A bond breaker is required between portland cement concrete base and portland cement concrete pavement. A bond breaker shall consist of a double application of curing compound or 2 layers of polyethylene sheeting. A 3 inch scored joint will be made to control cracking in the concrete base. The scored joints should be placed at the required surface joint locations. No load transfers will be required in the base slab. Drainage of all existing and constructed pavement structures shall be maintained at all times during construction at no additional cost to the Department. When base course is permeable, provide a base drain outlet consisting of non-plastic embankment (stone) and geotextile fabric, or as specified in the plans, in accordance with 203.09. Submit a dust control plan to address weather, sight clearance, operational procedures, traffic control, and any other project specific concerns. Failure to maintain sight clearance will result in the engineer stopping contractor operations. The Department will identify dust sensitive areas in the plans. In these specific areas, the dust control plan must also include environmental requirements. In order to meet air quality standards, the contractor may be required to use central plant mixing of cement treated mixtures in dust sensitive areas at no direct pay. The contractor may use other types of Class II base course in dust sensitive areas at no direct pay. Furnish and construct surfacing for maintenance of traffic on driveways, pipe crossings, shortterm traffic on raw embankment, slope corrections, or other disturbed roadway sections as directed and in accordance with the following requirements. Construct, install, and adjust manholes, junction boxes, catch basins, culvert end treatments, and safety ends in accordance with these specifications and in conformity with lines and grades shown on the plans or established. Furnish and construct portland cement concrete walks, curb ramps, drives and incidental paving slabs in accordance with these specifications and in conformity with lines, grades, and dimensions shown on the plans or established. Furnish and place reflective pavement markings of hot applied thermoplastic or preformed (cold or hot applied) plastic at the locations shown on the plans. Plastic pavement markings include stripes, gore markings, lines, legends, and symbols. Furnish and apply reflective white or yellow paint for pavement striping, legends, symbols, curbs, and islands in accordance with plan details, the MUTCD, and these specifications.

This work consists of furnishing properly distributed asphalt material followed by a uniform application of aggregate for building a riding surface, improving the surface friction of a roadway, sealing cracks in the roadway, reducing the rate of oxidation of a surface mixture, or as an interlayer to delay or reduce the occurrence of reflective cracking. Asphalt Surface Treatment (AST), sometimes referred to as "chip seal," consists of a specified emulsion applied "cold" or polymer modified asphalt material applied "hot," at the temperature range specified in Table 507-1 for cold applications or Table 507-2 for hot applications, respectively. The application rates of asphalt material and aggregates will vary with aggregate size and existing roadway conditions but, for bid purposes only, shall meet the requirements of Table 507-1 or Table 507-2. The Project Engineer will review the actual application rates.
