Site work and paving for a road / highway in Needham, Massachusetts. Completed plans call for site work for a road / highway; and for paving for a road / highway.

Estimated contract value is based on 3-year total The Town of Needham is requesting sealed bids for all labor and materials necessary for the application of three road surface treatment types as requested. All surface treatment equipment, material and application types must conform to MassDOT Standard Specifications for Highways and Bridges (2026 edition or subsequent most current edition) and with the Manual on Uniform Traffic Control Devices (MUTCD, 11th Edition with Revision 1 or subsequent most current edition). All materials shall comply with DEP and EPA regulations and standards. Bid Item 1: Micro-Surfacing Micro-surfacing is a smooth and durable thin overlay material which can restore the original service properties to worn but structurally sound pavements. Its properties are based on a blend of select crushed aggregate and a sophisticated chemical formulation of asphalt cement, cationic emulsifiers, additives, and polymers. This specification covers all materials, equipment, construction, and application procedures for the rut filling and/or surfacing of existing paved surfaces. The micro-surfacing shall be a mixture of cationic, polymermodified asphalt emulsion, mineral aggregate, mineral and field control additives, and water, properly proportioned, mixed, and spread on the paved surface in accordance with this specification and as directed by the Engineer. For this contract, additional micro-surfacing mixture additives shall be utilized for the purpose of improving performance and durability. These mixture additives shall include heavy polymer dosages in the emulsion (6% SBS polymer and referred to as "HiMA", or "Highly Modified Asphalt"), and all additives shall be homogenously blended with the other micro-surfacing components. Bid Item 2: Asphalt-Rubber Surface Treatment with Aggregate Cover (20% Rubber) Asphalt-Rubber Stress Absorbing Membrane (otherwise known as SAM or as Rubber Chip Seal) is a hot spray application of 20% asphalt-rubber followed by a layer of heated and treated cover aggregate. The road surface is able to be swept immediately following rolling to pick up any loose aggregate. The application provides a flexible, waterproof wearing surface that seals the existing pavement and is highly resistant to cracking. The treatment can also be used as an interlayer (SAMI) before a hot mix overlay to help decelerate reflective cracking. This specification covers all materials, equipment, construction, and application procedures for utilizing asphalt-rubber treatments as a stress absorbing membrane (SAM) or a stress absorbing membrane interlayer (SAMI) as well as a surface layer. Bid Item 3: Bonded Wearing Course Bonded Wearing Course is an ultrathin overlay that seals the existing road surface and provides a new, skidresistant, smooth and thin (5/8" to 3/4") hot mix asphalt (HMA) wearing course in one simultaneous operation. It provides a durable, open-graded, drainable wearing surface on existing pavements. This specification covers all materials, equipment, construction, and application procedures for pavement micro milling, resetting/adjusting of utility castings, installation of an HMA leveling course, installation of a bonded wearing course (BWC), and all other specified and incidental work on bituminous concrete roadways.
