An increasing number of agencies, companies, organizations, institutes, and governing bodies are embracing principles of sustainability in managing their activities and conducting business. Historically, sustainability referred to environmental sustainability and simply meant using natural resources in a way that people in the future could continue to rely on their yields in the long term.
A Void Reducing Asphalt Membrane, (VRAM), project took place on August 3rd & 8th in Hennepin County, Minnesota. This was a Minnesota Department of Transportation (MnDOT) project.

Building Resilient Transportation Infrastructure Requires Investment, Innovation & Collaboration
“At the federal level, the Infrastructure Investment and Jobs Act (IIJA) has established both a formula and a discretionary program aimed at rewarding states that enhance the resiliency of transportation infrastructure and make plans for future investment.
At the federal level, the Infrastructure Investment and Jobs Act (IIJA) has established both a formula and discretionary program aimed at rewarding states that enhance the resiliency of transportation infrastructure and make plans for future investment.
As chronicled in the pages of this issue, stories of our industry’s endeavors to incorporate resiliency into transportation improvements abound. For example, building information modeling (BIM) helped replace the aging East 138th Street Bridge (known by many as the Madison Avenue Bridge) in New York City, making the city’s transportation grid more resilient. Learning from past weather events, highway engineers in Florida have constructed a 2.4-mile stretch of highway on the state’s east coast designed to be more resilient in the wake of future storms.

“The three tenants of sustainability are people (social), planet (environmental concerns), and the oft-forgotten profit. As a graduate student, I lounged one evening on my porch after a day of pounding out proctor samples in the lab, sipping on a craft beer (my millennial is showing), and reading the book ‘Cradle to Cradle’ by architect William McDonough and chemist Michael Braungart.
That book changed my career trajectory. One of my biggest takeaways was that I could do everything in the world for people and the environment; but if I didn’t make a profit, I would go out of business. That’s not sustainable.
RAP is a great example of cradle-to-cradle. Old binder is binder; old aggregate is aggregate. Asphalt pavement is used as asphalt pavement. How do we, the asphalt pavement industry, leverage sustainability (do good for our neighbors and our world) to also make a profit?”

Footnote: Reclaimed asphalt pavement (RAP) is the term given to removed and/or reprocessed pavement materials containing asphalt and aggregates. These materials are generated when asphalt pavements are removed for reconstruction, resurfacing, or to obtain access to buried utilities. When properly crushed and screened, RAP consists of high-quality, well-graded aggregates coated by asphalt cement.
We’ve all been told the importance of recycling. “Reduce, reuse, recycle” is a phrase we’ve heard all our lives. The importance of waste reduction lies in every direction. Ultimately, nobody wants to live in a high pollution environment or suffer the effects of climate change. There are economic, environmental, and equitable advantages to being a change agent for recycling initiatives.
Pavement preservation is a cost-effective and environmentally friendly way to extend the life of roadways which helps public funding go further. A pavement preservation strategy is proven to produce fewer greenhouse gas emissions, expend less energy, and give faster application times than the alternative conventional approach, in addition to being cost-effective.
Improving the resilience of infrastructure helps advance a more sustainable transportation network.

Cold Constructed Asphalt Pavement (CCAP®) is a cold mix asphalt that is created by combining aggregate and a chemically modified asphalt and mixing the two ingredients at ambient temperature. The cold mix may be stockpiled for weeks to a few months and then placed using a paver for road repair such as patching potholes or adding a new layer to low-volume roads. A chip seal is often placed over the cold mix.
Chip seals are an application of asphalt emulsion or chemically modified asphalt, followed by a layer of aggregate which is rolled and embedded into the emulsified asphalt. The process may be repeated to create a double or triple chip seal.
