Abstract
An economical roadway marking sheeting matrix that includes hydrated alumina as its main inorganic filler is disclosed. Use of hydrated alumina in the roadway marking sheeting matrix results in reduced mixing and production time, reduction of aging time, lower transportation cost due to lower weight, and lower material cost. In a preferred embodiment, hydrated alumina having a particle size of less that one micron and a GE brightness of 94 or more is incorporated as the main filler system in a roadway marking sheeting matrix. The resulting sheeting matrix may then be fabricated into a road marker by bonding to an upper layer which may include glass beads, and to an adhesive layer for attachment to a road surface.
