Innovation Implementation: High-Friction Surface Treatments
High-friction surface treatments are applied to pavements to provide more surface friction in critical locations, such as sharp horizontal curves, steep hills and intersections. They can help motorists maintain control and reduce crashes.
As part of Every Day Counts, high-friction surface treatment technology has seen wide acceptance. Twenty-one states have completed demonstration projects, including eight that have institutionalized the technology. Another dozen are conducting demonstrations.
- The California Department of Transportation has completed 33 high-friction surface treatment projects and about 30 local agencies are working on projects. An estimated 250-plus state and local locations are expected to be treated by the end of 2015.
- The Illinois Department of Transportation developed a special provision and is working on three high-friction surface treatment projects. Two more are scheduled for procurement.
- The South Carolina Department of Transportation modified its high-friction surface treatment specification to align with the new American Association of State Highway and Transportation Officials specification. Use of the treatment is considered common practice in the state.
FHWA Approves CREATE Project Documents
The Federal Highway Administration has approved a combined final environmental impact statement and record of decision for the 75th Corridor Improvement Project, the largest project in the Chicago Region Environmental and Transportation Efficiency Program. The CREATE Program is a partnership involving FHWA, the Illinois and Chicago Departments of Transportation and the Association of American Railroads to cooperate on regional projects to improve the rail and roadway transportation network. The purpose of the 75th Corridor project is to reduce highway-rail crossing and local mobility problems and improve rail transit passenger service. Completion is set for 2021.
Illinois to Use STIC Funds for 3-D Implementation
The Illinois State Transportation Innovation Leadership Team recently supported an application for $100,000 to aid implementation of 3-D modeling at the Illinois Department of Transportation. Funds from FHWA's State Transportation Innovation Council Incentive program have been approved for training and equipment to implement 3-D modeling into processes associated with the design, construction and operation of the Illinois transportation infrastructure.
Rhode Island Bridge to Include Prefabrication
The Rhode Island Department of Transportation and FHWA conducted a value engineering workshop for the second phase of the I-95 Providence Viaduct replacement. The $120 million project, set to begin in 2016, will complete the replacement of the viaduct. It incorporates prefabricated bridge elements and systems, including prefabricated substructure units, prefabricated superstructures moved into place with the slide-in bridge technique and self-propelled modular transporters, and precast deck panels. It uses the construction manager/general contractor delivery method, which could result in potential savings of nearly $10 million.
Virginia Hosts Workshop on Local Program Administration
More than 400 people attended the Virginia Department of Transportation's annual workshop on administering local transportation programs in Roanoke. The September event, with a theme of "Network for Success," brought together representatives of local and state government and the private sector for an overview of local program management and project development. The two-day workshop featured 20 sessions on local program topics. FHWA, a workshop sponsor, staffed a booth with information on Every Day Counts and the Federal-Aid Essentials for Local Public Agencies website.
FHWA Report Highlights Local Agency Certification
A new FHWA report provides an overview of a virtual peer exchange the Washington State Department of Transportation hosted to discuss its local public agency certification program challenges and successes. Local Public Agency Peer Exchange on Certification Programs highlights key information and documents questions and answers from the June 2014 meeting. Participants discussed the Washington State DOT's Certification Acceptance Program, including the certification process, project administration, and monitoring and oversight.
