Methods for producing precast pervious concrete panels
Methods directed to a producing precast pervious concrete panels. Each pervious concrete panel has a plurality of layers of concrete mixture, wherein the aggregate used in each layer may be a different size and each layer is compacted after being laid. The method may further include providing a slip-former machine or an extruder machine to lay the layers of pervious concrete mixture.
1. A method for producing a pervious concrete panel having a plurality of pervious concrete layers, the method comprising the steps of:
providing a first pervious concrete mixture comprising a first aggregate having a first maximum aggregate diameter;
providing a second pervious concrete mixture comprising a second aggregate having a second maximum aggregate diameter;
wherein the first maximum aggregate diameter is different than a second maximum aggregate diameter;
laying the second pervious concrete mixture and compacting the second pervious concrete mixture to a second depth; and
laying the first pervious concrete mixture on top of the second pervious concrete mixture and compacting the first pervious concrete mixture to a first depth.
2. The method of claim 1 , further comprising the steps of:
providing a third pervious concrete mixture comprising a third aggregate having a third maximum aggregate diameter;
wherein the third maximum aggregate diameter is different than the first and second maximum aggregate diameters; and
laying the third pervious concrete mixture and compacting the third pervious concrete mixture to a third depth prior to laying the second pervious concrete mixture, whereby the second pervious concrete mixture is laid on top of the third pervious concrete mixture.
3. A method for producing a pervious concrete panel having a plurality of pervious concrete layers. the method comprising the steps of:
providing a first pervious concrete mixture comprising a first aggregate having a first maximum aggregate diameter;
providing a second pervious concrete mixture comprising a second aggregate having a second maximum aggregate diameter;
wherein the first maximum aggregate diameter is different than the second maximum aggregate diameter;
providing a slip-form machine;
laying the second pervious concrete mixture with the slip-form machine and compacting the second pervious concrete mixture to a second depth; and
laying the First pervious concrete mixture on top of the second pervious concrete mixture with the slip-form machine and compacting the first pervious concrete mixture to a first depth.
4. The method of claim 3 , further comprising the steps of:
providing a third pervious concrete mixture comprising a third aggregate having a third maximum aggregate diameter;
wherein the third maximum aggregate diameter is different than the first and second maximum aggregate diameters; and
laying the third pervious concrete mixture with the slip-form machine and compacting the third pervious concrete mixture to a third depth prior to laying the second pervious concrete :mixture, whereby the second pervious concrete mixture is laid on top of the third pervious concrete mixture.
5. A method for producing a pervious concrete panel having a plurality of pervious concrete lavers, the method comprising the steps of:
providing a first pervious concrete mixture comprising a first aggregate having a first maximum aggregate diameter;
providing a second pervious concrete mixture comprising a second aggregate having a second maximum aggregate diameter;
wherein the first maximum aggregate diameter is different than the second maximum aggregate diameter;
providing an extruder machine;
laying the second pervious concrete mixture with the extruder machine and compacting the second pervious concrete mixture to a second depth; and
laying the first pervious concrete mixture on top of the second pervious concrete mixture with the extruder machine and compacting the first pervious concrete mixture to a first depth.
6. The method of claim 5 , further comprising the steps of:
providing a third pervious concrete mixture comprising a third aggregate haying a third maximum aggregate diameter;
wherein the third maximum aggregate diameter is different than the, first and second maximum aggregate diameters; and
laying the third pervious concrete mixture with the extruder machine and compacting the third pervious concrete mixture to a third depth prior to laying the second pervious concrete mixture, whereby the second pervious concrete mixture is laid on top of the third pervious concrete mixture.
