  • Description:
    The Louisiana Department of Highways has conducted 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. 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" holo (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 pervious, rough, flexible concrete revetment with approximately 30 per cent of the surface area consisting of 2 and 2 1/2 inch cells is formed.

    similar test areas selected for this study 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.
