INJECTION TYPE RAPIDLY HARDENING METHOD TO PAVE ROAD USING RECYCLED AGGREGATES

摘要

PURPOSE: An injection-type paving method having a rapid hardening function using recycled aggregate is provided to improve self-leveling properties by filling pores of an aggregate layer with ultra-rapid hardening mixtures. CONSTITUTION: An injection-type paving method having a rapid hardening function using recycled aggregate is as follows. An aggregate layer is formed on a roadbed using recycled aggregate. Two or more ultra-rapid hardening mixtures selected from an ultra rapid hardening cement composition, a magnesia phosphate cement composition, and a geo-polymer composition are injected into the aggregate layer, and pores on the aggregate layer are filled with the ultra-rapid hardening mixtures.
