sound like the opposite of pervious concrete...with pervious you take out the fine agg. just when you thought that concrete couldn't be any more innovative, they are always working on these things and looking for ways to improve our roadways. michigan needs to take a look at some of the back roads and how to maintain them better and lay off the highways a little bit though.

WE ACTUALLY DID A PIECE OF THE GROVE ROAD BRIDGE DECK WITH THIS STUFF.
JAPAN ENGINEERS CREATED IT FIRST AND U OF M ENGINEERS TOOK IT TO THE NEXT LEVEL WITH THE HELP OF EUCLID CHEMICAL CO.
THE FIBER THAT WENT INTO THESE LOADS IS ABOUT THREE TIMES AS THICK AND THREE TO FOUR INCHES LONG. THE LOADING PROCEDURE WAS THREE DROPS OF MATERIAL AND MIX FOR FIVE MINUTES IN BETWEEN EACH DROP.
THERE WERE ABOUT THREE DOZEN ENGINEERS ON SITE THAT DAY, ABOUT A DOZEN FROM JAPAN, A DOZEN FROM MDOT, AND A DOZEN FROM U OF M.
WE DUMPED IT OUT AT ABOUT AN 8 INCH SLUMP ON THE METER AND AN ACTUAL 6 INCH ON THE BRIDGE. COMES OUT LIKE A GRAY HAIRY GOO.
FROM WHAT I WAS TOLD, MDOT AND U OF M ARE CHECKING THIS SECTION EVERY THREE MONTHS FOR THE NEXT TEN YEARS. THEY WANT TO SEE THE EFFECTS OF FREEZE AND THAW ON IT.
