During the week of August 19, AASHTO’s Committee on Maintenance is conducting its 2021 virtual annual meeting. The annual meeting consists of two general sessions and several Technical Working Group (TWG) meetings.

The Pavement TWG met on July 19 and July 21. The first pavement TWG meeting consisted of providing updates by AASHTO, FHWA, and Industry. The IGGA/ACPA provided an update on the TSP2 concrete ETG activities. The TSP2 ETG had previously developed a diamond grinding standard/guideline for pavement preservation. These guidelines will be posted on the recently created AASHTO electronic supplement which should be available at the end of August/ early September. This is the first of several concrete preservations/standards that will be developed by the ETG and the first published by AASHTO.

The second pavement TWG meeting included four presentations:

  • NCHRP 51-16 Synthesis on Maintenance and Surface Preparation Activities Prior to Pavement Preservation
  • Pavement Maintenance Activities- Best Practices Field Guides
  • Using a New Crack Density Metric in Pavement Management
  • National Roadway Research Alliance Update
