18 x 18 concrete patio pavers at soil retention

DRIVABLE GRASS®is a 18 x 18 concrete patio pavers permeable, flexible and plantable concrete pavement system manufactured from 18 x 18 concrete patio pavers poly-reinforced concrete. It is designed for use in areas where a permeable, 18 x 18 concrete patio pavers vegetated vehicle access or parking surface is required. Example applications include; emergency and service vehicle access lanes, overflow parking 18 x 18 concrete patio pavers areas, golf cart paths, patios, RV parking areas and 18 x 18 concrete patio pavers.

The concrete paving mat is designed to flex and conform to irregular ground surface contours along pre-defined linear grooves without 18 x 18 concrete patio pavers falling apart. Pre-manufactured holes and cracks allow for root penetration through the mat into subgrade soil, anchoring it firmly into place.  18 x 18 concrete patio pavers The mat’s porous nature enables moisture to filter into the underlying soil, increasing on- 18 x 18 concrete patio pavers site storm water storage and minimizing off-site 18 x 18 concrete patio pavers water flow.  Even when saturated, DRIVABLE GRASS® maintains its load support characteristics and drivable, grassy, surface while minimizing wheel 18 x 18 concrete patio pavers rutting.

The test site was constructed on October 1, 2004.  Prior to grading the site for the test section, the 18 x 18 concrete patio pavers area was proof-rolled with a loaded water truck.  Construction of the test section was conducted by Soil Retention crews and was done under the direction of Dean Sandri, PE.  The “pavement section” consisted of the Drivable Grass (1.5 inch thickness) “wearing surface” underlain by a one-half to one inch thickness of sand leveling bed and a variable thickness of crushed miscellaneous base (CMB); all of which was placed directly on top of the existing sub-grade soils (See Figure 1).  A geotextile separator (Mirafi 140N) 18 x 18 concrete patio pavers was placed between the subgrade and aggregate base to ensure that mixing of the 18 x 18 concrete patio pavers two would be minimized.  18 x 18 concrete patio pavers A rigid concrete apron was provided at each end of the test 18 x 18 concrete patio pavers section to transition vehicular traffic on and off of the pavement.  Below is a cross section of the test area 18 x 18 concrete patio pavers 18 x 18 concrete patio pavers.
