bluestone paving stones at soil retention

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

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

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