METHOD FOR MANUFACTURING REPAIR MATERIAL FOR PAVEMENT WITH FINE POWDER AND REPAIR MATERIAL FOR PAVEMENT WITH FINE POWDER MANUFACTURED USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a repair material capable of handling a variety of small scale repair points such as cracks and holes, including micro pores generated in a road repair surface or water resistant layer, by improving fluidity to better poor viscosity during repair; and capable of preventing flash phenomena at high summer temperatures after construction, which exhibits impact resistance, viscoelasticity, plastic deformation, and the like, at an early stage, and which maintains an excellent condition for a long period of time.;SOLUTION: A repair material for pavement with fine powder is comprised of a mixture of 10-30 wt.% of a lubricant waste liquid or a lubricant, 0.5-3 wt.% of synthetic silica, 35-55 wt.% of blown asphalt having a penetration of 10-30, 12-30 wt.% of straight asphalt having a penetration of 100-200, 1-4 wt.% of rosin, 12-25 wt.% of slaked lime, and 1-6 wt.% of bentonite.;SELECTED DRAWING: None;COPYRIGHT: (C)2019,JPO&INPIT
