A VERY EARLY STRENGTH CONCRETE COMPOSITIONS USING MODIFIED EMULSIFIED ASPHALT AND METHOD OF BRIDGE DECK PAVEMENT USING THE SAME

摘要

The present invention relates to an ultra-rapidly hardening concrete composition using modified emulsified asphalt and a bridge deck pavement technique using the same and, more particularly, to an ultra-rapidly hardening concrete composition using modified emulsified asphalt and a bridge deck pavement technique using the same, wherein a re-emulsification type power resin is added to ultra-rapidly hardening cement to ensure durability and flexural tensile strength and a synthetic polymer is added to emulsified asphalt so that cement mixing properties, tensile strength, adhesiveness, durability and operability are improved. The ultra-rapidly hardening concrete composition using the modified emulsified asphalt according to the present invention contains 16 to 26 wt% of ultra-rapidly hardening cement binding material; 26 to 56 wt% of fine aggregate; 25 to 55 wt% of thick aggregate; 1 to 5 wt% of re-emulsification type powder resin; 1 to 10 wt% of water; and 1 to 30 wt% of modified emulsified asphalt.
