ABSTRACT:
A paving composition comprising asphalt and micro-granular coal which are uniformly combined integrally with each other without thermal decomposition of said coal and a method for producing a paving composition which comprises triturating a mixture of asphalt and coal at a temperature below the thermal decomposition point of the coal thereby to reduce the diameter of the resulting micro-granular coal to 1 to 100.mu. and, at the same time, to achieve the uniform integral combination of asphalt and coal. Thereby, there is provided a paving composition which is excellent in thermal stability, weather resistance, adhesive property, sticking strength, viscoelasticity and workability. Moreover, besides the main components, asphalt and coal, various modifying agents or additives may be further incorporated so that the properties of the paving composition can be further improved.
