Abstract

The present study is an exploratory research concerned with evaluation of three types of high performance concrete for bridge deck applications. These include A-Type (silica fume 6%), B-Type (silica fume 6% plus fly ash 20%), C-Type (silica fume 6% plus blast-furnace slag 40%). Test results compare with Latex modified concrete (LMC) and Ordinary portland cement concrete (OPC). The results indicates that high performance concrete for bridge deck overlay shows the excellent mechanical and durability performance for LMC and OPC in case of static loading test. Analytical results are similar with experimental results. However there are relative errors of $1{\sim}4mm$ for deflection and maximum 12% for strain.
