Three methods to process Trinidad natural asphalt

摘要

The world's natural asphalts are thermoplastic and coalescent in nature. After removing its water content, the resulting refined asphalts flow, coalesce, its mineral matters sediment when used in blends, and therefore could only be used with specialized road-paving equipment. Three methods are presented here to solve these problems. Method One gives a new way of packaging the natural and refined asphalts in pellet-form. Method Two uses water surface to stop the pellets of natural or refined asphalts from coalescing. Method Three uses water to blend the natural or refined asphalts, producing powders and pellets which do not flow or coalesce. In all methods, the processed asphalts are packaged for use on conventional road-paving equipment, without loss in performance when compared with the refined asphalts.
