Aggregate Base Course Specification

Aggregate Base Course Specification - The document outlines the dpwh standard specifications for various aggregate and stabilized base course materials used in road construction. Preparation of sub grade is specified in contract specifications section 31 00 00, earthwork. Base course and specification and construction and method. It defines two classes of aggregate bases, class 1 and class 2, and specifies the material requirements and testing standards for each. Aggregate subbase for pavements and foundations is specified in contract specifications section 32 11 17, aggregate subbase courses. Coarse aggregate type a or b with a gradation of abc conforming to section 801 of scdot standard specifications. The designated size must conform to the following requirements. When this guide specification is used for aggregate base course under rigid pavement, edit section title of the project specification to: It describes the materials, including crushed stone, gravel, and sand, that make up the aggregate base course. The class of aggregate base shall be as indicated.

When properly processed, hauled, spread, and compacted on a prepared grade to appropriate density standards, reclaimed concrete aggregate used alone or blended with natural or crushed aggregate can be expected to provide adequate stability and load support for use as road or highway base courses. The class of aggregate base shall be as indicated. The class of aggregate base shall be as indicated. Aggregate bases are designated as class 1 or class 2. This work shall consist of furnishing and placing aggregate base course on a prepared surface in accordance with these specifications and in conformity with the lines, grades and thicknesses as established by the engineer. Construct base course in layers not less than 3 inches (75 mm) nor more than 6 inches (150 mm) compacted thickness. Sand gradation 1s or 2s conforming to section 801 of scdot standard The class of aggregate base shall be as indicated. Aggregate bases are designated as class 2 or class 3. Furnish each aggregate material from single source throughout the work.
