Permeable pavement and cured carbon fiber composition and a related method

A method of making a permeable, reinforced pavement composition, the method comprising:

• providing a first quantity of pavement material;
• providing a second quantity of cured carbon fiber composite material (CCFCM) comprising carbon fibers incorporated with a thermoplastic binding polymer;
• separating the second quantity of CCFCM into CCFCM particles comprising a range of CCFCM particle size fractions;
• and
• after separating, adding the separated range of particle size fractions of CCFCM to the pavement material, thereby producing a permeable, reinforced pavement composition having improved characteristics and infiltration performance compared to characteristics and infiltration performance of a pavement material devoid of the second quantity of CCFCM;
• wherein the second quantity of CCFCM particles comprises a selected range of CCFCM particle size fractions such that-the amount of carbon fibers relative to a percentage of the permeable, reinforced pavement composition is chosen so that the permeable, reinforced pavement composition has a desired water infiltration rate of from 200 inches per hour to 3,000 inches per hour, as measured by ASTM test standard C1701 at 7 days;
• wherein a concentration of the second quantity of CCFCM ranges from 0.15 weight percent of CCFCM to 6 weight percent of CCFCM per total weight of the permeable, reinforced pavement composition;
• wherein the second quantity of CCFCM comprises a range of CCFCM particle size fractions selected from the group consisting of:
• CCFCM particles smaller than 3.35 mm, CCFCM particles smaller than 3.35 mm and larger than 2 mm, CCFCM particles smaller than 2 mm and larger than 0.841 mm, and CCFCM particles smaller than 0.841 mm;
• and
• wherein the permeable, reinforced pavement composition comprises a hardened porosity of from 15 weight percent air voids to 35 weight percent air voids per total weight of the permeable, reinforced pavement composition, as measured by ASTM test standard C1754.
