Section 608 — Paved Waterways

Description

608.01This work consists of constructing paved waterways not contiguous to the traveled way. Paved waterways are designated as follows: Type 1 – Grouted rubble Type 2 – Mortared rubble Type 3 – Concrete and rubble Type 4 – Concrete Type 5 – Asphalt

Material

608.02Conform to the following Subsections: Soil and soil- aggregate materials 704.01 General mortar 701.05(a) Neat hydraulic cement grout 701.04(a) (2) Reinforcing steel 709.01 Rock for masonry structures (rubble) 705.03 Sand 703.14

Construction Requirements

608.03General. Excavate and backfill according to Section 209. Place and compact the bedding material with at least three passes of a lightweight mechanical tamper, roller, or vibratory system. Construct minor concrete according to Section 601. Construct rubble masonry according to Section 620.

608.04Grouted Rubble Paved Waterway (Type 1). Clean and wet the rubble to near saturation. Set rubble in a broken pattern with no continuous joint across the waterway or parallel to the flow line. Place rubble into the mortar bed with the flat faces up and the longest dimension at right angles to the flow line. Make the joints 1 to 2 inches wide. Ram each piece of rubble until it is firm and true to the surface in grade, alignment, and cross -section. Remove and relay rubble having an irregular or uneven surface. Fill the joints with sand to within 4 inches of the surface. Pour and broom grout into the joints until the grout is ½ inch below the surface of the rubble. Clean excess grout from the rubble surface. 608.05 Mortared Rubble Paved Waterway (Type 2). Clean and wet the rubble to near saturation. Set rubble in a broken pattern with no continuous joint across the waterway or parallel to the flow line. Place rubble into the mortar bed with the flat face up and the longest dimension parallel to the flow line. Make joints 1 to 2 inches wide. Ram each piece of rubble until it is firm and true to the surface in grade, alignment, and cross -section. Remove and relay rubble having an irregular or uneven surface. Fill joints to within ½ inch below the surface of the rubble. Clean excess mortar from the rubble surface.

608.06Concrete and Rubble Paved Waterway (Type 3). Perform concrete work according to Section 601. Secure the reinforcing steel within the middle third of the depth of the concrete foundation if shown in the plans. Clean and wet the rubble to near saturation. Embed rubble into the concrete foundation in a broken pattern with no continuous joint across the waterway or parallel to the flow line. Make the joints 1 to 2 inches wide. Fill the joints with mortar to 1 inch below the surface of the rubble. Clean excess mortar from the rubble surface.

608.07Concrete Paved Waterway (Type 4). Perform the work according to Section 601.

608.08Asphalt Paved Waterway (Type 5). Perform the work according to Section 403, Type II. Clean and seal the cracks according to Section 414 before overlaying existing asphalt paved waterway.

608.09Acceptance. See Table 608-1 for sampling, testing, and acceptance requirements. Bedding material and sand will be evaluated under Subsections 106.02 and 106.04. Material for grout and mortar will be evaluated under Subsections 106.02 and 106.03. Mortar placement will be evaluated under Subsections 106.02 and 106.04. Construction of paved waterways will be evaluated under Subsections 106.02 and 106.04. Asphalt concrete will be evaluated under Section 403. Cleaning and sealing cracks will be evaluated under Section 414. Excavation and backfill will be evaluated under Section 209. Minor concrete will be evaluated under Section 601. Rubble masonry will be evaluated under Section 620.

Measurement

608.10Measure the Section 608 pay items listed in the bid schedule according to Subsection 109.02 and the following as applicable: When measuring paved waterways by the square yard, measure the width horizontally to include the total width. Measure the length parallel to the flow line. When measuring paved waterways by the linear foot, measure along the flow line of the paved waterway.

Payment

608.11The accepted quantities will be paid at the contract price per unit of measurement for the Section 608 pay items listed in the bid schedule. Payment will be full compensation for the work prescribed in this Section. See Subsection 109.05 . Table 608-1 Sampling, Testing, and Acceptance Requirements
