Development of Color Pavement in Korea

Abstract

A development of color pavement in Korea is presented. An examination of pavement materials used, preparation of specimen, comparison tests between regular and colored mixture, mixing at asphalt plant, and placing colored mixtures in field is included. A synthetic resin binder with light yellow color was developed, and proved compatible for colored pavement through the several comparison tests: Marshall stability test, wheel tracking test, ravelling test, and accelerated weathering test. For the pigment, several different inorganic products were used: Fe2O3(IOR),Fe2O3(IOY),Cr2O3, and ultramarine blue. The mixing operation and paving method of color mixture were same as regular asphalt concrete mixture, but the quantity of pigment replaced that of mineral filler. After a successful trial placing, the mixture was placed in the plaza of Great Seoul Children Park and the sidewalk of new Banpo Bridge. The utilization of color pavement will provide better roadway environment and traffic safety, and will be accelerated by the beautification plan for 1986 Asian and 1988 World Olympic Games in Seoul.
