Subgrade Preparation. Prepare subgrade to receive surface course Material at locations as designated on-the-ground by the Forest Service on roads listed below. Prepare the subgrade by shaping the Roadbed to approximately the original cross-section and consistent with adjacent sections.
Subgrade Preparation. The subgrade area of the street right-of-way shall be cleared of brush, weeds, vegetation, grass and debris. All cleared and grubbed materials shall be satisfactorily disposed of. The existing grade shall be excavated to bearing soil as approved by the design engineer and approved by the City Engineer. The subgrade shall be compacted to a minimum density and be witnessed by the City inspector. Compaction tests may be required to be conducted at the discretion of the City to verify same. All subgrade preparation shall be completed in conformance with the Washington State Department of Transportation Standard Specifications.
Subgrade Preparation. Remove vegetation and other deletarious materials from the existing road surface. Shape the existing road surface to a smooth surface, with a 2% crown at the road centerline, conforming with Figure 1. Construct drain dips as shown in Figure 2 where directed by the Contracting Officer. Adjust depth of drain dips as necessary to avoid ponding of water on or adjacent to the road. Where joining to existing gravel-surfaced road segments, adjust slopes to gradually blend into adjacent road segments. Remove all surface rocks over 3” in diameter. Compact subgrade using roller compaction as specified below. Roller Compaction. Adjust the moisture content to a level suitable for compaction. Operate Rollers over the full width of the subgrade layer until visual displacement ceases, but not fewer than three complete passes. Fill depressions as necessary to provide a smooth and uniformly compacted subgrade surface. Use vibratory steel wheeled rollers equipped with amplitude and frequency controls with a minimum weight of 6 tons, specifically designed to compact the material on which it is used.
Subgrade Preparation. Prepare Subgrade to receive Surface Course Material at locations as designated on-the-ground by the Forest Service on roads listed below. Prepare the Subgrade by shaping the Roadbed to approximately the original cross-section and consistent with adjacent sections. 3.2 Furnish, haul and spread Material at locations designated on the ground by the Forest Service (FS). Compact the aggregate by operating spreading and hauling equipment over the full width of each layer of the aggregate, or by other methods as specified below. Road Number Type Material Finished Compacted Thickness Specified Total Quantity (Tons or cu.yds.) Compaction Method 1006 2” Base Crushed Aggregate 2” 15 tons N/A 3.3 Variations. The Purchaser will be required to furnish weight tickets to the FS for each load of commercially obtained crushed aggregate prior to the final inspection. For aggregate purchased from the government, a count of truck loads will be required in addition to finished depth checks for the placed and compacted aggregate. Widths and lengths will be as staked or from schedule. When it is mutually agreed that all or part of the Surface Course Material is not needed, the estimated cost of surfacing not placed shall be charged to the Timber Sale Account in accordance with BT8.31.
