PURPOSE : Provided are road paving materials having characteristics of earth such as water permeation, heat absorption and weather resistance by using earth as main materials and solidifying materials.
CONSTITUTION : The road paving materials comprises 100kg of fine aggregates made of earth, 5-16kg of solidifying materials, 13-17kg of water, and 0.3-1kg of Eco-Path System(EPS) solution obtained by dissolving high concentration of alkali metals(K, Ca) and metal salts in water. The footway is made by spreading sand soil as main paving materials over the surface of a road in a 3-5 cm thickness, keeping maximum dry density of Pdamx x 90(%). The carriage way is made by spreading crushed stone as main paving materials over the surface of a road in a 5-10cm thickness, keeping maximum dry density of Pdamx x 96(%).
