The invention discloses an indoor testing and measuring device for the blockage recovery capacity of a modified permeable pavement, and relates to the technical field of permeable pavement durability detection. The device is mainly composed of a water injection cavity, a water storage cavity, a water circulation system and a measuring system. The water storage cavity is divided into two semi-cylindrical cavities by a partition plate, and the two semi-cylindrical cavities are respectively communicated with the water injection cavity, the pressure measuring pipe, the water outlet pipe and the water drainage pipe to form two sets of water permeable systems; the two sets of water permeable systems are respectively provided with a modified water permeable pavement sample and a common water permeable pavement sample, and through pre-blocking, water circulation and water outlet speed control, the reading of the pressure measuring pipe can intuitively reflect the change rule of the effective water permeable pore bloc
