【摘要】：隨著國(guó)家公路建設(shè)投入的加大，西部地區(qū)公路不斷興建。由于公路路基地質(zhì)、水文條件的影響以及動(dòng)靜荷載長(zhǎng)期作用，公路瀝青路面受到損傷，裂縫、車轍、松散、泛油等病害的出現(xiàn)，嚴(yán)重影響公路的運(yùn)營(yíng)壽命和行車安全。因此，對(duì)瀝青路面路面性能狀況進(jìn)行評(píng)價(jià)以及養(yǎng)護(hù)對(duì)策研究具有重要意義。 S102線K0+000～K32+275烏魯木齊迎賓路至五家渠段公路自投入使用以來，路面在車輛荷載重復(fù)作用、瀝青老化及溫度應(yīng)力等不利因素作用下出現(xiàn)了橫向裂縫、縱向裂縫、松散、車轍等病害。通過對(duì)路面病害調(diào)查評(píng)價(jià)以及微表處預(yù)防性養(yǎng)護(hù)技術(shù)研究，設(shè)計(jì)出最佳養(yǎng)護(hù)方案。首先，論文對(duì)S102線K0+000～K32+275烏魯木齊迎賓路至五家渠段出現(xiàn)的病害進(jìn)行調(diào)查，采用路面使用性能指數(shù)（PQI）并結(jié)合路面結(jié)構(gòu)強(qiáng)度指數(shù)（PSSI）評(píng)定結(jié)果對(duì)路面技術(shù)狀況進(jìn)行綜合評(píng)定，并對(duì)路面主要病害的成因進(jìn)行分析，在此基礎(chǔ)上，得到整個(gè)路段瀝青路面的狀況，為預(yù)防性養(yǎng)護(hù)方案設(shè)計(jì)提供數(shù)據(jù)。 通過對(duì)養(yǎng)護(hù)方案經(jīng)濟(jì)效益、養(yǎng)護(hù)標(biāo)準(zhǔn)以及稀漿封層、微表處、碎石封層、霧封層預(yù)防性養(yǎng)護(hù)措施等內(nèi)容進(jìn)行研究，選擇尋找成本較低、效果佳的微表處封層技術(shù)作為該項(xiàng)目的瀝青路面養(yǎng)護(hù)方案。其次，對(duì)瀝青路面微表處養(yǎng)護(hù)的設(shè)計(jì)方法以及對(duì)材料要求、混合料級(jí)配、材料用量的范圍進(jìn)行研究；在此基礎(chǔ)上，進(jìn)行配合比試驗(yàn)研究，根據(jù)試驗(yàn)結(jié)果確定微表處混合料的最佳配合比為：石料：乳化瀝青：水：填料=100：12.7：10：2。最后，，以新疆S102烏魯木齊迎賓路至五家渠段大中修工程為例，提出了微表處養(yǎng)護(hù)方案，對(duì)技術(shù)應(yīng)用過程進(jìn)行施工工藝、施工質(zhì)量進(jìn)行控制，針對(duì)施工過程遇到的各種問題，提出相應(yīng)的處治方法。 通過微表處預(yù)防性養(yǎng)護(hù)技術(shù)在本工程的應(yīng)用研究，對(duì)提高行車舒適性、預(yù)防公路病害的進(jìn)一步發(fā)展、延長(zhǎng)道路使用壽命、降低道路養(yǎng)護(hù)費(fèi)用都具有十分重要的意義。道路養(yǎng)護(hù)后路面狀況表明，微表處技術(shù)在本項(xiàng)目的應(yīng)用成功的，可在該地區(qū)推廣使用。
[Abstract]:With the increase of the national highway construction investment, the western region highway construction unceasingly. Due to the influence of highway subgrade geology, hydrological conditions and static loads for a long time, asphalt pavement is damaged, cracked, rutted, loose, flooding oil and other diseases, which seriously affect the operation life and driving safety of highway. Therefore, it is of great significance to evaluate the performance of asphalt pavement and to study the maintenance countermeasures. Since the highway between Yingbin Road and Wujia Canal in Urumqi has been put into use, Under the action of repeated vehicle load, asphalt aging and temperature stress, the pavement has many diseases, such as transverse crack, longitudinal crack, loose, rutting and so on. Through the investigation and evaluation of pavement diseases and the study of preventive maintenance technology at microsurfacing, the best maintenance scheme is designed. Firstly, the paper investigates the diseases in the section between Yingbin Road and Wujiaqu of K0000K32275 Urumqi on S102 Line. The pavement technical condition is evaluated synthetically by using the pavement performance index (PQI) and the evaluation result of pavement structure strength index (PSSI). Based on the analysis of the causes of the main pavement diseases, the condition of the asphalt pavement of the whole section is obtained, which provides data for the design of the preventive maintenance scheme. By studying the economic benefits, maintenance standards, slurry sealing layer, microsurface, gravel seal and preventive maintenance measures of fog seal, the cost of the maintenance scheme is low. The effective microsurfacing sealing technology is used as the asphalt pavement maintenance scheme of the project. Secondly, the design method of asphalt pavement micro-surface maintenance and the range of material requirement, mixture gradation and material dosage are studied. According to the test results, the optimum mix ratio of the mixture is determined as follows: stone: emulsified asphalt: water: filler 100: 12.7: 10: 2. Finally, taking the large and medium repair project from Yingbin Road to Wujiaqu in Urumqi, Xinjiang as an example, the maintenance scheme of micro-surfacing is put forward, the construction technology and construction quality are controlled during the application of the technology, and the various problems encountered in the construction process are pointed out. The corresponding treatment methods are put forward. Through the application of microsurfacing preventive maintenance technology in this project, it is of great significance to improve the driving comfort, prevent the further development of highway diseases, prolong the road service life and reduce the road maintenance cost. The pavement condition after road maintenance shows that the application of microsurfacing technology in this project is successful and can be popularized in this area.
