Pavement surfaces become polished over time due to traffic and weather conditions, leading to more wet weather crashes. Macrotexture refers to the texture of the pavement due to the arrangement of aggregate particles. This has a strong influence on vehicle-roadway skid resistance. TRB will host a webinar on Thursday, October 27, 2022 from 2:30 PM to 4:00 PM Eastern that will discuss protocols for test methods, equipment specifications, and data quality assurance practices for network-level macrotexture measurement. Collecting accurate and repeatable texture data provides agencies with valuable information that will help identify high risk locations for wet weather crashes.

This webinar is based on NCHRP Report 964: Protocols for Network-Level Macrotexture Measurement.

This webinar is sponsored by the TRB Standing Technical Committee on Pavement Surface Properties and Vehicle Interaction.

Registration is free for employees of TRB sponsors as well as Titanium and Cobalt Global Affiliates. The registration rate for all other attendees is $60. Sign into to view registration information. Contact Patrice Davenport to inquire about becoming a TRB sponsor or global affiliate organization.

A recording will be sent to all registrants after the webinar.
