Title:
METHOD FOR CONSTRUCTING CONTINUOUSLY REINFORCED CONCRETE PAVEMENT USING FOAM SHOTCRETE
Document Type and Number:
WIPO Patent Application WO/2015/111860
Kind Code:
A1
Abstract:
The present invention relates to a method for constructing a continuously reinforced concrete pavement using foam shotcrete by: positioning continuous reinforcement bars on a base layer where a concrete pavement is constructed; producing normal concrete having a compressive strength of 21-30 Mpa from a batch plant and transporting same to a construction site; and shotting a normal strength concrete, which has been produced by mixing, with a mixing part, fly ash or fine slag powder or a low-grade mixed material produced by mixing the fly and the fine slag powder in a state in which fluidity has been increased by mixing in 20-40% of air bubbles with respect to volume, or shotting a high-performance concrete, which has been produced by mixing, with the mixing part, one or a mixture of two or more of silica fume, meta-kaolin, latex, polymers, and a coloring material, thereby securing high strength and high durability to facilitate maintenance, and rendering a slip form paver to be lightweight by not requiring solidification of the normal strength concrete and the high-performance concrete which are being shot, thus providing ease in construction.
