alb <br />• <br />7r <br />5. STABILIZED SHOULDERS <br />A. Stabilized shoulders shall be constructed on each side of the paved <br />roadway section to the width, depth and slope as shown on the Plans and <br />Typical Sections. The stabilized shoulder material shall have a minimum <br />' . Limerock Bearing Ratio of 40 as determined by the Limerock Bearing <br />Ratio Test. In an area where the bearing ratio is less than 40, stabilizing <br />material approved by the Engineer shall be furnished by the Centractor, <br />r spread, and mixed thoroughly throughout the entire depth and width of <br />the stabilizing limits. No specific density will be required and compaction <br />r shall be only to the extent directed by the Engineer. <br />I 6. COMPACTION TESTING <br />A. In general, Limerock Bearing Ratio tests on the subgrade shall be taken <br />f at approximately 300 lineal foot intervals. Exact locations will be <br />` designated by the Engineer. <br />B. The maximum dry density of the subgrade material shall be determined by <br />the Modified Proctor Test using the procedure as described by ASTM <br />a D1557 or AASHTO-T180 (Method A). In general, there shall be one <br />Modified Proctor Test per 300 lineal fact at a location which is <br />representative of the type of subgrade material used on the project. Each <br />material which is inherently different in composition from other subgrade <br />material and which is used over a widespread area of the project, will <br />necessitate an additional Modified Proctor Test. <br />v <br />sm <br />
