PAVING BLOCK STUDY

FIELD TESTS WITH AN EXPERIMENTAL REVETMENT CONSISTING OF CELLULAR CONCRETE REVETMENT BLOCKS USED IN CONJUNCTION WITH PLASTIC FILTER CLOTH AND/OR VEGETATION SUCH AS GRASS OR VINES WERE CONDUCTED. THE PRECAST BLOCKS ARE OF VIBRATED CONCRETE, WEIGH 13 LBS., AND ARE APPROXIMATELY 8" SQUARE BY 4" DEEP. EACH BLOCK HAS A 2-1/2" HOLE (CELL) THROUGH THE CENTER WITH NOTCHES ON FOUR SIDES WHICH MATCH THOSE OF ADJACENT BLOCKS TO FORM ADDITIONAL CELLS. WHEN THEY ARE LAID SIDE BY SIDE, A PREVIOUS, ROUGH, FLEXIBLE CONCRETE REVETMENT WITH APPROXIMATELY 30 PERCENT OF THE SURFACE AREA CONSISTING OF 2 AND 2-1/2 INCH CELLS IS FORMED. THIS CONCEPT WAS DEVELOPED IN THE NETHERLANDS AND HAS BEEN USED EXTENSIVELY IN THAT COUNTRY FOR A VARIETY OF PURPOSES SUCH AS STABILIZATION OF HIGHWAY SHOULDERS, PARKING AREAS, PARK ROADS, CANAL SECTIONS, BRIDGE AND OVERPASS EMBANKMENTS, AND BACKSLOPES OF DIKES ALONG THE NORTH SEA. SIMILAR TEST AREAS SELECTED INCLUDED SHOULDERS SUBJECT TO RUTTING FROM OCCASIONAL TRAFFIC, DITCH AND CULVERT OUTLETS, AN OVERPASS EMBANKMENT SUBJECT TO SOIL FAILURE AND EROSION FROM EMBANKMENT SEEPAGE, AND A HIGHWAY EMBANKMENT SUBJECT TO RAPIDLY CHANGING WATER LEVELS AND WAVE ACTION FROM THE GULF OF MEXICO. THESE INSTALLATIONS WERE OBSERVED FOR 12 TO 18 MONTHS AND JUDGED TO BE EQUAL OR BETTER THAN THE REVETMENT SYSTEMS BE- ING USED. THE TEST INSTALLATIONS AND OBSERVATIONS ARE DE- SCRIBED WITH BEFORE AND AFTER PICTURES. /FHWA/
