jìn)行了相關(guān)檢測(cè)工作,具體是以《公路工程集料試驗(yàn)規(guī)程》中推薦的具體試驗(yàn)方法對(duì)石灰?guī)r粗集料進(jìn)行了各項(xiàng)技術(shù)性能檢測(cè)試驗(yàn),以驗(yàn)證石灰?guī)r粗集料應(yīng)用于高速公路瀝青路面表層時(shí)能否滿足相應(yīng)的路用性能要求。為得到石灰?guī)r用于瀝青路面表層在施工過程中需要嚴(yán)格控制的性能指標(biāo)提供了參考。最后,本文主要是提供對(duì)所鋪筑的試驗(yàn)路段的各項(xiàng)抗滑性能指標(biāo)進(jìn)行了檢測(cè)和分析,研究石灰?guī)r應(yīng)用于瀝青路面表層中實(shí)際的抗滑效果,為石灰?guī)r應(yīng)用于瀝青路面表層提供了實(shí)踐依據(jù)。本文的主要?jiǎng)?chuàng)新點(diǎn)在于將相關(guān)理論研究在實(shí)體工程中進(jìn)行了驗(yàn)證,為粗集料石灰?guī)r應(yīng)用于實(shí)際工程項(xiàng)目中提供了可靠的依據(jù)。
[Abstract]:In the course of the construction of asphalt pavement expressway in China, the coarse aggregates used in the surface layer of asphalt pavement are mainly diabase and basalt, and limestone is rarely used. This is due to the general view that when limestone is applied to the surface of asphalt pavement, the anti-skid performance of asphalt pavement can not meet the requirements. At the same time, on the one hand, due to the rapid increase in mileage of newly built highways in China in recent years, basalt has been consumed in large quantities, and the mining of basalt is more difficult and costly. As a result, the purchase price of basalt has risen sharply, and the cost of building highways has increased accordingly. On the other hand, in our country, limestone is widely stored in various areas. If limestone can be applied to the surface of asphalt pavement, it will greatly reduce the cost of highway construction. Based on this situation, this paper will study the skid resistance of limestone asphalt mixture through the test section of 200 m and the wear test of indoor asphalt mixture. At the same time, the related technical performance indexes of different types of limestone are tested, and each performance index of limestone is studied and analyzed. The main research contents of this paper are as follows: on the one hand, according to the method recommended by the standard, the performance of the coarse limestone aggregate is tested and verified. This paper analyzes whether the performance of limestone coarse aggregate is within the required range of specifications. On the other hand, indoor accelerated wear test is carried out to study and analyze the influencing factors of asphalt mixture's skid resistance. In this paper, the feasibility of using limestone in asphalt pavement is studied by using solid engineering method. The main method is to construct the test section and test the road performance index of the test road. In this paper, first of all, the anti-skid performance of asphalt mixture is studied. Firstly, the related laboratory test is carried out, and the effects of aggregate type and gradation on the anti-slip rate of asphalt mixture are studied respectively. Taking aggregate type and gradation as variables, the indoor wear tests of asphalt mixture specimens were carried out, and the effects of aggregate type, wear cycle number and gradation on the anti-skid effect of asphalt pavement were studied. Secondly, through the examination of various performance indexes of different types of limestone, the paper studies whether the skid resistance and wear resistance of asphalt pavement can meet the corresponding requirements when the coarse limestone aggregate is applied to the surface layer of highway asphalt pavement. In the site laboratory of the entity project of Dali to Lincang Expressway in Yunnan Province, the limestone coarse aggregate used in the project was tested. The concrete test method recommended in "Highway Engineering aggregate Test Code" is used to test the technical performance of coarse limestone aggregate. In order to verify whether the limestone coarse aggregate can meet the corresponding road performance requirements when it is applied to the surface layer of highway asphalt pavement. It provides a reference for the performance index of limestone used in the construction process of asphalt pavement surface. Finally, this paper mainly provides the testing and analysis of the anti-skid performance indexes of the experimental road sections, and studies the actual anti-skid effect of limestone applied to the surface of asphalt pavement. It provides a practical basis for the application of limestone to the surface of asphalt pavement. The main innovation of this paper lies in the verification of relevant theoretical research in physical engineering, which provides a reliable basis for the application of coarse aggregate limestone in practical engineering projects.
