PROBLEM TO BE SOLVED: To provide a cement injection material in which high fluidity can be maintained for a long time, and of a low material separation property, and a semi-flexure paving structural body of excellent durability and low cost using the injection material by preventing deterioration of fluidity of the injection material, and preventing deterioration of strength achievement performance while maintaining low material separation property. ;SOLUTION: A semi-flexure paving structural body is obtained by injecting cement injection material including cement fine powder of 8μm or less on a base comprising asphalt and aggregates. The cement injection material comprises cement in which cement fine powder including grain of 8μm or less at a volume ratio of 70% or more is blended by 10wt.% or more.;COPYRIGHT: (C)1997,JPO
