Abstract
A solid state porous rubber overlayment friction course is formed from recycled rubber, plastic and/or other products, and facilitates drainage of standing water from the road surface. The overlayment may have holes running through its surface to expedite water drainage, and also may have grooves on its undersurface.
Claims13
A pavement overlayer construction comprising:
- a plurality of pavement particles, each said pavement particle comprising:
- a rubber core;
- and
- a polymer binding component surrounding at least a portion of said rubber core,
- wherein said pavement particles form a layer having a plurality of voids distributed in said pavement overlayer, and at least some said voids are disposed between adjacent said pavement particles, said pavement particles form an integral, self-supporting sheet, and said integral, self-supporting sheet has a plurality of holes formed therein, said holes running from a top of said sheet to a bottom of said sheet.
An elastomeric overlayer, comprising:
- a plurality of particles, each said particle comprising:
- a rubber core;
- and
- a polymer binding component surrounding at least a portion of said rubber core,
- wherein said particles form a layer having a plurality of voids distributed in said elastic overlayer, and at least some said voids are disposed between adjacent said particles, said particles form an integral, self-supporting sheet, and said integral, self-supporting sheet has a plurality of holes formed therein, said holes running from a top of said sheet to a bottom of said sheet.
A pavement construction, having a layer of porous pavement material having a first surface and a plurality of channels formed beneath said first surface, said pavement material comprising a plurality of pavement particles, wherein said pavement particles form said layer and said layer has a plurality of voids at least some of which are disposed between adjacent said pavement particles, wherein said channels are dimensioned and disposed so that a portion of a second surface underlying said layer is exposed within said channels, and comprising:
- a plurality of overlayment particles, each said overlayment particle comprising;
- a rubber core, and
- a polymer binding component surrounding at least a portion of said rubber core,
- wherein said overlayment particles are formed in an integral, self-supporting sheet which has a plurality of holes formed therein, said holes running from a top of said sheet to a bottom of said sheet, said holes effecting fluid communication with said layer of porous pavement material.
A process for making a pavement overlayer construction, comprising the steps of:
- providing a plurality of pavement particles, each said pavement particle having a rubber core and a polymer binding component surrounding at least a portion of the rubber core;
- forming the pavement particles into a layer having a plurality of voids distributed in the layer, with at least some of the voids disposed between adjacent said pavement particles, by shaping the pavement particles into an integral, self-supporting sheet;
- and
- forming a plurality of holes in the integral, self-supporting sheet, the holes running from a top of the sheet to a bottom of the sheet.
