Section 303 — Road Reconditioning

Description

303.01This work consists of reconditioning ditches, shoulders, roadbeds, aggregate surfaces, and roadways.

Material

303.02Conform to the following Subsection: Water for construction 725.01(c)

Construction Requirements

303.03General. Dispose of waste at designated sites or according to Subsection 204.14.

303.04Ditch Reconditioning. Remove slide material, sediment, vegetation, and other debris from existing ditches and culvert inlets and outlets. Resha pe ditches and culvert inlets and outlets to achieve positive drainage and uniform ditch width, depth, and grade or as shown in the plans.

303.05Shoulder Reconditioning. Remove slide material, vegetation, and other debris from existing shoulders including shoulders in parking areas, turnouts, and other widened areas. Repair soft and unstable areas according to Subsection 204.07 . Reshape sho ulders to the widths and slopes shown in the plans.

303.06Roadbed Reconditioning. Remove organic, deleterious, and material larger than 6 inches from the top 6 inches of subgrade. Repair soft and unstable areas according to Subsection 204.07. Scarify surface to a 6 -inch depth. Remove irregularities and shape to a uniform surface. Finish earth surfaces to within 0.05 feet and rock surfaces to within 0.10 feet of required line, grade, and cross -section. Compact according to Subsection 204.11.

303.07Aggregate Surface Reconditioning. Repair soft and unstable areas to the full aggregate surface depth and according to Subsection 204.07. Scarify to the depth of aggregate surfacing shown in the plans. If no depth is indicated in the plans, scarify to a 6- inch depth. Remove irregularities and shape to a uniform surface. Compact and finish the surface according to Subsections 301.05 and 301.06.

303.08Roadway Reconditioning. Perform applicable work described in Subsections 303.03 through 303.07. Maintain existin g cross slope and crown or shape and grade as shown in the plans.
