What is AASHTO
Councils on Highways and Streets Dallas Hammit • • MASH Implementation Reauthorization (105 white papers) – – – • Increased Funding Increased Flexibility of Funding Formula based Funding Buy America State Match Performance Management Emergency Relief Program Cooperative and Automated Transportation Technologies Operations (TSMO) Adoption PROWAG (Public Right of Way Accessibility Guidelines Resilience of the System
Councils on Highways and Streets Dallas Hammit • State Round Table – – – – Litter campaigns (Storm Water) Cost increases and delays due to Buy America 3 D design Getting Contractor input without jeopardizing bidding Improving the safety culture State’s role in building and operating electric charging stations Small-cell wireless technologies within ROW Use of drones or UAS (Unmanned Aerial Systems by DOT’s • AASHTO TRAC Bridge Challenge •
Council on Active Transportation Greg Byres • Safety and the incorporation of facilities within the roadway system. The majority of examples and ideas were for urbanized environments, and not much on rural routes. • Examples of multi-path projects were presented with an emphasis on community. The majorities of the projects presented were generally funded through local taxes and were politically driven. The Council, as a whole, was in favor of pushing these types of projects. • ADA and impacts for active transportation were discussed, with a recommendation to have AASHTO adopt PROWAG as the standard for ADA implementation. •
Committee on Construction Dallas Hammit and Bill Fay • • Workforce – Who is the new DOT (Work Force) – Diversity – Maintaining Workforce Safety – Workforce – Night Time Work Zone – Communication work zones – Blue and Red lights vs Amber Training – PE Training – AASHTO Training Tc 3 Environmental – Listed Species
Committee on Construction • MASH – Temp Signs – Barrier • Concrete Strength • Re-bar Strength • • • Dallas Hammit and Bill Fay Guide Book for CMGC (CMAR) & Progressive Design Build 3 D modeling / plans – Tools for inspections – Documentation – Pay items – Inspection methods E-construction – Storage of data/records Grinding pavements – what does it do to pavement life AASHTO Construction Manual
Committee on Design Steve Boschen • Flexible Design Workshop Management of Risk and Liability Maximize Value and Return on investment Multi-disciplinary decision making process Identifying the Project Specific needs and consideration of options to use and improve existing transportation system. Encourage early alternate design investigation SMARTSCALE Model – Liability, Accountability, Roadway PBPD - Use of Highway Safety Manual, Documentation. – – • PROWAG (Public Rights-of-Way Advisory Committee) – US Access Board Status - not yet adopted, but encouraged as best practice by FHWA and AASHTO. – New Construction is expected to meet the highest level of accessibility (to the most practical extent possible). – AASHTO is proposing to congress to adopt PROWAG.
Committee on Design Steve Boschen • Green Book Errata Sheet – COD Committee on Geometric Design - Working on development of Errata Sheet for recently published 7 th Edition (2018) of Green Book MASH Update – • – – • FHWA ceased issuing eligibility letters for devices To Date – 3 year effort to find testing facilities Sunset date is still December 31, 2019 for non MASH-compliant devices Reimbursement of NCHRP-350 compliant devices by FHWA is desired if “MASHcompliant” device is not available or tested for needs of individual states 2 D Plans to 3 D Model delivery – Technical committee on electronic engineering standards (TCEES) is currently investigating the IFC Road & Bridge Project thru building Smart International for a common 3 -D model schema.
Committee on Materials and Pavement Jesus Sandoval • UHPC (ULtra High Performance Concrete) – 17 k PSI – The Cement Concrete Reference Laboratory (CCRL) offers inspections in accordance with ASTM C 1856 • Fly Ash shortage – Raw or Calcined Natural Pozzolan are some new alternatives being proposed for SCMs (Supplementary Cementitious Materials) by DOTs and AASHTO to address shortage of Fly Ash • Hamburg Test – Montana DOT is currently using Hamburg test for QA to determine rutting and stripping susceptibility of asphalt mixes. (ADOT uses Hamburg for information only currently) Good No Good
Committee on Bridges and Structures David Benton • • • NCHRP 20 -07 Task 410 "Load rating for FAST Emergency Vehicles EV 2 and EV 3" was published and it may be a good reference. Drone can be used as supplement tools to provide info but not for inspection. Critical Finding for bridge and tunnel will be focus on report / timeline / database Load posting set for 30 days starts with Load rating completed (notified to the poster). It is under state control to make sure it will be posted in 30 days. State can withhold funding if the poster doesn't comply or use state police to enforce it. 10/1/19 is official effective date MASH to replace NCHRT 350
Committee on TSMO Brent Cain Development of a Transportation Operations Manual ü Variable speed limits and queue warnings ü Ramp metering ü ICM facilities / modes / advisories ü Planned special events ü Emergency transportation operations ü Work zone traffic management ü Traveler information (pre-trip, enroute, 511, DMS) ü Advisories (weather, safety, fog, rollover) ü Incident management
Committee on Traffic Maysa Hanna • • Increase in the gas price to handle preservation. Smart Lane, use of shoulder during peak hours 6 -9 am and 3 -6 pm FHWA update: – Pavement Marking Retroreflectivity on path to the Final rule making. – Horizontal Curve Warring Sign- compliance date will be addressed in the next NPRM. – 3 D Crosswalk – Colored Pavement for HWY Rail crossing is not under consideration. – Red colored pavement for transit lane, draft IA is under review – MUTCD new edition, NPA likely to come out later this year Speed limit: – Currently the practice is to use the 85 th percentile. According to NCHRP 17 -76 there is a recommendation to use USLIMITs 2 which will result in lower speed limit as they use the 50 th percentile.
Committee on Traffic Maysa Hanna • • Using Automated Speed Enforcement. Local Municipalities are not following MUTCD Noise complaints about the sinusoidal rumple stripes Increase of crashes after the approval of the recreational marijuana in Illinois DOT's are moving toward wider striping as a preparation of the CV/AV. Use of temporary rumple stripes in 70 mph FWYs. FHWA working with NHTSA on the type of messages DOTs can use on DMSs.
Committee on Environment Paul O’Brien • One Federal Decision (Sec. 1301) – Major infrastructure projects – Multiple federal approvals – Reasonable availability of funds – EIS- but project sponsor can request for EAs – One EIS for all federal agencies • Climate Change Resilience – Funding • Wildlife Crossings • Storm water
Committee on Planning Greg Byres Reauthorization of Transportation Bill (Top 5 issues) • Maintain existing balance of authority between DOT, MPO, COG • Fiscal constraint related to NEPA - allows completion of the NEPA process regardless of whether the project or phase is included in a fiscally constrained STIP or TIP • Do not increase burdens on planning but rather look for areas to reduce in the area of Performance Measures and Management • Increase projects eligible for CMAQ funding • Streamline and simplify the development and updating of the multitude of transportation plan documents currently required by states
Committee on Planning Greg Byres FHWA • Reported they were unsuccessful at eliminating 1997 conformity regulations. Now trying to eliminate 2008 regulations. Currently working under 2015 regulations. • Partnering with AASHTO Committee on Transportation Systems and Operations to study Freight Size and Weight issues • Working on Work Zone Standard Specifications
