▎ 摘  要

NOVELTY - Semi-flexible asphalt mixed material filled with metakaolin base polymer comprises a large-pore open-graded asphalt mixed material and metakaolin base polymer grouting material, where the large-pore open-graded asphalt mixed material is fiber modified asphalt, mineral powder and aggregate as main raw materials, metakaolin base polymer grouting material uses alkali excitant, metakaolin, graphene, styrene-butadiene emulsion, silane coupling agent, fly ash and sand as main raw materials. USE - Semi-flexible asphalt mixed material filled with metakaolin base polymer. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing a semi-flexible asphalt mixed material filling metakaolin base polymer, involving: (1) Using fiber-modified asphalt, mineral powder and aggregate as main raw material, preparing Marshall test piece with porosity of 20-30%, obtaining large-pore open-graded asphalt mixed material; (2) Preparing metakaolin base polymer grouting material into the Marshall test piece; (3) Starting the vibrator under the vibration condition until the slurry cannot completely permeate from the surface; (4) Removing the ground polymer slurry remained on the surface of the asphalt test piece until the surface of the base body is exposed; and (5) Maintaining and molding.
