The issue of the Asphalt Weekly Monitor® used will be for the last full week in the previous month received by the Department prior to the first day of the index month. If the specified publication ceases to be available for any reason, the Department at its discretion will select and begin using a substitute price source or index to establish the Monthly Asphalt Binder Price Index.

412.01 Description

This work consists of cold -milling and removing pavement surfaces to the specified depth, and removing ridges, ruts, and imperfections.

412.02 Materials — Vacant

412.03 Equipment

Provide a milling machine that:  Can plane at least 1½ in [40 mm] deep in a single pass;  Is self -propelled;  Has the power, traction, and stability to maintain accurate depth of cut and slope;  Automatically establishes profile grades along each side of the milling machine by referring to the existing pavement with a ski or matching shoe, or by an independ ent grade control;  Automatically controls cross slope; and  Has an integral loading mechanism to remove the material cut from the pavement surface and discharge it into a truck in one operation.

412.04 Construction Methods

Mill the existing pavement to the line, grade, and cross section shown on the plans, and provide a milled surface that has a uniform texture and a smooth riding surface for traffic. Ensure no deviations are RUMBLE STRIP 413.03 greater than 3/16 in in a 10 ft [5 mm in a 3 m] section. Make corrections as appr oved by the Construction Engineer. Make passes to remove irregularities and to profile the surface to the depth and cross slope shown on the Plans. Prevent traffic hazards. At the end of the daily milling operation, ensure that milled surface is smooth. Immediately apply fog seal to the milled areas, in accordance with Section 407, "Fog Seal and Tack Coat," unless overlaying the milled area with bituminous material on the same day. Dispose of removed materials in accordance w ith Subsection 104.09, “Removal and Disposal of Salvaged Materials, Structures, and Obstructions.”
