The main purpose
Polyester fiber is mainly used in the asphalt road surface, the old mask of the asphalt surface, old cement road surface, road surface cold patch, seam filling and bridge deck pavement, toll roads, etc.
The construction technology
Adding KWS polyester fiber asphalt concrete construction technology and original asphalt concrete construction technology of basic same, but at the same time, to join in a blender aggregate dosage according to the provisions of adding asphalt concrete reinforced with polyester fiber mixer, and with aggregate dry mix 30 to 60 seconds, and then add to mix asphalt mix 30 to 60 seconds.For continuous drum mixer and partial batching type mixing equipment, mixing process is different.Continuous drum mixer, fiber must be along with aggregate before completely dry aggregate to join.Partial batching type mixing equipment, according to the ratio of engineering, directly adding fiber in the process of stirring gently in the aggregate.
