Calcium carbonate (CaC03) is one of the most widely used mineral filler pigments in traffic marking paints. Calcium carbon ate is a soft, chalklike material, and fly ash is a much harder material. In theory by replacing part of the calcium carbonate with fly ash in traffic paint the paint would be more durable.

The calcium, carbon and oxygen atoms can arrange themselves in three different ways, to form three different calcium carbonate minerals. Precipitated calcium carbonate (PCC), a manufactured form of calcium carbonate, is made by first hydrating high-calcium quicklime, and then reacting the resulting slurry or milk oflime with carbon dioxide.

On the one hand, calcium carbonate crystals attach to the surface of sand particles, making the sand particles become rough, so the friction angle significantly increases. On the other hand, calcium carbonate growth among sand particles plays a bridging role, which is able to significantly improve the strength of the specimen [69].
