Aggregate Base Course Specification

Aggregate Base Course Specification - Furnish each aggregate material from single source throughout the work. Perform work in accordance with recommendations in the geotechnical report by arnold consulting engineering services, inc., the kentucky department of highway’s standard specifications for road and bridge construction standards and city of bowling green standards. 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. The document outlines the dpwh standard specifications for various aggregate and stabilized base course materials used in road construction. Coarse aggregate type a or b with a gradation of abc conforming to section 801 of scdot standard specifications. Aggregate bases are designated as class 1 or class 2. 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. Sand gradation 1s or 2s conforming to section 801 of scdot standard Aggregate subbase for pavements and foundations is specified in contract specifications section 32 11 17, aggregate subbase courses.

Perform work in accordance with recommendations in the geotechnical report by arnold consulting engineering services, inc., the kentucky department of highway’s standard specifications for road and bridge construction standards and city of bowling green standards. Construct base course in layers not less than 3 inches (75 mm) nor more than 6 inches (150 mm) compacted thickness. The work provided under this specification shall include the furnishing, placement and compaction of aggregate base course (abc) to the lines, grades, dimensions, moisture, density and typical sections as specified in the plans and specifications, and or as directed by the engineer. 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 1 or class 2. Coarse aggregate type a or b with a gradation of abc conforming to section 801 of scdot standard specifications. Provide crushed material having a minimum compressive strength of 45 psi at 0 psi lateral pressure and 175 psi at 15 psi lateral pressure using triaxial testing procedures. Base course for rigid paving and select the words rigid pavement base course throughout. Aggregate bases are designated as class 1 or class 2.

The Class Of Aggregate Base Shall Be As Indicated.

Preparation of sub grade is specified in contract specifications section 31 00 00, earthwork. It outlines materials and testing standards, including sieve sizes for base and subbase aggregates. Furnish each aggregate material from single source throughout the work. Sand gradation 1s or 2s conforming to section 801 of scdot standard

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. This guide specification covers the requirements for base course to be used directly under bituminous pavement courses. Provide crushed material having a minimum compressive strength of 45 psi at 0 psi lateral pressure and 175 psi at 15 psi lateral pressure using triaxial testing procedures. This document outlines specifications for aggregate base course material used in road construction projects.

The work provided under this specification shall include the furnishing, placement and compaction of aggregate base course (abc) to the lines, grades, dimensions, moisture, density and typical sections as specified in the plans and specifications, and or as directed by the engineer. This document specifies requirements for aggregate base and subbase courses used in road construction. Aggregate bases are designated as class 2 or class 3. Base course for rigid paving and select the words rigid pavement base course throughout.

Brief Specifications Of The Materials Are Given Below.

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. Aggregate bases are designated as class 1 or class 2. The document outlines the dpwh standard specifications for various aggregate and stabilized base course materials used in road construction. The class of aggregate base shall be as indicated.
