INJECTION MATERIAL FOR SEMIFLEXIBLE PAVING AND SEMIFLEXIBLE PAVING

摘要

PROBLEM TO BE SOLVED: To provide an injection material for semiflexible paving having excellent freeze-thaw resistance as well as excellent in development of initial strength and a semiflexible paving using the injection material.SOLUTION: There are provided an injection material forming a semiflexible paving with compressive strength of material age after injection of 2 hours of 5 N/mmor more, having cement amount of 55 wt.% or more, containing a fine aggregate, a rapid hardening material, a powder resin, a water-reducing agent, and an AE agent, and having water powder ratio of cement milk of 42 wt.% or less, viscosity of cement milk of 250 to 500 mPa s, and air amount of 2 to 12 vol.%, preferably water powder ratio of 39 wt.% or less, viscosity of cement milk of 290 to 360 mPa s, and air amount of 5.3 to 9.0 vol.%, and a semiflexible paving formed by the injection material.SELECTED DRAWING: Figure 1
