Performance of volcanic ash in bituminous mixes.
The eruption of Mount Pinatubo in the Philippines in 1991 resulted in large volcanic deposits known as lahar. This material has the potential for being a source of aggregate used in road construction.
This document reports on investigations into the use of lahar as a fine aggregate in bituminous mixtures.
