The properties such as durability a d mecha ical perfoma ce which refers to the compressive stre guh a d the foldi g stre gth of co crete ca be improved by addi g polypropyle e fiber a d steel fiber i it. I door tests were made to study the mecha ical performa ce a d durability of the slag co crete which add i polypropyle e fiber a d steel fiber. The results show that: whe the volume fractio of the polypropyle e f-i bei is 011 perce t, its mecha ical performa ce is best; whe the volume fractio of the steel slag is 1175 per- ce t, the mechabical performa ce of the co crete is best; the polypropyle e fiber ca effectively improve the durability of co crete. It is proved that the high performa ce paveme t co crete has excelle t mecha ical per- forma ce a d durable performa ce a d bright applicatio prospect a d developi g foregrou d. Ke
