Pooled fund research
Through the national Transportation
Pooled Fund research program, WisDOT is able to pool our money
with other states to fund larger research projects of common
interest.
Research is pleased to fund the
following 15 new pooled fund projects nominated by department staff
in FFY 2010. WisDOT's total contribution for these projects is
$310,000.
- Support
of the Motorcycle Crash Causation Study - Solicitation 1221
Researchers are investigating the causes of motorcycle crashes
that will enable the development of countermeasures that can be
effective in reducing these crashes.
- Characterization
of Drainage Layer Properties for MEPDG - Solicitation 1225
This study will develop methods to characterize the elastic
modulus and strength of drainage layers for MEPDG, perform
analysis of the stability and failure of the drainage layer in
the pavement structure, and develop specifications for required
minimum porosity for effective drainage.
- Investigation
of Jointed Plain Concrete Pavement Deterioration at Joints and
the Potential Contribution of Deicing Chemicals - Solicitation
1227
This study will investigate the causes of anomalous joint
deterioration in concrete to determine if deicing chemicals
contribute to this deterioration and will develop estimates of
service reduction and life cycle costs.
- Validation
and Implementation of Hot-Poured Crack Sealant - Solicitation
1233
Researchers will validate and implement the recently developed
Performance-Based Guidelines for the Selection of Hot-Poured
Crack Sealants from study #TPF-5(045)
through a comprehensive field study.
- The
Effects of Implements of Husbandry "Farm Equipment" on
Pavement Performance (MnROAD Study) - TPF-5(148)
Over the past few decades, there has been a shift to the use of
larger and heavier farm equipment. The objectives of this study
are to determine the pavement response under various types of
agricultural equipment and to compare this response to that
under a typical 5-axle semi tractor-trailer.
- Optimal
Timing of Preventive Maintenance for Addressing Environmental
Aging in HMA Pavements (MnROAD Study) - TPF-5(153)
The goal of this study is to determine the proper timing of
preventive maintenance treatments in order to optimize life
cycle costs and pavement performance. Environmental aging of the
asphalt binder in the underlying pavement is not well
understood, and this project will seek to better understand the
aging mechanism and how it can be reduced through pavement
preservation.
- Fish
Passage in Large Culverts with Low Flows - TPF-5(164)
This pooled fund study will develop more information about the
hydraulics of low flows in large culverts, which will allow for
modification of culvert design methods so that fish passage is
also achieved.
- Investigation
of Curved Girder Bridges with Integral Abutments - TPF-5(169)
Nationally there is concern regarding the design, fabrication,
and erection of horizontally curved steel girder bridges due to
unpredicted girder displacements, fit-up, and locked-in
stresses. The long-term objective of this effort is to establish
guidelines for the use of integral abutments with curved girder
bridges focusing on the monitoring and evaluation of constructed
bridges.
- Mobile
Source Air Toxics (MSAT) From Major Highways - TPF-5(170)
Researchers will study the concentration, physical behavior and
dispersion of mobile source air toxics emissions.
- An
analytical review of child mobility assessments for school site
programs - TPF-5(172)
This study supports state-level management of the Federal Safe
Routes to School Program, which addresses concerns related to
higher numbers of children being driven to school. Issues
include worsening traffic congestion, an increase in obesity
among children and respiratory diseases related to poor air
quality.
- Improving
the Foundation Layers for Concrete Pavements - TPF-5(183)
The objective of this research is to improve the construction
methods, economic analysis and selection of materials, in-situ
testing and evaluation, and development of performance-related
specifications for pavement foundations.
- HY-8
Culvert Analysis Program - Phase Three of Development Efforts -
TPF-5(202)
The HY-8 is a computerized implementation of FHWA culvert
hydraulic approaches and protocols. This third phase of the
study will develop further enhancements to the software.
- Performance
of Recycled Asphalt Shingles in Hot Mix Asphalt - TPF-5(213)
The use of recycled asphalt shingles in HMA applications has
grown over the last 10 years, but there is interest in the use
of tear-off RAS in HMA. The primary goal of this study is to
address quality assurance concerns related to tear-off RAS,
conduct demonstration projects to determine its behavior in the
field and to create a database on the performance of RAS.
- Transportation
Engineering and Road Research Alliance - TPF-5(215)
The Transportation Engineering and Road Research Alliance is a
unique alliance of government, industry and academic partners.
The goal of the alliance is to develop, sustain, and communicate
research results on pavement, materials, and related
transportation engineering challenges, including issues related
to cold climates.
- Accommodating
Oversize/Overweight Vehicles at Roundabouts - TPF-5(220)
This project will compile current practice and research related
to the effects that oversize/overweight vehicles have on
roundabout location, design and accommodation and to fill in
information gaps with respect to roundabout design and
operations for these classes of vehicles.
In addition, Research is
continuing funding in 2010 for the following 22 pooled fund projects
that WisDOT already supports, totaling $509,436.
Request funding for a project
Every spring, WisDOT Research asks staff to nominate pooled fund
projects
that WisDOT should help fund. DOT bureau directors rank the
nominations and division administrators make the final project
selection based on these rankings and the funding available. Contact
us anytime at research@dot.state.wi.us
or
(608) 267-6977 for more information.
