AASHTO TECHNOLOGY IMPLEMENTATION GROUP

TIG:

Driving Innovation for Transportation

Keith Platte, P.E.Program ManagerAAASHTO

2


What does TIG do?

Promotes Focus Technologies that are:

• market-ready• high pay-off

3


How does TIG work?

• Two Tier System– Executive Committee (top DOT

executives)– Lead State Teams

4


How does TIG work?

• Executive Committee (top DOT executives)– Solicit and Select the Technologies

(Annually - 3-4 Focus Technologies, 2-3 Additional Selected Technologies)

– Program Oversight and Management

5


How does TIG work?

• Lead State Teams– Formed for every Focus

Technologies• 4-7 State DOT Subject Matter Experts• 1-2 FHWA • 1-2 Industry

6


How does TIG work?

• Types of Technologies

– Focus Technology• Lead State Team is Formed• Dedicated budget for marketing/implementation

– Additional Selected Technologies (AST)• No Team assembled• Produces a White Paper

7


What are the current Focus Technologies?

• Self-Propelled Modular Transporters (SPMT)

• Construction Analysis Software Tools (CAST)

• Automated Machine Guidance (AMG)

• Precast Concrete Paving Slabs (PCPS)

8


What are the current Focus Technologies? (cont’d)

• Maintenance Decision Support Systems (MDSS)

• Cable Median Barriers (CMB)• Weigh in Motion (WIM)

9


Additionally Selected Technologies (AST):?

– Slope Stabilization Using Recycled Plastic Reinforcement

– Low Profile Barrier Systems– Embedded Data Collector

12


What do Lead States Teams do?

• Provide hands-on assistance • Identify prospective adopters • Reach out to other key stakeholders

14


Types of deliverables from Focus Technologies?

• Suite of Materials (with a TIG Brand)– Brochure– Presentation (PPT or Video)– Case Histories– Website

16


Tell us about Self-Propelled Modular Transporters…

• Why SPMT? Why now?– Significantly reduce traffic

congestion/impact– Open highways to traffic in minutes/hours– Improve quality and constructability– Improve work zone safety– Increase contractor and owner options

17


What are SPMT’s?

• Combination of multi-axle platforms • Operated through state-of-the-art

computer control system• Capable of pivoting 360 degrees• Lift, carry, and set very large and heavy

loads

18


How do SPMT’s work?

• motorized vehicles that move at walking speed

• carry bridge structures from offsite locations

• position them precisely into position• return area to traffic within minutes or

hours

19


What bridge operations are SPMTs used for?

• New bridge installation• Reconstruction • Move & “recycle” entire structures• Removal of old structures

20


Sample of SPMT Savings:

Mobilization cost offset by savings:

• Fewer/shorter maintenance-of-traffic setups

• No temporary-detour construction/repair of long-term detours

• Less user costs from construction-related delay and congestion

• Better performance of prefabricated structure.

Contractors reap: lower insurance premiums, more projects, less manpower and equipment rental time

21


Tell us about Automated Machine Guidance…

• Why AMG? Why now?– Links software with construction

equipment– Directs the operation of machinery– Provides a high level of precision– Improves speed and accuracy

22


AMG also means:

• Less changes, busts, reengineering and rework

• Less labor /time to produce high quality results

• Improved worker safety

• Agencies/contractors save time and money

• Better ride quality for customers

23


AMG is currently popular for:

• Grading operations

24


How does AMG work?

• Three-dimensional computer models to move materials with precision

• Info via GPS about how much to move or aggregate level

• Machine controls materials while operator drives down roadbed

25


AMG holds promise for:

• Curb placement• Paving• Trenching

26


Tell us about Construction Analysis Software Tools…

Why CAST? Why now?• CAST provides Information on construction options

that helps agencies:

– “Try before they buy”

– Minimize traffic congestion during congestion

– Maximize safe mobility

– Gather and organize data for IA and TMP, per new FHWA rule

27


Use CAST for:

• Planning• Design• Implementation

28


CAST options include:

• Traffic simulation/analysis • Traffic management• Construction scheduling/cost analysis• Combination of these options

29


CAST decision factors include:

• Analysis context• Tool category• Most appropriate tool within category

30


Tell us about Precast Concrete Paving Slabs…

Why PCPS? Why now?• Proven quality, durability and long-term performance

• Accelerate construction scheduling and sequencing

• Reduce work zone duration and size limits

• Reduce construction delays/congestion

• Economically viable

31


Types and products:

• Prestressed/Post-Tensioned Paving Panel

• Full-Depth Repair/Joint Replacement

• Uretek Precast Panel using High Density Polyurethane

• “Super-Slab™”

• Kwik Joint Coupling system

32


More Information on PCPS:

Check the PCPS Website:

– Frequently asked questions

– Sample specifications

– Background Information on the various products

33


So how does TIG pay for all this?

• Voluntary Contribution– Bill sent to the CEO/Sectaries office

around August/September timeframe• 40 States at $6000 each

34


What’s the latest?

• Announcement of new TIG technologies: Spring AASHTO Meeting

• Solicitation for New Technologies in May/June

• New Guidebook for Lead State Teams• Call for Lead State participation

35


How can we get involved?

• Be a pooled fund participant (Work with your Research Manager and Chief Engineer)

• Serve on a Lead States Team • Submit your agency’s technology
