Presentation Notes

FHWA is actively working with stakeholders from State Departments of Transportation and other public agencies, industry and academia to advance sustainable pavement engineering practices. Early 2015 we published “Towards Sustainable Pavements: A Reference Guide”, which is the first of its kind to benchmark pavement sustainability. The document highlights technologies and practices that can be implemented today throughout the pavement life cycle, from materials acquisition to end-of-life to increase sustainability. It is important to note that there is not one definition of sustainability. Sustainability is about moving the benchmark; it is a journey and not a destination. We are working to provide tools such a Tech Briefs, Technical Articles, Webinars, and updates to our website to inform States such as New Mexico about how to incorporate sustainability into daily practices. We are now focusing on developing guidelines on quantifying the environmental impacts of pavements, which is done through an Environmental Life Cycle Assessment for pavements. These guidelines will help an agency assess the “environmental footprint” of a strategy or pavement system.

Quality Assurance Program and Materials Training

• Assumption – Pavement density can be increased with a minimum of additional cost.

• Long-Term Objective – States will increase their in-place asphalt pavement density requirements resulting in increased pavement life.

Enhanced Durability through Increased In-Place Pavement Density

• A 1% increase in field density (1% less air voids) is claimed to increase asphalt pavement service-life 10+%! (conservatively)

• Today’s compaction target is typically 92% of maximum (Gmm ) (8% air voids), with varying requirements for the area near the longitudinal joint

Enhanced Durability through Increased In-Place Pavement Density

Increased Density Pavements target a 1-2% increase across the entire pavement!

– Just 1% more… makes a huge difference!

Summary of National & Emerging Asphalt Issues

Presentation Notes

Accelerating implementation of innovation has been and remains a focal point for FHWA. The Technology and Innovation Deployment (TIDP) Program authorized by MAP-21 (MAP-21 §52003; 23 USC 503) and continued in FAST funds efforts to accelerate the implementation and delivery of new innovations and technologies that result from highway research and development to benefit all aspects of highway transportation. The law authorized $62.5M per year. Program goals to: Significantly accelerate the adoption of innovative technologies by the surface transporation community; Provideleadership and incentives to demonstrate and promote state-of-the-art technologies, elevated performance standards and new business practices in highway construction processes that result in improved safety, faster construction, reducted congestion from construction and improved quality and user satisfaction; Construct longer-lasting highways through the use of innovative technologies and practices that lead to faster construciton of efficient and safe highways and bridges; Improve highway efficiency, safety, mobility reliability, service life, environmental protection and sustainability; and Develop and deploying new tools, techniques, and practices to accerlate the adoption of innovation in all aspects of highway transporation Every Day Counts is a major effort under TIDP and is explicitly provided for in the FAST Act. Another significant program seeks to accelerate project delivery and technology innovation developed through the SHRP 2 research. We’ll be wrapping this up over the next two years. Additionally, both MAP-21 and FAST set aside $12M per year to accelerate the deployment and implementation of pavement technologies .

Every Day Counts

• EDC-1 - 14 Innovations (2011 – 2012) • EDC-2 – 13 Innovations (2013 – 2014) • EDC-3 - 11 Innovations (2015 – 2016) • EDC-4 - 80+ Proposals being reviewed

Presentation Notes

Every Day Counts is a state-based model to identify and rapidly deploy proven and underutilized innovations to shorten the project delivery process, enhance roadway safety, reduce congestion and improve environmental sustainability. EDC-1 – Launched in 2010. There were 14 innovations that were promoted during 2011 and 2012. In the end of 2012, a new set of 13 innovations, were selected for deployment through EDC-1. Some of these innovations were hold-overs from EDC-1. Every state adopted one or more of these 13 innovations deployed during the EDC-2 two-year deployment cycle. Currently, under EDC-3, we are promoting and supporting deployment of 11 innovations and they are: 3D Engineered Models e-Construction eNEPA and IQED GRS-IBS Railroad Coordination Regional Models of Cooperation Road Diets Smarter Work Zones Stakeholder Partnering Ultra-High Performance Concrete Connections Data-Driven Safety Analysis An RFI to solicit stakeholder input on the innovations to be included in EDC-4 was published on December 10, and will remain open until January 1, 2016

Presentation Notes

SHRP2 Authorized in SAFETEA-LU and in MAP-21, the Second Strategic Highway Research Program (SHRP2) builds on the success of the original SHRP program and provides highway organizations with research products designed to address critical challenges in Four Focus Areas: Safety, Renewal, Reliability, Capacity, such as aging infrastructure, congestion, and safety. The 65 distinct research products, or “SHRP2 Solutions”, are now available and are in the process of being deployed to State DOTs and other organizations by FHWA and AASHTO. Renewal Overview Renewal is one of four SHRP2 focus areas, and is based on the “Get In-Get Out-Stay Out” philosophy. It addresses aging infrastructure through rapid design and construction methods that cause minimal disruptions and produce long lived facilities. Also, to be able to do this systematically, across all projects regardless of size or scope. There are 24 products total in the Renewal Focus Area. Approximately 6 – 8 new products per year are being implemented over a multi-year time frame. Calendar year 2016 will be the final year for introduction of new Renewal products. A total of $42.8 million has been budgeted for the implementation of the Renewal products. At this time, implementation activities are underway on all 24 of the products. Since each of the products are being phased in over a 3-4 year time period, implementation work has progressed further on the earlier products. For the latter projects, implementation planning activities are currently underway. Implementation Assistance The primary method that we are using to get States engaged in the use of SHRP2 products is through the Implementation Assistance Program (IAP). Through the IAP, we provide both financial and technical assistance for product implementation. Application periods, also called application rounds, are generally offered twice each year. The assistance is available at three participation levels: Proof of Concept Pilot – Gives a State an opportunity to help evaluate the readiness of the a particular product User Incentive – Available to accomplish a variety of implementation activities. Examples include conducting internal assessments, executing system process changes, and organizing peer exchanges Lead Adopter Incentive – Available to help offset costs associated with product implementation and risk mitigation. A wealth of information is available on SHRP2 website at http://www.fhwa.dot.gov/goshrp2/ Looking forward - Round 7 of the Implementation Assistance program will be open from April 1 to April 29, 2016. The will be the final round of the IAP, so State DOTs and local agencies should plan to participate and take advantage of the product offerings. This is also shaping up to be the largest product offering to date, with 13 products currently planned. More details about Round 7 and other SHRP2 information can be found online at both FHWA’s and AASHTO’s web sites.

Presentation Notes

This slide provides a snapshot of all of the Renewal products. The products are categorized within 5 key areas – Pavements, Bridges, Project Delivery, Non-Destructive Testing, and Utilities/Railroads. There is a fair amount of overlap within each category though. For example, several of the NDT products deal specifically with Pavements (R06B, R06C, R06D, and R06E), and others deal with Structures (R06A, and R06G). Similarly, R02 and R07 are primarily project delivery tools, but they addresses both Pavements and Structures. All of these products are being actively advanced for implementation at this time. Most have been made available through the Implementation Assistance Program, and many will be made available again in upcoming rounds. Much more information about all of the Renewal products, and upcoming Implementation Assistance opportunities are available at the GoSHRP2 web site.
