Description

沥青路面防水养护剂及其生产工艺和应用施工步骤技术领域本发明涉及公路工程沥青路面的防护技术.其重点是沥青路面的预防性养护及病害处理. 背景技术沥青路面由于行车性能好,施工机械化程度高,速度快,发展十分迅速,但一直也受到一些技术难题的困扰而影响到它的推广,这些技术难题主要孰是沥青路面的早期损害(未达到设计年限而出现的大面积病害),包括早期水损害、车辙、柴油污损和沥青与集料粘附性差造成的早期病害.车辙问题也是沥青路面早期病害的主要问题之一,和沥青砼的级配、基层强度或材料因素有关,路面铺好之后.车辙问题已成事实,无法改变. 因此下面只重点简述水损害、柴油污损及沥青粘服性问题.一、早期水损害指沥青铺体由于长期浸水受损,未达到设计年限而提前出现的各种病害:路面设计中虽然已考虑了结 Waterproofing agent asphalt pavement maintenance and construction technology field step production process and application of the invention relates to protection technology of highway asphalt pavement engineering. The focus is on preventive maintenance of asphalt pavement and disease treatment. BACKGROUND asphalt pavement due to the good performance of traffic, construction mechanization a high degree of speed, developed very rapidly, but has also been plagued by technical problems and affect its promotion, these technical problems mainly what the early damage of asphalt pavement (not meet the design life of the emergence of a large area of ​​disease), one of the major problems include the early water damage, rutting, diesel and early fouling of asphalt with aggregate diseases caused by poor adhesion. rutting problems are early disease asphalt pavement, and graded, the strength of the base layer or material factors related to asphalt concrete, after the paved road. rutting problems is a fact, can not be changed. Therefore, the following only briefly focus on water damage, deface diesel and asphalt sticky service issues. First, the early water damage refers to the asphalt paved flooding damaged due to the long body, does not meet the design life the early appearance of various diseases: Pavement design Although considered taking 排水和路表排水问题,但由于空隙率的存在,加上施工中级配设计,混合料制备、运输、摊铺及碾压作业过程中存在的问题,会造成局部或大面积的、随机或有规律的透水现象,特别在冷热接头及横坡两端,普遍存在严重透水现象,而水一旦浸入沥青铺体,排空极为困难,实验表明,空隙率在4. 3〜6.2的路面(横坡2%,纵坡W。)连续下雨两天后排空时间需要7〜1G天,这就意味着而季沥青铺体将长期处于水及水气的浸泡过程中.在车辆动荷载反复作用下,新青膜与集料开始剥离,渐渐的,集料开始松散掉粒,最后形成坑槽.而且,经过路面开挖检查发现,水损害往往是从新青下面层开始的.由于水分进入新青路面,滞留在基层上面,沥青砼下部空隙中充满水分的时间要比上面层时间长的多,给水损害提供了条件,在长时间的交变应力作用后,当表层新青仍 Drainage and road surface drainage problems, but due to the presence of porosity, coupled with mid-level construction design, preparation of mixes, transportation, paving and rolling operation process problems, can cause partial or large, randomized or permeable regular phenomenon, especially in the hot and cold ends of the joint and cross slope, widespread severe flooding phenomenon, while immersed in water once the asphalt paved, drained extremely difficult, experiments show that the porosity of the road 4. 3~6.2 (cross 2% slope, longitudinal slope W.) after two days of continuous rain emptying time required 7~1G days, which means that while the body lay asphalt season will be a long process of immersion in water and water vapor. repeated the role in the dynamic load of the vehicle , the aggregate Xinqing film peeling is started, gradually, beginning loose aggregate grain out of the last pit formation. Moreover, after examination revealed road excavation, water damage is often started from the underlying layer xinqing Since the new water green road, above the residence in the base layer, the top layer of asphalt concrete time is much longer in the lower portion of the gap filled with water than the time, provides feedwater damage conditions after a long period of alternating stress, when the surface is still xinqing 松散时,下面层集料已与沥青完全分离,沥青是沥青,集料是集料,处于完全松散状态,沥青混合料不再成为一个整体,而且含水量增大,面层容易被推移,这时集料在荷载作用下也会对基层表面产生挤压,基层上部的透层、封层也会受影响而产生损坏,基层的土质部分便成为泥浆并透过沥青面层挤出,形成唧浆,在而天会迅速扩展成坑槽.工程中往往用减小沥青砼空隙率的办法来减少渗水速度,但是它的作用是很有限的, 对于密集配沥青砼来说,空隙率小于极限值(2%~4%)时,沥青在受热膨胀时无适当空隙容纳将容易产生泛油,并导致混合料推移和车辙变形.根据美国战略公路研究计划的研究结果表明,沥青路面最合理空隙率为4%,也就是说,只要用沥青混凝土,就会有空隙率的存在,而只要有空隙率就会导致水的渗入,空隙率小,水的渗入速度慢 In bulk, the underlying layer of aggregate is completely separated from the bitumen, asphalt, the aggregate is the aggregate, in a fully loose state, no asphalt mixture as a whole, and the water content is increased, the surface layer is easily passage, which when the aggregate will be produced at the surface of pressing load on the base layer, the base layer through the upper layer, the sealing layer may be affected and cause damage, soil slurry becomes part of the base layer and extruded through the asphalt surface to form a jack pulp, day in and quickly expanded into the pits. engineering approach is often used to reduce the porosity of asphalt concrete to reduce water seepage rate, but its role is very limited, for dense graded asphalt concrete, the porosity is less than the limit value (2% to 4%), while no pitch suitable gap to accommodate the thermal expansion prone to weeping, and the passage leading to mix and rutting. according to the study of the U.S. strategic Highway Research Program showed that the most reasonable asphalt pavement void 4%, that is, as long as concrete, there will be the presence of porosity, but the porosity will result as long as infiltration of water, a small void ratio, the slow rate of water infiltration 些,但排空速度更慢,更重要的是有出现泛油的风险.近期有个别企业在尝试用一种油膏来处理沥青的老化再生问题,该方法希望通过涂料中的轻质油分作用于铺体老化的沥青,实现一定程度的沥青再生功能,但该材料最大的问题是抹平了沥青表面的构造深度,极大的降低了抗滑性能,在一些重要工程试验中已造成车辆事故率的提高及钢桥面新青铺装层的严重破坏.该种类型的材料不具备在公路上使用的最基本的条件.完全避免水进入沥青铺体是解决这个问题的关键.因此,如果能研制出一种液体涂料,作为上封层(很薄的)涂布新青铺体表面,既能堵塞表面的渗水微空隙,并在表面形成完整保护膜,隔断水的浸入途径,而且该材料的软化点必须大于75'C,不产生副作用,即在太阳光下晒不软化、不明显影响表面抗滑性能及内部空隙率,这将能从根本上解 Some, but emptying slower, more importantly, there is the risk of weeping appearance. There are individual enterprises in recent attempts to regenerate aging ointment to deal with the problem in a bitumen, which hopes to divide the role of light oil coating asphalt aging body shop, to achieve a certain level of asphalt recycling function, but the biggest problem that the material is a smooth asphalt surface texture depth, greatly reducing the skid resistance, has caused vehicle accidents in a number of important engineering tests improve and serious damage to the steel deck pavement Xinqing rate. this type of material does not have the basic conditions of use on the road. completely avoid water from entering the body is a key asphalt paved solve this problem. So, if a liquid coating material can be developed, as the sealing layer (thin) coating the surface Xinqing shop, both blockage of water seepage microvoided surface, and form a complete surface protective film, blocking water infiltration route, and the the softening point of the material must be greater than 75'C, no side effects, i.e., drying in the sun does not soften significantly affect the performance of sliding surface and internal porosity, which solution will fundamentally 水损害的问题.到目前为止,国内外学术界及工程界仍未有相关的在公路沥青路表面整体喷涂防水养护剂,用于预防沥青路面早期水损坏及提高表层使用性能,延长路面使用寿命的报道.二、 柴油污损问题越来越严重,已引起业主及专冢的广泛关汪: 特别是省际公路及大城巿过境公路,柴油车特别多,车况好坏参差不芥,很容易造成柴油污染;城巿红绿灯路口及停车处,也普遍受到柴油的污染.路况调查及试验研究成果证明:沥青砼对柴油很敏恐,路面受柴油污染后会很快起坑槽;试验室用柴油作沥青马歇尔试件耐油试验(常温下,试件置于O'柴油中浸泡12小时后晾干称重),其重量损失为2.8%,表面沥青膜完全溶解,见不到沥青痕迹,表面呈现松散状态.三、 新青粘附性差易造成的病害:只解决铺体的水损害还不够.沥青粘附性能(对集料的粘结力) The problem of water damage. So far, domestic and foreign academic and engineering still relevant in the overall highway asphalt road surface waterproofing coating curing agent for the prevention of early water damage of asphalt pavement surface and improve performance, extend the pavement life reports Second, diesel fouling problem is getting worse, the owners and has caused widespread off the mound Wang special: in particular, inter-provincial highways and transit road big cities, particularly large number of diesel vehicles, not mustard mixed condition is good or bad, it is easy to caused by diesel pollution; Town traffic lights and parking, are generally contaminated diesel road survey and experimental research to prove: asphalt concrete for very sensitive diesel fear, Pavement soon after diesel contamination from pits; laboratory use asphalt Marshall specimens for diesel oil test (at room temperature, the specimen was placed dry weighed 12 hours O 'immersion in diesel fuel), the weight loss was 2.8%, the surface was completely dissolved bituminous membranes, bituminous see marks, surface presents three loose state, disease xinqing easily cause poor adhesion: only address water damage asphalt paved bodies enough adhesive properties (adhesion to the aggregate). 也是造成沥青混砼早期损坏的主要原因之一,由于集料颗粒完全靠沥青粘结在一起,而普通沥青的粘附性能有限,在常温下使用时,受外界条件影响,沥青容易变硬发脆,呈现脆性材料特性, 因而在车轮剪切作用下,易造成剝落,普通沥青混凝土路面不到一年沥青膜即开始剥落泛白,局部承受动荷载较大部位已开始出现麻面、掉粒现象.提高沥青粘附性的通行做法是在沥青中掺加抗剥落剂(含水泥、矿粉等)或将沥青进行改性.前者在工程实际应用中的作用不是特别明显;后者虽提高了粘附性和杌老化性能,透水少一些,但滲水现象同样存在.实践证明,改性沥青砼也同样存在着早期水损害现象,而且造价很高,推广有一定难度.在公路养护中,处理由于粘附性差所造成的路面局部早期疲劳病害(包括龟裂、网裂、松散、掉粒等)的方法一般用乳化沥 Asphalt concrete mix is ​​one of the main causes of early damage, since complete aggregate particles bonded together by the asphalt, the asphalt is limited ordinary adhesion property, when used at room temperature, influenced by external conditions, asphalt easily becomes hard fat crisp, brittle material exhibits properties under shear and thus the wheel, could easily lead to spalling, less than a year of ordinary asphalt pavement peeling bituminous membranes began to whiten, local site subjected to dynamic loading has begun to appear larger pitted surface, grain out . phenomenon is common practice to improve the adhesion of the asphalt in the asphalt adding anti-stripping agent (including cement, slag, etc.) or modified bitumen role in the practical application of the former is not particularly significant engineering; the latter, although improved the adhesion and stool aging properties, less permeable, but water seepage phenomenon also exists. practice has proved that the modified asphalt concrete also exists the phenomenon of early water damage, and the high cost, promote a certain degree of difficulty. highway maintenance, method of treating diseases due to the road surface locally early fatigue caused by poor adhesion (including cracking, crack mesh, loose grain out, etc.) is generally asphalt emulsion 青充填封闭的办法处理,但这种方法临时处理了裂缝的严重渗水问题,但由于乳化沥青软化点低,易造成泛油,削氏了路面的使用性能.只宜作为对局部小面积存在严重病害的路面的临时防水处理.稀浆封层罩面是近年来迅速发展的一种路面维修技术,它在沥青路面上用细粒式级配碎石或沙作集料,以乳化新青(或改性乳化沥青)为粘结剂,加填料和水冷拌后用稀浆封层机摊铺成新青表处薄层,厚度3-10mm,用于封闭表面空隙、裂缝,改善抗滑性能和恢复提高路表面行车功能.但由于技术仍不太成熟,耐久性欠佳,施工费用高、难度大,对推广应用有一定影响,而且仍未能有效解决自身渗水所造成的水损害问题. 发明内容:本发明的第一个目的是研制一种沥青路面防水养护剂的配方及生产工艺,将这种养护剂喷涂在公路新青路面或其它相关部位上,可预 Green closed approach to filling, but this method of handling a temporary water seepage problem serious cracks, but due to the low softening point emulsified asphalt, easily lead to weeping, s cut the pavement performance. Should be taken only as a small local area serious temporary waterproofing pavement disease. slurry seal overlay a road maintenance in recent years, the rapid development of technology, which uses fine-grained graded gravel or sand as aggregate in asphalt, emulsified Xinqing ( emulsified asphalt or modified) as a binder, a filler and a water-cooled mixed after adding a thin layer xinqing surfacing machine paving slurry seal with a thickness of 3-10 mm, for the closing surface voids, cracks, improved skid resistance and restore the road surface to improve driving features, but because technology is still not mature enough, poor durability, high construction costs, difficult and have an impact on the application, but can not effectively solve the problem of water damage caused by water seepage itself. Summary of the invention: a first object of the present invention is to develop an asphalt waterproofing curing agent formulation and manufacturing process, such a curing agent sprayed on the road surface or other road xinqing relevant parts, can be pre- 沥青砼的早期水损害,抗柴油污损, 并增强沥青砼表层的路用性能,从而延长路面使用寿命.本发明的第二个目的是提出一种将上述沥青路面防水养护剂喷涂在高速公路沥青路面上的施工工艺技术,使该产品的路用性能得到充分发挥.本发明的第三个目的是提出将上述沥青路面防水养护剂喷涂在高速公路沥青路面的柔性涂料厚度检测装置及检测方法.本发明的第一个目的可通过如下途径来实现:一种新青路面E?水养护剂,其特征在于有如下重量份比例的材料组成:沥青ioo橡胶粉2~25树脂3~10橡胶2~16交联剂2~10偶联剂1~ 6复合乳化剂1~20抗老化剂适量活化剂30 ~ 300起泡剂适量消泡剂适量所述的橡胶粉系旧轮胎经加工后成超细粉沫状态; 所述的树脂为HMA聚合物; 所述的橡胶为SBS ;所述的乳化剂包括阳离子乳化剂、聚氨基硅油和少量无机无机细集料等复合加工而成 Early asphalt concrete of water damage, the anti-offset diesel fuel, asphalt surface and enhance the concrete road performance, thus prolonging the life pavement.
