Reinforced pervious concrete

Abstract

A pavement such as a road, driveway, sidewalk, parking lot or the like, formed with pervious concrete material and one or more basalt reinforcing members embedded in or positioned below the pervious concrete material. The one or more basalt reinforcing members add structural rigidity to the pervious concrete, making the pervious concrete capable or supporting loads as normally experienced on pavements. The one or more basalt reinforcing members may be basalt rebar rods, or basalt rebar rods having a Figure-Eight shape, or a mesh made of basalt strands. In one example, the pavement may also include a layer of filtration fabric positioned below the basalt reinforcing members. Various methods are described for forming pavements, roads, driveways, sidewalks, parking lots or the like. Such a pavement allows water or moisture to pass through the surface of the pavement and be filtered. Such a pavement reduces flooding and the need for complex storm drainage systems adjacent to the pavement.

1 . A pavement, comprising:
 pervious concrete material; and   one or more basalt reinforcing members embedded in the pervious concrete material.   
     
     
         2 . The pavement of  claim 1 , wherein the one or more basalt reinforcing members are basalt rebar rods. 
     
     
         3 . The pavement of  claim 1 , wherein the one or more basalt reinforcing members are basalt rebar rods having a Figure-Eight shape. 
     
     
         4 . The pavement of  claim 1 , wherein the one or more basalt reinforcing members are a mesh made of basalt strands. 
     
     
         5 . The pavement of  claim 1 , further comprising a layer of filtration fabric positioned below the basalt reinforcing members. 
     
     
         6 . The pavement of  claim 1 , further comprising:
 a compacted soil layer;   a layer of filtration fabric positioned above the compacted soil layer; and   a layer of course aggregate material positioned above the layer of filtration fabric.   
     
     
         7 . The pavement of  claim 6 , wherein the one or more basalt reinforcing members are positioned above the layer of course aggregate material. 
     
     
         8 . The pavement of  claim 7 , wherein the pervious concrete material forms the upper surface of the pavement. 
     
     
         9 . The pavement of  claim 1 , wherein the one or more basalt reinforcing members are positioned approximately two inches or more above the bottom of the pervious concrete material. 
     
     
         10 . The pavement of  claim 1 , wherein the pavement is a road. 
     
     
         11 . The pavement of  claim 1 , wherein the pavement is a parking lot. 
     
     
         12 . The pavement of  claim 1 , wherein the pavement is a driveway. 
     
     
         13 . The pavement of  claim 1 , wherein the pavement is a sidewalk. 
     
     
         14 . A method for forming a road, comprising:
 compacting a sub-base layer;   installing a filtration fabric above the sub-base layer;   installing a layer of aggregate material above the filtration fabric;   positioning one or more basalt rebar reinforcement members above the layer of aggregate material; and   pouring a layer of wet pervious concrete material above the one or more basalt rebar reinforcement members.   
     
     
         15 . The method of  claim 14 , further comprising:
 leveling said layer of wet pervious concrete; and   compacting said layer of wet pervious concrete.   
     
     
         16 . The method of  claim 14 , further comprising curing said layer of pervious concrete. 
     
     
         17 . The method of  claim 14 , wherein the operation of positioning one or more basalt rebar reinforcement members further comprises:
 placing the one or more basalt rebar reinforcement members approximately two or more inches above the layer of aggregate material.   
     
     
         18 . The method of  claim 14 , wherein the pouring operation includes pouring a portion of said wet pervious concrete material below the one or more basalt rebar reinforcement members, so that the wet pervious concrete material embeds the one or more basalt rebar reinforcement members.
