610.02 Materials
Provide ma terials in accordance with the following subsections: Material: Subsection: Asphalt Mixture 708.04 Portland Cement Concrete Class A 701.01 Tactile Warning Device Material 733.1
610.03 Equipment — Vacant
610.04 Construction Methods
A.Concrete Construction Form, place, and finish concrete in accordance with Subsection 414.04, “Construction Methods," except, broom -finish or burlap -drag the final surface of concrete sidewalks, driveways, and divider strips, or complete as d irected by the Resident Engineer. Connect the old and new pavement with a sawed joint. Use a hand operated or power compactor to compact uniformly the subgrade material. The type and weight of the compactor must meet the Resident Engineer’s approval. Ha nd-tamp areas inaccessible to the compactor.
610.04 Concrete Or Asphalt Sidewalks, Driveways, Dividing Strips, and Tactile Warning
546 (1) Expansion Joints Construct expansion joints to the dimensions required by the Contract and fill with the pre-molded filler as shown on the Plans.
2.Dummy Joints Use a jointing tool, or other method approve d by the Resident Engineer, to divide the sidewalk into sections with dummy joints. Extend the dummy joints into the concrete at least one -third the concrete slab depth and to ⅛ in [3 mm] wide.
3.Construction Joints Form construction joints around appur tenances, extending the joints into the sidewalk, driveway, or dividing strip. Install pre -molded expansion joint filler to a thickness of ¼ in [6 mm], between the concrete and fixed structures.
4.Curing Use moist burlap or cotton mats to cure concrete for at least 72 hr in accordance with Subsection 414.04.J, “Curing. ” During the curing period, do not allow traffic to use the surface. Prevent vehicular traffic from using the surface for additional time as directe d by the Resident Engineer.
B.Asphalt Construction Excavate and build forms in accordance with Subsection 609.04.A, “Excavation, ” and Subsection 609.04.B, “Forms.” Perform asphalt construction in accordance with Subsection 411.04, “Construction Methods.” Place the asphalt material on the compacted subgrade in one or more layers, and compact to the thickness shown on the Plans. Use a hand -operated or power roller to compact uniformly the material. The type and weight of the roller must meet the Resident Engineer’s approval. Hand -tamp areas inaccessible to the roller.
C.Backfill Backfill the sides of sidewalks and driveways imm ediately after form removal and honeycombed areas are filled and pointed. Backfill using material, approved by the Resident Engineer, thoroughly compacted in layers no deeper than 6 in [150 mm] compacted. Protect the concrete or asphalt material from dam age during placement and compaction. Ensure the width of the backfill is at least 2 ft [0.6 m] where the elevation of the adjacent surface is lower than the sidewalk or driveway.
D.Protection from Traffic Use barricades to protect sidewalks, driveways, an d dividing strips from traffic. Protect concrete for 7 days and asphalt for 1 day, unless otherwise directed by the Resident Engineer.
E.Remove, Relay, or Extend Brick or Stone Sidewalks Prepare the subgrade in accordance with Subsection 610.04.A, "Concrete Construction" when relaying or extending brick or stone sidewalks. Provide a sand cushion 1½ in [38 mm] deep with a CONCRETE OR ASPHALT SIDEWALKS, DRIVEWAYS, DIVIDING STRIPS, AND TACTILE WARNING 610.06 547 uniform, flat surface at the subgrade elevation. Before relaying sidewalk, clean the old bricks . Lay the bricks or stones close together to match the existing walk, and tamp firmly into the sand cushion. Ensure the surface of the walk is smooth and at the grade shown on the Plans. Fill the joints with mortar grout composed of one part portland cem ent and two parts mortar sand by volume, by spreading an excess over the surface and sweeping into the joints. Clean the surface of the brick. Backfill the sides of the walk as required in the Contract for concrete sidewalks.
F.Tactile Warning Device Install tactile warning device materials in accordance with the manufacturer’s specifications and as shown on the Plans.

611.02 Manholes , Drop Or Curb Inlets, and Junction Boxes
548 SECTION 611 MANHOLES, DROP OR CURB INLETS, AND JUNCTION BOXES
611.01 Description
This work consists of constructing manholes, drop or curb inlets, junction boxes, or similar structures using precast concrete units, brick masonry, or cast -in-place concrete.
611.02 Materials
A.General Provide materials in accordance with the following section and subsections : Material: Section or Subsection: Portland Cement 701.02 Mortar Sand 701.05 Clay Brick 714.01 Concrete Brick 714.02 Structural Steel 724 Steel Castings 725.02 Iron Castings 725.03 Precast Manholes 726.01 Portland Cement Concrete Class A 701.01 The Department will allow precast concrete u nits instead of brick masonry or cast -in-place concrete unless otherwise shown on the Plans, except, the Department will not allow brick masonry for the construction or rebuilding of sanitary sewer manholes. Provide two T-handles for up to the first 20 locking manhole covers and one for each additional 20 locking manhole covers.
B.Portland Cement Mortar With brick masonry, provide mortar composed of one part portland cement and two parts mortar sand by volume, mixed with water to form a plastic consistency .
