摘要
The eruption of Mount Pinatubo in the Philippines in 1991 deposited 1.5 billion in 3 of volcanic ash on the surrounding land. The material is accessible and its substitution for other materials ought to provide large cost savings if suitable techniques for using it in civil engineering can be developed. This paper describes the use of the ash as a replacement for conventional fine aggregate in bituminous mixes for road surfacings. A full-scale trial was constructed using hot rolled asphalt and asphalt concrete surfacings containing 53% ash and 17.5% ash respectively. Performance to date has been satisfactory. In the laboratory, performance testing of the trial surfacings using wheel track testing has demonstrated their high resistance to deformation and confirmed the potential suitability of a hot rolled asphalt mix as an effective alternative to the widely-used asphalt concrete. Conclusions are drawn for using volcanic ash in road building.
