The invention relates to a bituminous mixture for a high-environment-protection road and a construction method of the bituminous mixture. The bituminous mixture is prepared from the following raw materials in parts by weight: 75 to 79 parts of aggregates, 7 to 9 parts of bitumen, 4 to 6 parts of bitumen modifier, 6 to 8 parts of anti-aging agent, 4 to 6 parts of mineral powder, 3 to 7 parts of combination fibers, 0.5 to 0.9 part of stabilizer and 0.5 to 0.9 part of auxiliaries. A large-scale application direction for coal gangue, cast waste sand, nickel slag and waste polyvinyl chloride plastic bottles is found out, wastes are turned into wealth, environmental pollution and land occupation of solidified wastes are reduced, resources are further utilized, and the bituminous mixture is energy-saving and environmentally friendly. A road surface paved by the bituminous mixture is good in ageing-resistant performance, good in weather fastness, good in wear resistance, good in heat resistance, not easy to fatigue or crack and good in rutting resistance, the production cost of the bituminous mixture is low, and the aggregates cannot be scattered easily in a production process.
