【摘要】：山區(qū)國省干線公路作為發(fā)展地方經(jīng)濟(jì)重要的基礎(chǔ)設(shè)施,在公路路網(wǎng)中發(fā)揮著越來越重要的作用。與此同時,隨著公路使用年限的增加,山區(qū)公路瀝青路面的使用性能卻日漸下降,因此,它的養(yǎng)護(hù)問題也越來越受到公路建設(shè)者的普遍關(guān)注。針對貴州山區(qū)公路養(yǎng)護(hù)規(guī)模逐步擴(kuò)大而養(yǎng)護(hù)資金又有限的實(shí)際情況,為保持路面優(yōu)良的使用性能,減少路面早期病害的發(fā)生,延緩病害的不良發(fā)展,使道路使用壽命延長和降低養(yǎng)護(hù)成本,應(yīng)跟據(jù)山區(qū)公路瀝青路面的使用性能,適時選擇符合其特點(diǎn)的技術(shù)對其進(jìn)行預(yù)防性養(yǎng)護(hù)。鑒于目前的預(yù)養(yǎng)護(hù)方式有多種,如就地?zé)嵩偕?超)薄層罩面、微表處、稀漿封層、霧封層、碎石封層,如何選擇一種適應(yīng)貴州山區(qū)干線公路的快速養(yǎng)護(hù)方式成為一個問題。基于此,本文提出對山區(qū)國省干線公路進(jìn)行就地?zé)嵩偕捅诱置娴募夹g(shù)經(jīng)濟(jì)評價研究。 本文首先探討了貴州山區(qū)國省干線公路早期典型病害及發(fā)展機(jī)理,提出通過技術(shù)經(jīng)濟(jì)評價的方法在就地?zé)嵩偕捅诱置嬷羞x擇一種合適山區(qū)干線公路養(yǎng)護(hù)是養(yǎng)護(hù)方式,然后對山區(qū)干線公路養(yǎng)護(hù)方式的技術(shù)經(jīng)濟(jì)評價進(jìn)行了系統(tǒng)的理論分析,指出通過技術(shù)適應(yīng)性、經(jīng)濟(jì)適應(yīng)性和社會效益三個方面對山區(qū)干線公路的養(yǎng)護(hù)方式進(jìn)行技術(shù)經(jīng)濟(jì)評價。 本文的重點(diǎn)是技術(shù)適應(yīng)性評價和經(jīng)濟(jì)適應(yīng)性評價,特別是技術(shù)適應(yīng)性評價模型的構(gòu)建和評價體系的建立,本文用AHP—TOPSIS方法構(gòu)建技術(shù)適應(yīng)型評價模型,再應(yīng)用等效年度費(fèi)用法等方法分析養(yǎng)護(hù)方式的經(jīng)濟(jì)適應(yīng)性,社會效益進(jìn)行定性分析描述。最后依托2013年分別運(yùn)用就地?zé)嵩偕捅诱置婕夹g(shù)進(jìn)行養(yǎng)護(hù)的貴州兩條干線公路進(jìn)行技術(shù)經(jīng)濟(jì)分析實(shí)例論證。 技術(shù)經(jīng)濟(jì)評價結(jié)果表明：地?zé)嵩偕捅诱置孀鳛闉r青路面養(yǎng)護(hù)中的一種就地快速修復(fù)技術(shù),它們都改善原瀝青路面級配和路面路用性能,達(dá)到養(yǎng)護(hù)要求,從而延長其使用壽命；在技術(shù)上,就地?zé)嵩偕夹g(shù)比薄層罩面表現(xiàn)出更優(yōu)越的技術(shù)適應(yīng)性；在經(jīng)濟(jì)上,就地?zé)嵩偕夹g(shù)可以充分利用舊瀝青路面混合料,相比薄層罩面更節(jié)約資源,且運(yùn)用等效年度費(fèi)用法可以預(yù)見就地?zé)嵩偕M(fèi)用年值更小,經(jīng)濟(jì)效益較高；在社會效益上,相比薄層罩面技術(shù),就地?zé)嵩偕恍枰紤]運(yùn)輸舊的瀝青廢料以及處理廢料堆棄的問題,但是會排放較多的大氣污染物。
[Abstract]:As an important infrastructure for the development of local economy, trunk roads in mountainous countries play a more and more important role in the road network. At the same time, with the increase of the service life of roads. However, the performance of asphalt pavement in mountain area is declining day by day. Its maintenance problem has been paid more and more attention by highway builders. In view of the actual situation that the scale of highway maintenance in Guizhou mountainous area is gradually expanding and the maintenance funds are limited, in order to maintain the excellent performance of the road surface. In order to reduce the occurrence of early disease, delay the bad development of disease, prolong the service life of road and reduce the maintenance cost, the performance of asphalt pavement in mountainous area should be followed. In view of the fact that there are many kinds of pre-curing methods, such as the geothermal regeneration (super) thin layer cover, micro-surface, slurry seal, fog seal, gravel seal. It is a problem how to choose a kind of rapid maintenance method to adapt to Guizhou mountain trunk highway. Based on this, this paper puts forward a study on the technical and economic evaluation of geothermal regeneration and thin-layer covering of trunk highway in mountainous province. In this paper, the early typical diseases and development mechanism of trunk highway in Guizhou mountainous area are discussed. It is put forward that the method of technical and economic evaluation is to choose a suitable maintenance method for trunk highway in mountainous area in terms of geothermal regeneration and thin covering. Then the paper makes a systematic theoretical analysis on the technical and economic evaluation of the maintenance mode of the mountain trunk road, and points out that through the technical adaptability. The technical and economic evaluation of the maintenance mode of mountain trunk highway is carried out in three aspects of economic adaptability and social benefit. The emphasis of this paper is the evaluation of technical adaptability and economic adaptability, especially the construction of evaluation model and the establishment of evaluation system. In this paper, the AHP-TOPSIS method is used to construct the evaluation model of technology adaptation, and the equivalent annual cost method is used to analyze the economic adaptability of the maintenance mode. The social benefits are qualitatively analyzed and described. Finally based on the examples of technical and economic analysis of Guizhou two trunk roads which are maintained by geothermal regeneration and thin-layer covering technology in 2013 respectively. The results of technical and economic evaluation show that geothermal regeneration and overlay as a local rapid repair technology in asphalt pavement maintenance both improve the gradation and pavement performance of the original asphalt pavement to meet the maintenance requirements. Thus prolonging its service life; Technically, the technology of geothermal regeneration is superior to that of thin layer covering. Economically, the geothermal regeneration technology can make full use of the old asphalt pavement mixture, which saves more resources than the thin layer covering, and the annual value of the geothermal regeneration cost can be predicted to be smaller by using the equivalent annual cost method. Higher economic benefit; Compared with thin-layer covering technology geothermal regeneration does not need to consider the transportation of old asphalt waste and disposal of waste disposal but it will emit more air pollutants.
