Description

一种水性道路沥青复原剂及其制备方法技术领域 An aqueous asphalt road restoration and preparation method thereof Technical Field

[0001] 本发明涉及一种可美化和修复浙青路面老化、麻面、微小裂缝、渗水等早期病害, 能迅速渗透浙青路面表层,密闭路面、治理麻面、稳住松散,弥合微小裂缝,达到封水,改善道路抗滑能力和优美路面外观的道路浙青复原剂及其制备方法,属浙青路面维护和修理相关领域。 [0001] The present invention relates to an landscaping and microcracks Zhejiang green road repair aging, disease early Ma face, micro-cracks, water seepage, can rapidly penetrate Zhejiang Green road surface, road closed, Ma surface treatment, to stabilize loose, bridge , to seal water, improve the recovery agent roads Zhejiang green and preparation of road pavement skid resistance and beautiful appearance, is Zhejiang green road maintenance and repairs related fields.

背景技术 Background technique

[0002] 随着浙青路面越来越广泛应用到高速公路和城市道路建设中,路面老化、裂缝、麻面、松散、砂化、水损坏等浙青路面常见病害是影响道路正常使用和缩短使用寿命的最大杀手,如不及时进行综合治理,会加速道路损坏,加大道路维修成本,影响道路正常运营,造成重大经济损失。 [0002] As more and more widely used in Zhejiang Green road to the highway and urban road construction, road aging, crack, pockmarked face, loose of sand, water damage, etc. Zhejiang Green road of common diseases affecting normal road use and shorten the biggest killer of life, if not comprehensive management, will accelerate the damage to roads, increase road maintenance costs, affecting the normal operation of the road, causing heavy economic losses. 此时路面在结构上并没有大的损坏,对行车的影响不大。 At this point in the pavement structure and no major damage has little effect on the traffic. 一般在这种情况下,路面综合质量指数在良及良以上,路面状况指数PCI在80〜95之间。 Typically, in this case, Pavement Quality Index over good and good, pavement condition index PCI between 80~95. 此时是对路面进行预防性养护的最佳时机。 At this point the road is the best time to carry out preventive maintenance.

[0003] 预防性养护具有施工方便、施工期短、社会效益和经济效益良好等特点。 [0003] preventive maintenance easy construction, short construction period, good social and economic benefits and so on. 预防性养护方法很多,如雾封层、微表处、稀浆封层和薄层罩面等。 Preventive Maintenance many ways, such as fog seal, micro-surfacing, slurry seal, and a thin layer of overcoat like. 这一系列的技术已在美国、加拿大和欧洲的一些国家得到了广泛的应用,并取得了巨大经济和社会效益。 This series of technology has been widely applied in some countries, the United States, Canada and Europe, and has achieved great economic and social benefits. 国外经验表明,对道路米取计划性养护措施,提闻路面耐久性,可以有效延长公路使用寿命,提闻道路运营效率和发挥道路本身的经济、社会效益。 Foreign experience shows that planned to take conservation measures on road meters, mention smell pavement durability, can effectively extend the service life of the road, carrying the smell roads operational efficiency and play road itself economic and social benefits. 对道路前期投入I元钱,可以节省后期6 - 10元的投入。 I put on the road early dollars, you can save late 6--10 yuan investment. 然而在国内的推广应用中,微表处、稀浆封层和薄层罩面等技术对设备、施工工艺、技术人员素质比较严格。 However, in the promotion of domestic applications, micro-surfacing, slurry seal and thin overlay technology more stringent equipment, construction technology, technical quality of personnel. 同时,在采用这些技术处理后,还会带来环保、废料处理、能源浪费、 重铺交通路面白线,封路时间过长引起的交通及社会经济的损失等一系列问题。 Meanwhile, after the adoption of these technologies deal with, but also bring environmental protection, waste disposal, energy waste, heavy traffic roads paved white line, a series of traffic problems and socio-economic losses such as road closures caused by too long. 目前国内外对环保、高性能的预防性养护材料已开始研究和应用。 At home and abroad for environmental protection, high-performance materials has begun to study preventive maintenance and applications. 美国研制的Pavement Dressing Conditioner (简称F1DC,美国专利号5,580, 603)是一种预防性的浙青路面再生剂,然而该材料对处理已出现3〜5mm的裂缝、浙青老化脱落、严重松散等病害的效果不是太明显。 US-developed Pavement Dressing Conditioner (referred F1DC, U.S. Patent No. 5,580, 603) is a preventive agent Zhejiang green pavement recycling, however, the treated material is cracked and 3~5mm, Zhejiang green aging off, serious the effect of loose and other diseases are not too obvious. 国内也开始了该类材料的研制和应用,但未见应用报道。 China also began the development and application of such materials, but no application reports.

[0004] 近年来,随着国家相关政策的出台,交通各级部门对道路的预防性养护极为重视, 道路预防性养护市场逐渐扩大。 [0004] In recent years, with the introduction of relevant national policies, traffic departments at all levels to attach great importance to preventive maintenance of roads, road preventive maintenance market gradually expanding. 国内近20%的浙青路面处于预养护阶段。 Nearly 20% of the domestic Zhejiang Green road in the pre-maintenance phase. 据预测,最近I〜 2年市场对该类养护材料的需求量约3万吨/年,在3〜5年的市场成长期,市场对该类材料的需求可达到5〜10万吨/年。 It is predicted that market demand in recent I~ 2 maintenance materials for the class of about 30,000 tons / year, the market is growing at 3 to 5 years, the market demand for this type of material can reach 5 to 10 million tons / year . 预计在10年左右,本项目的市场需求总量将在30万吨/年左右,市场总值达120亿元。 Is expected in about 10 years, the total market demand of the project will be about 30 million tons / year, the market value reached 12 billion yuan.

[0005] 随着国内环保逐渐升温,以及社会和群众对公路交通的需求越来越高,高等级公路及城市道路预防性养护市场对预防性养护材料的粘附性能、耐久性能、美化修复路面等功能提出了更高要求。 [0005] With the gradual warming of domestic environmental protection, and social needs of the masses and the increasing road traffic, highway and city roads preventive maintenance preventive maintenance market adhesion properties of the material, durability, beautify road repair and so put forward higher requirements. 然而国内市场上以乳化浙青、改性乳化浙青为代表的低档浙青路面预防性养护材料仍占较大比例,而高性能、环保浙青复原剂材料处于空白。 However, the domestic market in order to emulsify Zhejiang blue, green modified emulsion Zhejiang as the representative of Zhejiang low-grade green pavement preventive maintenance materials still account for a large proportion of high-performance, environmentally friendly green recovery agent Zhejiang material in the blank.

发明内容[0006] 本发明根据浙青道路养护朝环境友好型发展的趋势及市场上现有预养护材料所存在的不足,目的在于提供一种水性道路浙青复原剂及其制备方法,用于美化路面外观,提高道路抗滑能力和防水性能,解决浙青老化、松散、麻面、细小裂缝、渗水等浙青路面早期病害,并预防或遏止病害发展和蔓延,从而延长道路寿命。 SUMMARY OF THE INVENTION [0006] According to the present invention is less than the trend towards road maintenance Zhejiang green and environment-friendly development and maintenance materials available in the market pre-exists, and aims to provide an aqueous cyan Zhejiang road restoration and its preparation method for landscaping road appearance, improve road skid resistance and water resistance, Zhejiang green solve aging, loose, Ma face, small cracks, water seepage Zhejiang green road early disease, and prevent or curb the development and spread of diseases, thus extending the life of the road.
