【摘要】：山區(qū)國省干線公路作為發(fā)展地方經濟重要的基礎設施,在公路路網中發(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)護問題也越來越受到公路建設者的普遍關注。針對貴州山區(qū)公路養(yǎng)護規(guī)模逐步擴大而養(yǎng)護資金又有限的實際情況,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)護成本,應跟據山區(qū)公路瀝青路面的使用性能,適時選擇符合其特點的技術對其進行預防性養(yǎng)護。鑒于目前的預養(yǎng)護方式有多種,如就地熱再生、(超)薄層罩面、微表處、稀漿封層、霧封層、碎石封層,如何選擇一種適應貴州山區(qū)干線公路的快速養(yǎng)護方式成為一個問題�；诖�,本文提出對山區(qū)國省干線公路進行就地熱再生和薄層罩面的技術經濟評價研究。 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)展機理,提出通過技術經濟評價的方法在就地熱再生和薄層罩面中選擇一種合適山區(qū)干線公路養(yǎng)護是養(yǎng)護方式,然后對山區(qū)干線公路養(yǎng)護方式的技術經濟評價進行了系統(tǒng)的理論分析,指出通過技術適應性、經濟適應性和社會效益三個方面對山區(qū)干線公路的養(yǎng)護方式進行技術經濟評價。 本文的重點是技術適應性評價和經濟適應性評價,特別是技術適應性評價模型的構建和評價體系的建立,本文用AHP—TOPSIS方法構建技術適應型評價模型,再應用等效年度費用法等方法分析養(yǎng)護方式的經濟適應性,社會效益進行定性分析描述。最后依托2013年分別運用就地熱再生和薄層罩面技術進行養(yǎng)護的貴州兩條干線公路進行技術經濟分析實例論證。 技術經濟評價結果表明：地熱再生和薄層罩面作為瀝青路面養(yǎng)護中的一種就地快速修復技術,它們都改善原瀝青路面級配和路面路用性能,達到養(yǎng)護要求,從而延長其使用壽命；在技術上,就地熱再生技術比薄層罩面表現出更優(yōu)越的技術適應性；在經濟上,就地熱再生技術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,且運用等效年度費用法可以預見就地熱再生費用年值更小,經濟效益較高；在社會效益上,相比薄層罩面技術,就地熱再生不需要考慮運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.
