NOVELTY - An asphalt plant (11) consists of an adjacent wood-tar manufacturing apparatus (1). The wood-tar manufacturing apparatus consists of a gasifier (5) for thermally decomposing biomass and producing pyrolysis gas and carbonized material, a heat exchanger (6), and a secondary combustion chamber (9). A sand dryer (12) is provided downstream from the secondary combustion chamber of the wood-tar manufacturing apparatus for heat-drying sand used as raw material of asphalt mixture.    USE - Asphalt plant with adjacent wood-tar manufacturing apparatus is used for manufacturing asphalt mixture.    ADVANTAGE - The asphalt plant effectively uses wood tar obtained as by-product by thermal decomposition of wood-type biomass, such as scrap wood and coppiced timber. The use of fuel for burner of aggregate is reduced, which contributes to energy-saving of asphalt plant. Emission of carbon dioxide is suppressed.    DETAILED DESCRIPTION - An asphalt plant consists of an adjacent wood-tar manufacturing apparatus. The wood-tar manufacturing apparatus consists of a gasifier for thermally decomposing biomass and producing pyrolysis gas and carbonized material, a heat exchanger for cooling the generated hot pyrolysis gas to a temperature at which wood tar in pyrolysis gas condenses, and a secondary combustion chamber for burning the amount of gas remaining in the pyrolysis gas derived from the heat exchanger and not condensed. A sand dryer is provided downstream from the secondary combustion chamber of the wood-tar manufacturing apparatus for heat-drying sand used as raw material of asphalt mixture. Sand is heat-dried to preset temperature by the high-temperature waste gas derived from the secondary combustion chamber.
