Notice is hereby given that the SCDOT will accept electronic bid proposals for the highway improvements. Cement Modified Recycled Base (12" Unif)-curing Method B, HMA Shoulder Widening Course, Guardrail, Hot Mix Asphalt, Pavement Markings 18.80 Miles. This work shall consist of satisfactory placement of all materials necessary to bring the shoulder grade to within 2 inches of the final pavement edge grade. The Contractor shall furnish all earth material necessary to eliminate any edge of final pavement to shoulder gradient differential that exceeds 2 inches. The quantities shown on the plans are the Engineering estimate of the number of units that will be necessary for this project, actual field measurements may cause these quantities to vary. Selected materials shall be used for this operation. The selected material shall consist of a friable material such as topsoil, etc., containing grass roots and having the properties of being comparatively porous, capable of growing grass and of a stable nature in that when compacted it will resist erosion and be capable of supporting vehicles when relatively wet. When the area where material is to be placed, is greater than 4 feet in width, it shall be scarified and/or disked to a minimum depth of 3 inches prior to placing any material. Scarifying or disking is not required for areas less than 4 feet in width. Borrow shall be mixed with the existing scarified and/or disked shoulder material in such a manner as to provide a seed bed in accord with Section 810.15 of the Standard Specifications. The Contractor has the option of placing the borrow material (a) Prior to placing final surface course or (b) Following the placing of the finished surface course. The excavation necessary for the placing of the asphalt for widening shall be performed in accordance with Section 203 of the Standard Specifications. The material shall be pulverized and placed on the adjacent shoulder or loaded into trucks to be hauled off, as directed by the RCE. The removed section shall meet the depth and width as specified for the roadway. No more material shall be excavated in one day than can be replaced with bituminous material. The pulverized material may be used to backfill the existing pavement, shape and dress shoulders provided the material is free of excessive rocks, millings and other non-soil materials that are incapable of growing grass. The RCE may prohibit the use of this material as the final dressing on the shoulders if in his opinion the material will not provide an established grass shoulder. The final shaping of the shoulder and slopes shall be performed after all the bituminous materials are placed. Payment for this excavation shall be paid by the number of stations required for the entire length of each shoulder. Bond required please refer to documents for further details. This project encouraged M/WBE participation.
