Abstract

BLMC-VE (Very-Early Strength latex modified concrete using modified emulsified asphalt) enables early traffic opening in 4 hours after completion of concrete laying, and has excellent adhesion strength, chloride ion penetration resistance, freeze-thaw resistance, crack resistance, durability. Using its characteristics, it is used for overlaying bridge decks or concrete road pavement repair work. By completely removing the old bridge deck concrete and then paving the bridge surface, the load capacity is improved and the effect of structural repair and reinforcement is excellent. As a result of performance evaluation, BLMC-VE can prevent road icing at sub-zero temperatures and promote thawing at melting temperatures.
