    Abstract：Slump and slump retention are the key to the production of premixed pervious concrete. In this paper，the factors influencing the slump loss of the premixed pervious concrete are analyzed，the law of slump loss of pervious concrete mixture was studied by using water reducer and the PRC reinforcing agent respectively，the construction technology of premixed production of pervious concrete was explored，and the control requirement was also put forward.
    Key words：pervious concrete，slumps，premixed production
