1) Tire/pavement and environmental traffic noise research study

Author

Description

Following a rigid set of testing protocols, data is being collected on highway traffic noise characteristics along with safety and durability aspects of the associated pavements. The overall goal of this research project is to develop and execute a comprehensive, long-term study to determine if a particular pavement surface type and/or texture can be successfully used in Colorado to help satisfy FHWA noise mitigation requirements.

Read Description

This report presents information and data produced by the Colorado Department of Transportation's long-term study of Portland cement concrete pavement (PCCP) textures used within the state. The information includes vehicle accident, friction, and texture data. This information was used as the for a review of proposed revisions to the CDOT texture measurement method, CP-77, and a specification for PCCP texturing found in Sections 106 and 412 of the...

Description

Read Description

Traffic noise abatement in mountain corridors can be difficult because traditional roadside barriers may be ineffective due to topography or may not fit the setting. This study examined current best practices from around the world to gather concepts for mitigating traffic noise in mountain corridors in Colorado. A literature review of prospective noise abatement actions found that noise barriers are the most effective direct noise abatement measure,...

Description

Read Description

This research project reviewed potential noise barrier materials made from scrap tires, selected a material for field testing, designed and built a test barrier at the designated site using the material, and monitored barrier performance for one year. The material selected was a railroad tie replacement made from scrap tire treads
