High-speed development of market economy, China's highway construction business development speed faster and faster. As one of the important highway maintenance and construction of the project, the construction enterprises must attach importance to the process of pouring sealant. Construction must strictly follow the relevant requirements for the construction, improve the level of construction technology, it should also regulate the construction process, the only way to ensure the scientific nature of the construction, in order to effectively improve the quality of asphalt crack process. This paper focuses on road maintenance in the process of pouring sealant sealing mechanism, construction preparation and technique are analyzed and explored.Departure thick seam penetration asphalt pavementTraditional asphalt pouring process because the asphalt materials Cold fragility and high temperature softening resistance and other characteristics, with the temperature changes in the use of crack one year after repair due to expand and contract so that the surface layer cracking again, in this case, on the road conservation and other aspects of material costs and workload will increase, we can see the traditional pitch process has been pouring asphalt pavement cracks can not be effectively addressed. Pouring sealant technology as a new technology in road maintenance, compared with traditional asphalt pouring technology can effectively avoid defects in material properties, it is also higher than in maintaining the quality and economic benefits many. Based on this, pouring sealant technology has been widely applied and promotion at this stage highway maintenance.Pavement Crack Pouring GlueSealing mechanismLiquid sealant in high temperature 193 degrees Celsius and asphalt pavement infiltration of integration, high bond strength after cooling occurs, and rely on strong elasticity, accompanied by the emergence of crack up indentation elastic deformation, to ensure that it remains sealed at all. With the development of society, people's living standards, the vehicle has increased year by year for road projects put forward higher requirements. Road crack pouring not only beautiful, practical, durable, but also clean and green, the use of road sealant pouring road with the above characteristics.The role of large road maintenance machinerySealant pouring in road maintenance and construction in preparationAutomatic suppository filling and sealing machineIn recent years, most of the road construction project, there are different degrees of pavement early damage, such as loose, oil spillage. Based on this, the relevant construction units should be strictly in accordance with the relevant provisions of the "road construction Technical Specifications", increase road maintenance efforts. Pouring sealant technology as an important technology for road maintenance, pre-construction, construction unit must be ready to work, such as material preparation, heating and other sealants, the only way to improve the overall quality of highway projects.Best Road Maintenance Machinery - Doan Machinery
