brick pavers vs concrete at soil retention

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

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

The test site was constructed on October 1, 2004.  Prior to grading the site for the test section, the brick pavers vs concrete 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) brick pavers vs concrete was placed between the subgrade and aggregate base to ensure that mixing of the brick pavers vs concrete two would be minimized.  brick pavers vs concrete A rigid concrete apron was provided at each end of the test brick pavers vs concrete section to transition vehicular traffic on and off of the pavement.  Below is a cross section of the test area brick pavers vs concrete brick pavers vs concrete.
