AASHTOTECHNOLOGY IMPLEMENTATION GROUP 12 What do Lead States Teams do? Provide hands-on assistance Identify prospective adopters Reach out to other key stakeholders

AASHTOTECHNOLOGY IMPLEMENTATION GROUP 13 What else? Develop guidance Suggest technology enhancements Consult on information tools Serve as liaison

AASHTOTECHNOLOGY IMPLEMENTATION GROUP 14 Types of deliverables from Focus Technologies? Suite of Materials (with a TIG Brand) –Brochure –Presentation (PPT or Video) –Case Histories –Website

AASHTOTECHNOLOGY IMPLEMENTATION GROUP 15 Whats on the website? Resource Center for all Focus Technologies Suite of resources for each technology Fact Sheets on each AST

AASHTOTECHNOLOGY IMPLEMENTATION GROUP 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

AASHTOTECHNOLOGY IMPLEMENTATION GROUP 17 What are SPMTs? 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

AASHTOTECHNOLOGY IMPLEMENTATION GROUP 18 How do SPMTs 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

AASHTOTECHNOLOGY IMPLEMENTATION GROUP 19 What bridge operations are SPMTs used for? New bridge installation Reconstruction Move & recycle entire structures Removal of old structures

AASHTOTECHNOLOGY IMPLEMENTATION GROUP 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

AASHTOTECHNOLOGY IMPLEMENTATION GROUP 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

AASHTOTECHNOLOGY IMPLEMENTATION GROUP 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

AASHTOTECHNOLOGY IMPLEMENTATION GROUP 23 AMG is currently popular for: Grading operations

AASHTOTECHNOLOGY IMPLEMENTATION GROUP 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

AASHTOTECHNOLOGY IMPLEMENTATION GROUP 25 AMG holds promise for: Curb placement Paving Trenching

AASHTOTECHNOLOGY IMPLEMENTATION GROUP 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

AASHTOTECHNOLOGY IMPLEMENTATION GROUP 27 Use CAST for: Planning Design Implementation

AASHTOTECHNOLOGY IMPLEMENTATION GROUP 28 CAST options include: Traffic simulation/analysis Traffic management Construction scheduling/cost analysis Combination of these options

AASHTOTECHNOLOGY IMPLEMENTATION GROUP 29 CAST decision factors include: Analysis context Tool category Most appropriate tool within category

AASHTOTECHNOLOGY IMPLEMENTATION GROUP 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

AASHTOTECHNOLOGY IMPLEMENTATION GROUP 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

AASHTOTECHNOLOGY IMPLEMENTATION GROUP 32 More Information on PCPS: Check the PCPS Website: –Frequently asked questions –Sample specifications –Background Information on the various products

AASHTOTECHNOLOGY IMPLEMENTATION GROUP 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

AASHTOTECHNOLOGY IMPLEMENTATION GROUP 34 Whats 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

AASHTOTECHNOLOGY IMPLEMENTATION GROUP 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 agencys technology
