Pavement Friction Management Program Utilizing Continuous Friction Measurement Equipment and State-of-the-practice Safety Analysis Demonstration Project - Final Report General Interest: provides practical guidance to engineers responsible for the day-to-day design, construction, rehabilitation, maintenance, and management of pavements.

Primary Topic: Pavement Management

Description: This report details the results of using a continuous friction measurement equipment (CFME) system, the Sideway-force Coefficient Routine Investigation Machine (SCRIM), to perform network-level friction measurements and compare it to a traditional locked-wheel skid tester (LWST). The report summarizes the results of (a) performing SCRIM and LWST friction testing in four States; (b) collecting comprehensive historical friction, crash, and other data from the four States; (c) analyzing the data to identify appropriate investigatory friction and investigatory macrotexture levels; and (d) providing guidance on how to compile and analyze friction and crash data to further the development of a pavement friction management plan (PFMP) and implement it into practice. The research team also prepared a separate document with recommended revisions to the 2008 AASHTO Guide for Pavement Friction to provide additional insight and guidance on the development of pavement friction management (PFM) programs using CFME. The recommended revisions to the AASHTO Guide, together with this report, will provide a much greater level of detail regarding the steps an agency should take in developing a PFM program. It will also address development and implementation barriers, and how they can be overcome by agencies attempting to develop a PFMP using CFME.
