Engineering Properties of Resin Modified Pavement (RMP) for Mechanistic Design

Resin modified pavement (RMP) is a composite pavement sufiacing that
uses a unique combination of asphalt concrete (AC) and portland cement concrete
(PCC) materials in the same layer. The RMP layer is generally described as an
open-graded asphalt concrete mixture containing 25- to 35-percent air voids which
are filled with a resin modified portland cement grout. The “open-graded asphalt
concrete mixture and resin modified portland cement grout are produced and
placed separately. The RMP is typically a 50-mm-thick layer placed on top of a
flexible pavement substructure when newly-constructed. This same thickness may
be placed on existing flexible or rigid pavement structures as well.
