Pavement engineering of Racetracks has higher requirements on asphalt materials and construction technology, which are specifically reflected in the requirements of pavement formation, deformation resistance and durability. Compared with ordinary emulsified asphalt, modified emulsified asphalt has more advantages in high temperature stability, low temperature cracking resistance, fatigue resistance and other aspects. The construction of slurry sealing vehicle in the runway micro-surface treatment can contain, slow down and improve the crack, wear, aging, slag jumping, loose and other diseases of the asphalt pavement in the early stage. It can be waterproof, anti-slip, and cut off the root of the disease. It is of great significance to improve the quality of the pavement, extend the service cycle of the pavement and reduce the maintenance cost in the later stage. At the same time, the construction of slurry sealing layer is simple, fast, economical, and reduces the construction protection pressure. Therefore, it has been widely popularized in the construction of highway pavement.
The Micro Surfacing Paver is a new generation of slurry sealing car developed by Henan Guoji Heavy Industry in combination with years of engineering construction and equipment production practice, combined with market customer demand and feedback, which can be used in the construction process of the lower sealing layer, micro surface and fiber micro surface. It is mainly used to deal with the friction resistance reduction, cracks, ruts and other diseases on the road surface, so as to improve the skid resistance and waterproofing of the road surface. Improve road smoothness and driving comfort.
