q. Resin modified pavement (RMP). RMP is a composite pavement surfacing that uses a unique
combination of hot-mix asphalt and portland cement concrete (PCC) materials in the same layer. The
RMP material is generally described as an open-graded asphalt concrete mixture containing 25 to
35 percent voids which are filled with a resin modified portland cement grout. An RMP layer is typically
5 centimeters (2-inches) thick and has a surface appearance similar to a rough-textured portland cement
concrete.
r. Stone matrix asphalt (SMA). SMA, which is also referred to as stone mastic asphalt, is a mixture
of aggregate, mineral filler, asphalt cement, and a cellulose fiber or a modified asphalt with or without the
fiber. SMA is designed to prevent rutting and abrasion under high loads and/or high tire pressures.
s. Mastic asphalt. Mastic asphalt is a hot-mix asphalt mixture of fine aggregate and asphalt cement
forming a mixture free of voids.
