Using compost containing source separated organic material to reduce runoff at MnDOT sites

Minnesota Statute 115A.551 calls for reaching a 50% recycling rate in the metro area and 35% in greater Minnesota. In the Twin Cities Metro Area, organics recovery is currently between 3 and 6%, with a goal of 9-15% by 2030. Source separated organic material is separated from other wastes at the source, rather than at mixed municipal solid waste transfer stations. Source separated organic material is generally transferred ...more »

Why is this a priority and what are the benefits for the State/County/City? :

MnDOT could realize cost savings, acquiring SSOC directly from compost facility operators. Compost has been shown to be more effective than traditional BMPs such as hydroseed in soil stabilization, runoff/solids/nutrients/metals loading, and vegetation establishment. Furthermore, composting presents a closed loop process, which helps actualize MnDOT’s goals of becoming more sustainable.

Vegetation management practices to increase and enhance roadside pollinator and wildlife habitat

Migratory pollinator species such as Monarch butterflies and other wildlife are at risk due to the loss of native habitats from increasing development, intensive agricultural practices, and greater use of pesticides. Roadside habitats, in particular, have grown in importance, especially as migratory corridors and places that aid in species dispersal and mixing. We’d like to identify cost-effective roadside vegetation ...more »

Salt applications and alternatives for snow and ice control by local agencies

Road salt, which is especially effective for controlling snow and ice, has been identified as a pollutant that kills roadside vegetation and contaminates the water in nearby ponds, lakes, and streams. The challenge has been to find ways to reduce salt use without compromising road safety. Fortunately, there are a number of options available, though finding and implementing the best ones can be difficult, especially for ...more »

Low-Cost Portable Device for Welding Quality Monitoring

Welding is commonly used for connecting metal components in these bridges during fabrication and/or construction. Welding processes require high heating input while various factors, such as shrinkage of weld/parent metal or overheating of joint, vulnerably lead to cracks and other defects on the surface. These defects not only could result in severe cracks and corrosion, but also may ultimately lead to malfunction and ...more »

Synthesis regarding performance of slipformed barriers and parapets

MnDOT has allowed contractors to use the slipform method of barrier and parapet construction for many years with seemingly good long performance. However, some other surrounding states prohibit the use of slipformed barriers and parapets due to some performance issues, such as local cracks. Water accumulated inside the cracks can cause potential chloride corrosion to the barrier reinforcement. There is also a concern ...more »

Why is this a priority and what are the benefits for the State/County/City? :

Barriers and parapets are typically replaced at the same time as the replacement of bridge deck. Premature cracking and failure of the barriers and parapets may require their replacement before the replacement of bridge deck, which incurs additional cost. In addition, barriers and parapets are a critical part of roadway safety. Damaged barriers and parapets can cause safety issue. This study can eliminate potential problems and improve the long-term performance of slipformed barriers and parapets in Minnesota. It has several benefits, including cost savings, increased safety and durability of these structures.

Service Life and Performance Assessment of Bridge Decks with Corrosion-Resistant Reinforcement

MnDOT is in the initial phases of designing and constructing a pair of side-by-side bridges on I-35, one with GFRP and the other with conventional steel deck reinforcement. Because these two bridges will be exposed to the same environmental conditions, very similar traffic, and will be constructed within the same timeframe, a unique opportunity exists to identify and evaluate differences in performance between them. Thus, ...more »

Idea Champion - Who at MnDOT/LRRB? : Paul Rowekamp

Why is this a priority and what are the benefits for the State/County/City? :

Degradation of bridge decks is mainly due to the corrosion of steel reinforcing bars embedded in the deck concrete. Considering the significant time and labor investment needed to repair or replace bridge decks prior to the end of their design service life, the outcome of this project is expected to be an important step forward to implement non-conventional, corrosion-resistant reinforcement, which will improve the durability and performance of bridges, while reducing direct maintenance costs. This will also minimize the indirect costs originated from bridge closure, disruption in traffic, and impact on surrounding environment.

Spatial Analysis of Agriculture Supply Chain to Assess Transportation Impacts

Efficient agriculture movement is critical to Minnesota’s economic health. In the past two decades, the agriculture supply chain experienced a number of market, technological, and policy innovations that have directly influenced the way producers and wholesalers navigate their local freight networks. With producers’ reliance on rural and urban roadways projected to grow, so too are concerns for accelerated pavement degradation, ...more »

Why is this a priority and what are the benefits for the State/County/City? :

As rural and urban roads assume a more exaggerated responsibility for connecting agricultural products to the market place, local freight planners are increasingly seeking informed, innovative solutions to address the growing industry’s transportation needs.

Outcomes of this study can inform MnDOT district and strategic freight network investments. Specific potential benefits include:

-identification of trends in specific districts of the state, that can inform local decision making, such as roadway improvement priorities

-identification of statewide trends, that can inform strategic freight investments

-provision of maps than can be used to facilitate a broader understanding of agriculture supply chain and transportation implications, including among the public and policy makers.
