Aggregate Base Course Specification

Aggregate Base Course Specification - Coarse aggregate type a or b with a gradation of abc conforming to section 801 of scdot standard specifications. It defines two classes of aggregate bases, class 1 and class 2, and specifies the material requirements and testing standards for each. The class of aggregate base shall be as indicated. This guide specification covers the requirements for base course to be used directly under bituminous pavement courses. Preparation of sub grade is specified in contract specifications section 31 00 00, earthwork. Provide crushed aggregate that meets the gradation shown in table 1 when tested in. Aggregate bases are designated as class 2 or class 3. The document outlines the dpwh standard specifications for various aggregate and stabilized base course materials used in road construction. This document provides specifications for aggregate base courses used in construction projects. The class of aggregate base shall be as indicated.

It defines two classes of aggregate bases, class 1 and class 2, and specifies the material requirements and testing standards for each. 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. Preparation of sub grade is specified in contract specifications section 31 00 00, earthwork. Provide crushed aggregate that meets the gradation shown in table 1 when tested in. Brief specifications of the materials are given below. The document outlines the dpwh standard specifications for various aggregate and stabilized base course materials used in road construction. Base course and specification and construction and method. 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. It outlines materials and testing standards, including sieve sizes for base and subbase aggregates. The class of aggregate base shall be as indicated.

The Class Of Aggregate Base Shall Be As Indicated.

Sand gradation 1s or 2s conforming to section 801 of scdot standard The document outlines the dpwh standard specifications for various aggregate and stabilized base course materials used in road construction. Aggregate bases are designated as class 1 or class 2. 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.

This Document Provides Specifications For Aggregate Base Courses Used In Construction Projects.

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. Coarse aggregate type a or b with a gradation of abc conforming to section 801 of scdot standard specifications. It defines two classes of aggregate bases, class 1 and class 2, and specifies the material requirements and testing standards for each. 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.

Furnish Each Aggregate Material From Single Source Throughout The Work.

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 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. Brief specifications of the materials are given below. Construct base course in layers not less than 3 inches (75 mm) nor more than 6 inches (150 mm) compacted thickness.
