Abstract
A pre-packaged bituminous sandstone material, which can be applied to damaged pavement areas at ambient temperatures, is prepared by comminuting bituminous sandstone in the presence of water to form an intimate mixture of bituminous sandstone having particles which pass through a one-quarter inch minus screen, preferably through a one-eighth inch minus screen with sufficient water, to form a material having a water content of from about 3% to about 20%, based on the weight of the mixture. The mixture is then packaged in a vapor-proof container, to maintain its water content. Damaged pavement is subsequently repaired simply by removing the mixture from the container and applying the material, at ambient temperatures, to the damaged areas.
