USING A HIGH-PERFORMANCE TWO-LAYER CONCRETE PAVEMENT CONCRETE APPARATUS AND METHOD

摘要

The present invention relates to an apparatus and a method for paving two-layer concrete. More specifically, normal concrete generated in one batcher plant forms the bottom layer of two-layer concrete pavement, and the high performance concrete having high strength and high durability wherein bubbles and mixed materials are mixed with the normal concrete is stacked in a thinner thickness than the thickness of the bottom layer to be paved.
