AID‐PT: BackgroundNetwork is mostly constructed◦ Current focus on maint, rehab and reconstruct
Roadway needs are staggering◦ Almost ½ NHS is less than good condition◦ Costs to motorists approach $80B
Pavements are important part of asset!◦ 50% of federal investment
To ensure greatest return on investment ◦ Prompt implementation of pavement technologies◦ Leveraging of federal investments
AID‐PT: BackgroundRecognizing Need, Congress established◦ Accelerated Implementation and Deployment of Pavement Technologies (AIDPT) provision of MAP‐21
◦ Promote, implement, deploy, demonstrate, showcase, support and document application of innovative pavement technologies, practices, performance and benefits.
◦ Focus on changing practice rather than research
Provides funding to advance the latest and best pavement technologies through FHWA/ Industry collaborations.
AID‐PT: BackgroundINTENT: Administered and conducted in collaboration with stakeholders with proven track record ◦ of effective technology deployment on a national scale,
◦ stakeholder involvement, ◦ experience with leveraging public sector investment
AID‐PT Helps AgenciesManage pavement assets more effectively◦ Save time & money
Improve conditions of the national network◦ Save lives & contribute to economic growth
Use recycled materials and byproducts in pavement application◦ Save resources & environment
It has been very encouraging to see the AID‐PT program, established under MAP 21, rapidly advance new pavement technologies that are critical to keeping our transportation system in as good a condition as possible with available funding.

Changing Practice, Reducing Costs“Innovations like thin asphalt overlays afford the Texas DOT to stretch our limited transportation dollars…The initial construction costs of thin overlays are about 30 percent less expensive . . . [saving] $17 million in the Austin District alone.”
– Mike Arellano, TxDOT, Austin District Materials and Pavement Engineer
“The CP Tech Center workshop, and their project‐specific advice, helped save the North Carolina DOT about $8 million in pre‐overlay patching costs, including time and material.”
– Nilish Surti, NC DOT Construction Unit
“A properly designed Perpetual Pavement . . . virtually extend[s] pavement life indefinitely. . . . The Polk County project demonstrated how local agencies can pave more miles for the same money thanks to increased use of RAP.”
– John Bellizzi, City of Des Moines, Iowa, Public Works Director (retired)
Building on AID‐PT’s SuccessesThe AID‐PT program has proven itself. After only two years, its impacts have far exceeded expectations. It is providing tangible, measurable results across the nation
The next round of AID‐PT support can ensure continued success for our nation’s roadways.
The AID‐PT program is a positive example of the results that are possible when public‐ and private‐sector resources are leveraged to assist State highway agencies, and ultimately, to benefit the traveling public.
This program has really just begun…Industry is committed to program and sees this as a long‐term endeavor
We need your help to make a differenceThe AID‐PT program brings government and industry together to implement pavement technologies that impact the majority of the nation, improve infrastructure, and save money.
What can Congress Do?◦ Stabilize and Grow Revenues for the Highway Trust Fund
◦ Reauthorize MAP‐21 Before May 31, 2015◦ Reauthorize the Accelerated Implementation and Deployment of Pavement Technologies Program
