Manufacturing method of coal tar-based room temperature road repair material for porthole emergency maintenance and Construction method of road repair material thereof

摘要

The present invention relates to a method for manufacturing a room temperature road repair material based on coal tar for rapidly repairing a pothole and a method for constructing a room temperature road repair material thereof, which comprise: a step (S1) that an aggregate for road repair is prepared in a uniform size with the diameter being 13mm or less; a step (S2) that a binder is manufactured for attaching the pieces of aggregate and maintaining the attached state thereof in a pothole; a step (S3) that the aggregate and the binder prepared in the step (S1) and the step (S2) are placed in a mixer with an inner temperature of 20-60°C before being mixed for 10-12 minutes and being cooled at room temperature of 15-25°C for 5.5-6.5 hours, to manufacture a room temperature road repair material; and a step (S4) that the manufactured room temperature road repair material is inserted into a sack, thereby completing the road repair material.
