High Friction Surface Treatment Initiatives By Indot: Spec Development, Joseph Bruno
High Friction Surface Treatment Initiatives By Indot: Spec Development, Joseph Bruno
Purdue Road School
In-House Project Design, Special Provision Specification, and Initial Test Results—Highfriction surface treatment (HFST) has been proactively utilized as a cost-effective solution to reducing vehicle crashes at curves across the country. As an initiative, INDOT is currently installing HFST at 26 locations statewide, mainly horizontal curves with high crash rates. This session consists of two presentations to share the information on the development, expected benefits, project design, and initial test results based on the HFST at these locations.

Have you ever found yourself in the public's cross-hairs when it is time to implement a few roadway improvements? Are you handicapped in your ability to describe the true value of community planning and economic development planning? Come hear from one dynamic trio with the ability to identify issues and opportunities that others might not see and work to uncover even more ways tin which we are better together.

This presentation highlights the progress INDOT has made in improving safety at horizontal curves by upgrading the signing and delineation and by applying high friction surface treatments at some locations. We will also discuss the MUTCD (Manual on Uniform Traffic Control Devices) requirements for signing horizontal curves and the approaching (December 31, 2019) FHWA target date for compliance.

Mowing activities are usually reported by daily work orders and it is difficult to obtain quantitative information characterizing the utilization and productivity of the mowing operations. This research uses telematics data from commercial sensors to track the daily activity of seven mowers in the Fort Wayne district. Weather data from NOAA was also captured to estimate the weather related delays. During a one-month period, the mowers collectively covered a total of around 1170 miles and an area of nearly 1800 acres of mowing. Crews worked alternative work schedules with extended hours four days a week. On an average 9.5 hour …
