619.1 Description. This work shall consist of the elimination of pavement edge differential.
619.2 Material. Wedge slopes shall be constructed of an approved material or an approved preformed unit.
Acceptance of wedge slope material will be based on visual examination.
619.3 Construction Requirements. At the contractor's option, elimination of pavement edge differential may
be accomplished by either conducting operations in such a manner that traffic is exposed to no more than a two- inch differential, by constructing a wedge shaped slope adjacent to the pavement edge or by furnishing and installing temporary concrete traffic barrier in accordance with Sec 617.
619.3.1 Wedge slopes shall be constructed as shown on the plans or as directed by the engineer. Slope material,
other than preformed units, shall be compacted to the satisfaction of the engineer.
619.3.2 Wedge slope material shall be removed and the pavement edge returned to a vertical face prior to
placement of adjacent shoulder or pavement material. Material used to construct wedge slope shall be disposed of as approved by the engineer.
619.3.3 Temporary concrete traffic barrier shall be installed as shown on the plans or as directed by the engineer.
619.4 Method of Measurement. Final measurement will not be made except for authorized changes during
construction or when appreciable errors are found in the contract quantities. Where required, measurement will be made to the nearest linear foot along each edge of pavement for all locations actually treated. No location will be measured more than once, regardless of the number of applications. The revision or correction will be computed and added to or deducted from the contract quantity.
619.5 Basis of Payment. The accepted quantity of pavement edge treatment will be paid for at the contract unit
price for the units constructed. Payment will be considered full compensation for all labor, equipment and material to construct, maintain, replace, remove and dispose of pavement edge treatment. No direct payment will be made for more than one application at any location.
