3.13.5.6 Joint adhesive (Bridge Base) shall be applied to curbs, concrete armoring, and pavement matches so that the entire
joint is covered with a minimum 1/8” thick layer of material.
3.13.6 A tapered overlapping (“ wedge” ) joint may be used on all longitudinal joints provided that the adjacent lane can be
placed when the existing surface temperature is above 50° F.
3.13.6.1 An inclined face (3:1) on the joint shall be formed in the first bituminous mat placed. The inclined face may be for
the entire height or an inclined face with a 1/2” maximum vertical face at the top of the mat.
3.13.6.2 After the initial mat is placed, the mat shall be rolled to the edge of the unconfined face.
3.13.6.3 When the adjoining mat is placed the initial longitudinal wedge shall be treated as in 3.13.5.

3.13.7 The Contractor shall furnish and have available a 10 ft, light-weight metal straightedge with a rectangular cross-
section of 2 by 4” at the paver at all times during paving operations. All courses shall be tested with the straightedge laid across
the transverse joint parallel to the centerline and any variations from a true profile exceeding 3/16” shall be satisfactorily
eliminated. The finished surface of the pavement shall be uniform in appearance, shall be free from irregularities in contour, and
shall present a smooth-riding surface.
3.13.8 Echelon Paving. Echelon paving, when specified or approved, shall be defined as multiple pavers paving
