Drain asphalt pavement has many advantages such as drain function and noise function, but it is not widely used in Korea due to loss of drain function during use and poor durability such as desorption of aggregates. However, if a binder suitable for the characteristics of drain asphalt is developed and applied, it is expected to be used continuously in the henceforward. Therefore, in this technology, the characteristics of the high-viscosity Sphalt drain binder developed to solve the problem are described. Spalt drain binder is a binder developed to produce a homogeneous mixture because it has excellent storage stability and reduces phase separation during transportation and storage.
