Agenda

Every Day Count

EDC was designed to identify and deploy innovation. The Program Principal goals are:

• Shorten project delivery
• Enhance the safety of our roadways
• Protect the environment

Why EDC-II?

“We are continuously looking for new ideas, working with stakeholders to bring new products and innovative processes to market.” – Victor Mendez Challenge… to make Every Day Count!

What is a High Friction Surface Treatment?

• High Friction Surface Treatments (HFST) are

pavement surfacing systems with exceptional skid- resistant properties that are not typically acquired by conventional materials

• Generally proprietary resin-based products and

processes

GOALS & Performance Measures

GOAL

– To advance the rapid deployment of High Friction Surface Treatments (HFST) by working with agencies, contractors, consultants, and industry to increase the knowledge and skills to apply this recommended countermeasure on horizontal curves, intersection approaches, and high-priority locations as identified, in order to decrease crashes, injuries and deaths.

Performance Measure

– By December 2014, all states with Roadway Departures and Intersections as an emphasis area in their Strategic Highway Safety Plan (SHSP) have developed and implemented a process to screen or identify potential HFST locations in their Highway Safety Improvement Program

HFST Technology Descriptions

• HFST reduce crashes, injuries, and fatalities.
• Provides an overlay option.
• Supplies more friction than traditional overlays.
• Holds the higher friction property for a much

longer time.

• Restores available friction.
• minimal impact to traffic during construction
• and the negligible environmental impact

HFST Aggregates

– Generally calcined bauxite or slags with high PSV, but flint, granite, and other materials have also been used. – Generally 3-4 mm maximum size

Flint Bauxite Granite

HFST Binder Materials

• Binder system (proprietary blends)

– Bitumen-extended epoxy resins – Epoxy-resin – Polyester-resin – Polyurethane-resin – Acrylic-resin

HFST Installation

• Manually

– Manual mixing of epoxy material – Manual application of epoxy with squeegee – Hand broadcast and distribution of aggregate – Production rates: 200-500+ SY/hr.

HFST Installation

• Automated (machine-aided)

– Machine mixing and application of epoxy (limited hand/squeegee work) – Machine broadcast/application of aggregate – Production rates up to 2,300 SY/hr.
