The invention relates to the technical field of asphalt mixture pavement design, in particular to a design method of an integral pouring type flowing mucilage asphalt mixture pavement. Comprising the following steps that (1) materials are prepared, aggregate comprises diabase with the particle size being 4.75 mm-13.2 mm, limestone mineral powder with the particle size being 0.075 mm or below is adopted as mineral powder, and high-viscosity asphalt is adopted as asphalt; (2) mixing proportion calculation; and (3) preparing and forming a mixture. By means of the design method, the composite structure FMA pavement which can be adjusted based on the filling degree and is integrally poured and formed at a time can be prepared. On the premise of large-flowability mucilage, aggregate gaps can be fully filled with the mucilage, so that asphalt pavements with different mucilage filling degrees can be obtained. Therefore, the waterproof layer on the lower portion of the FMA and the drainage pavement on the upper portio
