Abstract

Method of preparing a road surfacing material comprising gravel, pebbles and a dry mineral flour or filler coated with a soft organic binder such as asphalt, bitumen or pitch, wherein the filter is a hydrated mineral, which when heat treated at 200-800 degrees C undergoes an irreversible change to become porous and high absorbant to binder. The addition provides improved wear-resistance. The mineral is pref. an artificial or natural mixt. of 50 wt.% hydrated minerals comprising a hydrates silicate and an anhydrous silicate such as felspar, mica, amphibole, etc.
