The purpose of this pooled fund study (Part 3) is to fully implement the PCC Surface Characteristics program. This project is related to a larger study involving two other parts (Part 1 and 2). Those two parts are summarized in the attached Appendix B. Part 3 will consist of the continuation of the comprehensive data collection and analysis program on new and existing pavements started in 2005; expand on it so that the research results have a broader range of applicability; and develop innovative texturing techniques that have the potential to significantly reduce noise.

At the completion of this overall study, it is anticipated that it will be possible to specify the desirable surface characteristics of individual projects prior to construction to meet the site specific requirements for noise, skid, texture, and smoothness.

States included in the pooled fund will be funding part of the field measurements and coordination of work for the new sites. This work will target those projects from the earlier phase of the field study (Part 2) that show good results and are worth further evaluation relative to constructability and consistency. Also included will be projects that will involve new, innovative processes or equipment that is developed as the project moves forward. In addition, the pooled fund will cover the cost of the on-going technology transfer that will provide the States the results of the overall study (Parts 1, 2, and 3) and the ways that they can incorporate the study results into their activities to meet noise, friction, and safety requirements. The technology transfer elements will be centered around on-site meetings with the management level staff members of each of the participating states. The technology transfer program will also include technical memorandums and conference presentations indicating the study results and recommendations. Participation in the pooled fund does not require involvement in field site activities. States involved with the project that participate in field experiment sites will be required to provide staff and financial resources. The involvement varies in accordance with the type of project involved. Type 1 (new) projects will involve the following activities: -Pay for extra contractor costs for different textures that are to be used -Provide traffic control for all testing activities -Complete friction tests utilizing an ASTM E274 trailer along with an ASTM E 524 smooth tire Type 2 (existing) and 3 (existing and new) projects will involve the following activities: -Provide traffic control for all testing activities -Complete friction tests utilizing an ASTM E274 trailer along with an ASTM E 524 smooth tire
