Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an anti-peeling agent composition for asphalt pellets,

The present invention relates to a method for producing a peeling inhibitor composition for an intermediate pellet type asphalt, and more particularly, to a method for producing a peeling inhibitor composition for an intermediate pellet type asphalt which is capable of being directly introduced into an asphalt plant, Type anti-peeling agent composition for asphalt.

Damage to asphalt pavement due to water damage such as pothall due to the rapid increase of rainfall and snowfall due to climate change is the main factor. Generally, a porthole is a hole formed by infiltration of water into the surface layer of the asphalt concrete pavement and below the base layer, and it usually occurs in a thin asphalt concrete surface layer of usually 25 to 50 mm. Portholes occur mainly when water penetrates into the surface layer of asphalt concrete pavement through cracks and soft granular material layers. If the piece of asphalt pavement cracks is not adhered to the surrounding asphalt pavement material, the tires of the vehicle passing over the pavement The pores are separated from each other, and the remaining pouches are rapidly lost and the potholes are generated. Causes of portholes include: cavitation, improper packing drainage (pore water pressure), improper compaction, excessive dust and clay coating of aggregate, use of an openable friction layer (OGFC), drying of improper aggregate, weak and fragile aggregate , Overlay in worsened concrete pavement, or waterproof membrane and seal coats. When we look at the cause of the occurrence of the portholes, we can see that the sensitivity to moisture is a major factor. In order to prevent damages of asphalt pavement due to moisture, adaptive reinforcement technique is replacing the existing limestone powder used as a filler material of asphalt mixture, and the use of slaked lime is emerging.

The reason for using the waxes for molding and holding is that the wax is also effective for the middle temperature of the asphalt. In the final mixing stage of the ascon, the asphalt pellets are not only physically strong but also easily mixed with asphalt and aggregate To be mixed.

In one embodiment, the vegetable oil may be castor oil, canola oil, soybean oil, corn oil, sunflower oil, olive oil and grape seed oil. However, when the slurry is formed into a liquid phase by only maintaining the oil phase such as vegetable oil or mineral oil, there is a problem that the slaked lime pellets are not retained and easily broken after molding, and it is preferable to add the above-mentioned wax.

Therefore, in order to secure the economical efficiency of the pelletized slaked lime, it is preferable to emulsify the aforementioned middle-temperature liquid additive into a large amount of water.

In one embodiment, a surfactant is required to emulsify the oil and wax into water. As the surfactant, the following Formulas 1, 2, 3 or 4 can be used. These surfactants are all amine compounds. Depending on the modified structure, the surfactants exhibit different performances such as emulsification performance, lubricity, and compaction. They can enhance the proper lubricity, So that the stabilization of the product can be achieved.
