HIGH ELASTIC MMA RESIN AND ULTRA THIN NOISE REDUCING PAVEMENT STRUCTURE FOR BRIDGE DECK USING THE SAME

摘要

PURPOSE: An ultra thin noise reducing pavement structure for bridge deck is provided to increase span length of a bridge, to reduce whole construction cost of the bridge, and to ensure water resistance without separate waterproof layer. CONSTITUTION: A highly elastic methyl methacrylate resin for paving a bridge deck comprises methyl methacrylate 40~70 weight%, polymethyl methacrylate 5~30 weight%, butyl acrylate 5~30 weight% and urethane 5~30 weight%. An ultra thin noise reducing pavement structure for bridge deck comprises: an adhesive layer(2) formed on a bridge deck(1) by the highly elastic methyl methacrylate resin; a lower layer(3) formed on the adhesive layer by highly elastic methyl methacrylate resin or highly elastic methyl methacrylate resin concrete; and a top layer(4).
