This study was performed to evaluate the engineering properties of permeable polymer concrete with Fly Ash and $CaCo_3$. The following conclusions were drawn; 1. The unit weight was in the range of $1,830{\sim}1,932kgf/m^3$, the unit weights of those concrete were decreased 16~20% than that of the normal cement concrete. 2. The highest strength was achieved by fly ash 50% and $CaCo_3$ 50% filled permeable polymer concrete, it was increased 26% by compressive strength, 121% by tensile strength and 275% by bending strength than that of the normal cement concrete, respectively. 3. The ultrasonic pulse velocity was in the range of 2,805~2,904m/s, which was showed about the same compared to that of the normal cement concrete. Fly ash 50% and $CaCo_3$ 50% filled permeable polymer concrete was showed higher pulse velocity.
