Abstract

A study was conducted to show the potential of radio wave reflecting concrete for lateral guidance in automatic highway technology. It contains 0.1 μm-diameter carbon filaments as an admixture. The radiation absorbed is negligible compared to that reflected. The reflectivity at 1 GHz is 10 dB higher for radio wave reflecting cement paste containing 0.5 vol% filaments compared to conventional cement paste. With the filaments, the reflectivity is 29 dB higher than the transmissivity. Without the filaments, the reflectivity is 3-11 dB lower than the transmissivity.
