KSDOT- 251 - Milling and HMA Overlay - US 281 This specification is for coarse aggregates, intermediate aggregates, fine aggregates, mixed aggregates (coarse, intermediate and fine material) and miscellaneous aggregates for use in construction of concrete not placed on grade. For Intermediate Aggregates and Mixed Aggregates, consider any aggregate with 30% or more retained on the No. 8 sieve to be Coarse Aggregate. This specification covers the quality, composition and gradation requirements of aggregates for hot mix asphalt (HMA) on QC/QA projects. This specification covers aggregate for backfill. Use this when structures, pipe, mechanically stabilized earth (MSE) walls (panel or modular), underdrain, permeable or crushed stone backfill requirements are specified in the Contract Documents. This specification covers stone for the following uses: o Riprap o Aggregate Ditch Lining (D50) o Filter Course o Flumes, Flume Drains and Slope Drains o Tree Wells or Cribs o Shot Rock o Granular Drainage Blanket o Sediment Basin Risers Where referred to, quarried stone is defined as limestone, dolomite, calcite cemented sandstone, rhyolite, quartzite, basalt and granite, removed from naturally occurring formation by standard extraction and sizing methods. Recycled PCCP may be used for Riprap, Ditch Lining, and Shot Rock, provided the respective Soundness and Wear requirements are met. This specification is for coarse aggregates, intermediate aggregates, fine aggregates, mixed aggregates (coarse, intermediate and fine material) and miscellaneous aggregates for use in construction of concrete placed on grade. For Intermediate Aggregates and Mixed Aggregates, consider any aggregate with 30% or more retained on the No. 8 sieve to be Coarse Aggregate. This specification covers admixtures for use as air-entraining agents to be added to concrete mixtures. An air-entraining agent is defined as an admixture that is used as an ingredient of concrete, added to the batch immediately before or during mixing, for the purpose of entraining air. This specification covers evaporation retarding material for use in finishing concrete flatwork, and serves as a finishing aid. This material is not a substitute for regular curing compound, which must be applied after the concrete is finished. This specification covers liquid membrane forming compounds (also referred to as concrete curing compounds) suitable for spraying on horizontal and vertical concrete surfaces to retard the loss of water during the early hardening period and subsequent curing period. This specification covers materials in sheet form used for covering the surfaces of hydraulic cement concrete to inhibit moisture loss during the curing period. In the case of white reflective materials, it also reduces temperature rise in concrete exposed to radiation from the sun. Materials included are clear and white opaque polyethylene film, and white-burlap polyethylene sheet. This is the method of price adjustment for fuel (regardless of the type of fuel) used on various items of work involved in the construction of the Project. This specification applies when 10-10-00-Required Contract Provision Price Adjustment for Fuel, latest revision, is a part of the contract, and the Contractor accepts that provision. This is the method of price adjustment for emulsified materials (regardless of the type) used on the project. This specification applies when 08-31-09-Required Contract Provision Price Adjustment for Emulsified Asphalt, latest revision, is a part of the contract, and the Contractor accepts that provision. Remove and dispose of the existing structures as specified in the Contract Documents. Existing structures include the structures identified in the Contract Documents for removal, and man-made structures not specifically identified in the Contract Documents that are in conflict with the new construction and would normally be encountered upon a careful examination of the work site. Excluded are utilities and structures for which other provisions are made for removal. Protect any structures designated to remain. Remove, clean and store any materials designated for salvage. Remove, clean, store and reconstruct any existing structures as designated in the Contract Documents. Inspect all building structures that are scheduled for removal, and determine if asbestos is present. BID ITEMS UNITS Removal of Existing Structures Lump Sum Removal and Reconstruction of Existing Structures Lump Sum This specification covers the following five types of products: a. Joint compound for filling and sealing joints in concrete and vitrified clay pipe. b. Flexible gasket type joint material for filling and sealing joints in concrete and vitrified pipe. c. Factory molded joint rings for use on standard or extra strength clay pipe. d. Materials for sealing joints in cast iron pipe. e. Expanded closed-cellular rubber gaskets for filling and sealing joints in reinforced concrete pipe and boxes used for drainage and storm water lines. Determine the smoothness of the pavement surface and correct the deficiencies as specified in the Contract Documents. For the purposes of this specification, define new construction to mean construction where pavement did not exist before, and where existing pavement is removed down to the base or subgrade. All other conditions should be considered rehabilitation construction. When projects contain both new and rehabilitation construction, follow appropriate guidelines for each type. BID ITEM UNITS Asphalt Pavement Smoothness Lump Sum Construct the designated class of HMA-Commercial Grade asphalt pavement, as shown in the Contract Documents. Class A HMA-Commercial Grade is intended for all areas that are not Class B locations. Class A includes permanent traffic areas and temporary traffic areas with moderate to high volumes of vehicular traffic such as driving lanes, auxiliary lanes and shoulders.
