Description

Binder Composition, Primer Composition and Skid-proof Mixture for Road Pavement

The present invention relates to a binder composition for road pavement, an anti-slip pavement mixture in which aggregate is mixed, and a primer composition for tightly bonding the binder composition or the anti-slip pavement mixture and the road surface. Specifically, the binder composition and the primer composition of the present invention have a bisphenol A type epoxy resin as a main component and mix and cure it with a polyamine resin, but a reactive epoxy diluent and a dimer acid-modified epoxy resin are mixed to form a low temperature. The present invention relates to a road paving material that improves workability by allowing a low viscosity to be expressed during pavement.

The road pavement material of the present invention can easily and quickly perform the maintenance according to the breakdown of the asphalt pavement, and can be installed in the section where the required sliding resistance is not secured due to the geometry and traffic characteristics of the road to improve the friction force There is an advantage.

Among the various causes of traffic accidents, road friction is a factor that directly or indirectly affects traffic safety, which is very important for evaluating road safety. In the case of highways, traffic accidents caused by sliding of roads occur on average over 1,200 cases every year.

Various methods have been attempted to solve this problem, but recently, there has been a problem in commonality of road paving materials. Since the first use of modified asphalt in Korea in the mid 90's, it is gradually being used as a way to reduce temperature deformation due to plastic deformation and temperature difference. Development is in progress.

In addition, many attempts have been made to improve the construction method. As a new construction method for construction crack control, Echelon Paving, a construction method that suppresses the joint in the longitudinal direction by two-lane simultaneous laying, and heterogeneity due to temperature deviation An example is the Material Transfer Vehicle (MTV) method, which is a measure to improve packing quality by preventing compaction and securing a uniform installation temperature.

However, it is not possible to overcome the limit of the common performance even with this method. The conventional pavement and the quality assurance in the plant, such as asphalt and aggregate, do not have an organic system. This is because quality improvement cannot be achieved, and a new concept is urgently needed for such materials and construction methods.

On the other hand, recent trends in pavement technology development have focused on reducing noise and introducing rainwater quickly to ensure the driver's pleasant driving performance and reducing noise around roads. The trend is to focus on functional aspects, such as aesthetics and visibility.

However, there are no fundamental solutions to problems such as portholes due to deformation, breakage and stormwater penetration. As a way to solve these problems, new concepts of packaging materials and packaging methods have been studied. It is a packaging method using a polymer composition.

At present, the polymer composition as a packaging material introduced in Korea has a method of applying a specially processed epoxy resin to the surface of the bridge steel plate to form a waterproof and anticorrosive layer, and by spraying silica sand to form an anti-slip layer, and then attach ascon on it. However, unlike the packaging material of the present invention, the above method is only an adhesive layer utilizing the adhesive performance and the waterproof performance of the epoxy material, and the use of the substrate and the surface layer as a packaging structure is inappropriate. In addition, similar methods are just using the material of the impermeable layer as a method for preventing the durability of the bridge, so far the packaging method using the polymer composition has not been introduced in Korea.

Above all, the construction using the epoxy resin has a problem that the workability is remarkably degraded due to the high viscosity of the resin itself at a low temperature, it is difficult to secure a suitable pot life, and takes too much time for complete curing.
