1. A flexible sled for applying a liquid emulsion onto a pavement surface comprising:

  • a) a rigid frame assembly adapted to be towed along a pavement surface in a first direction of travel;

    b) said frame assembly having a plurality of elongated members forming an emulsion receiving area bounded by said elongated members;

    c) said elongated members including a pair of side members extending parallel to said first direction of travel and forming a first side member and a second side member;

    d) each of said first and second side members having end blades connected thereto for contacting the pavement surface and for supporting a respective side member; and

    ,e) said end blades being formed of brushesf) a front frame member extending between and connecting said first and second side members;

    g) a middle frame member spaced from said front frame member and extending between said first and second side members; and

    h) a rear flexible frame member spaced from both said front and said middle frame member;

    with a spring steel center section to allow the frame to follow the contour of the pavement surface; and

    ,i) said front frame member includes a squeegee extending downwardly therefrom for preventing said liquid emulsion from flowing under said front frame member and said middle frame member and rear frame member each having a squeegee extending downwardly therefrom for applying said emulsion to the pavement surface when said sled is in motion.
