2017 Work Plan Accomplishments Safety NCHRP Project 20-05, Synthesis Topic 49-04, Very Short Duration Work Zone Safety for Maintenance and Other Activities Workforce Development Promoted the development of Contractor and Agency Pavement Preservation Treatments Certificate Programs. Co-Hosted webinar on ID/IQ Contracting for Preservation.

2017 Work Plan Accomplishments Communication Provided webinars in focus areas. Use of Thin-Lift Asphalt Surfaces for Pavement Preservation, TechBrief. Microsurfacing, Slurry Seals and Chip Seal Quality Assurance Best Practices TechBrief. Research Assisted implementation of SHRP-2 products that are useful to pavement preservation and maintenance.

2018 Work Plan Quantifying the safety benefits of pavement preservation High Friction Surface treatments Rut filling to reduce hydroplaning Diamond Grinding and Grooving Identify agencies that consider safety alone as the trigger for a pavement preservation program Look at operational safety between preservation and rehabilitation projects and/or safety of pothole patching operations vs. preservation projects. Support efforts to emphasize the importance of pavement preservation to asset management Provide examples for how pavement preservation has been incorporated into Asset Management Plans in other States Look at the ability to link pavement preservation to the lowest life-cycle cost

2018 Work Plan Support TC3 and the implementation of the TSP2 contractor and agency pavement preservation certification program Recommendation for Implementation NCHRP 14-37 Guide Specifications for the Construction of Chip Seals and Microsurfacing NCHRP 20-07(380) Proposed AASHTO Manual for the Maintenance of Roadways and Bridges NCHRP 14-31 Pavement Maintenance Data Base

2018 Research Problem Statements 1. Determining Pavement Preservation Treatment Lives and Related Pavement Life Extension The objective of this project is to develop methodologies to estimate treatment lives and life extension of both flexible and rigid pavements as a function of treatment type, existing pavement conditions, and environmental and traffic conditions. It is anticipated that existing databases and PMS data will be used to develop these methodologies and estimates for case studies. 2. Guide Construction Specifications for Cold In-place Recycling (CIR) and Cold Central Plant Recycling (CCPR) The objective of this project is to produce an AASHTO Construction Guide Specification for the application of cold in-place recycling and cold central plant recycling. 3. Development of Protocols and Procedures for Selecting, Monitoring and Reporting on Pavement Preservation Treatments for Performance Evaluation The objective of this project is to develop detailed guidelines that can be used by state and local transportation agencies to create, monitor, analyze, and report on pavement test sections for the purpose of evaluating the effectiveness of different pavement preservation treatments.

2018 Resolutions Establish the Committee on Maintenance as the Responsible Body for Pavement Preservation Treatment Construction Guidance Specifications Thank Marc Hoelscher for his service to SCOM
