City of Santa Ana Pavement Management Program Update RFP No, 19-070 August 6, 2019 pavements contribute to global warming because they radiate heat into the atmosphere. Cool pavements are made with different surfaces to increase albedo, thereby reflecting ultraviolet radiation out of the atmosphere. Increasing albedo reduces heat transfer to the surface and creates local cooling. Composite Pavements — NICE worked for the Strategic Highway Research Program (SHRP2 R21) to develop best practice standards for asphalt concrete (AC)/portland cement concrete (PCC) composite pavements nationwide. This project resulted in the development of best practices in construction, specifications, and quality management procedures for these pavements. NICE is currently teaching a series of workshops for State Highway Agencies nationwide to assist them in implementing key best practices for composite pavements. While this work was funded and ai the fundamental concepts of composite pavements and the best ways to implement them can be translated to cities, too. Cold -in -place recycling (CIR) — A cost-effective alternative to traditional mill and fill pavement treatments, cold -in -place recycling can yield cost savings of as much as 30% by the use of existing AC materials, which produces less truck hauling and better time efficiency during construction. The technology involves milling of existing AC, pulverizing, and processing it to a specified material size, adding emulsion, mixing, and then placing and compacting it onto the roadway. A thin AC overlay is typically placed as a smooth wearing course. Longer pavement sections (generally at least 500,000 square feet of pavement area) that require deeper mill and fills (typically at least three inches) are good candidates for cold -in -place recycling with potentially large cost savings. Full -depth reclamation (FDR) — Full -depth reclamation is a process that reconstructs failed AC pavements by recycling the existing roadway materials. The old AC and aggregate base materials are pulverized and mined using specialized equipment. The full -depth reclamation method recycles the materials in -situ and can offer significant cost savings over conventional roadway reconstruction techniques. It is generally cost-effective for areas as little as 25,000 square feet. City Owned Asset Collection As an optional service (costs can be provided upon request), NICE can collect additional transportation related asset information in the field concurrent with the pavement condition survey. Mobil data collection units gather high -resolution 360-degree geo-referenced right-of-way street level digital imagery along with 3D point cloud data. Assets collected can include curb/gutter, ADA compliance, streetlights, traffic signals pavement markings, pavement, sidewalks, drainage facilities, signage (including reflectivity), parking lots bike trails, and pathways/walkways. a We have and can work with the City to develop G` I( customized condition rating standards where none exist. a The data are entered into a database, either proprietary software, such as StreetSaverO, or custom Page 16 25D-19
