The invention discloses a design method for resource utilization of construction waste. Four processing and production units of an oil removing and uniformizing module, a rough breaking and rough selecting module, a fine breaking and fine selecting module and a powder grinding activation module are arranged; the oil removing and uniformizing module has the functions of soil removing and uniform feeding; the rough breaking and rough selecting module has the functions of producing four types of recycled aggregate, primary removed iron and light materials; the fine breaking and fine selecting module has the functions of producing two types of recycled aggregate, primary removed iron and light materials; the powder grinding activation module has the functions of producing recycled fine aggregate and micro powder; and each module is provided with a separate dust removal system, and associated parameters of each module and adjacent front and rear modules are dynamically adjustable. Accordingto the modular design method, the production modules, process equipment, auxiliary equipment, transportation equipment and dust removal equipment can be selected, designed and combined can be different according to different construction sites, different construction waste raw materials, and different specifications and yields of the produced recycled aggregate, the construction waste is timely and efficiently disposed, the recycled aggregate is produced, and the recycled aggregate of the different specifications can also be made into road structural layer materials and various wall body materials.
