NAPA Helps Explain New Sustainability Terminology Expected to Become Commonplace in 2022

At The Heritage Group, we have been developing environmentally sustainable solutions for more than 50 years. We started Heritage Environmental Services with a Subtitle C landfill in 1970, the same year the EPA was created. Today, Heritage Environmental Services is a leader in environmental sustainability and a one-stop waste management solution spread across North America.

Sustainability is important all across The Heritage Group. Our businesses are focused on leaving the world a better place for future generations.

At Asphalt Materials (AMI), we work closely with The National Asphalt Pavement Association (NAPA). NAPA works to support, advocate, and advance the asphalt pavement industry. One of NAPA’s focus areas for 2022 is climate stewardship and how asphalt is environmentally friendly as it is America’s most recycled material. Our industry continuously explores methods and practices to contribute to a sustainable infrastructure and a healthy environment for generations to come.

As part of NAPA’s Climate Stewardship Task Force, they will be helping explain terminology that is expected to become commonplace in 2022. Look for more updates in the coming weeks. Here are a few listed below.

Carbon Footprint

Carbon footprint is an estimate of how much carbon dioxide is produced to support your lifestyle. Essentially, it measures your impact on the climate based on how much carbon dioxide you produce. Factors that contribute to your carbon footprint include your travel methods and general home energy usage. Carbon footprints can also be applied, on a larger scale, to companies, businesses, even countries. (Source: NAPA Action News.

Carbon Dioxide (CO2)

Carbon dioxide is a colorless, odorless gas produced by burning carbon and organic compounds and by respiration, what people exhale when they breathe. It is naturally present in air (about 0.03%) and is absorbed by plants in photosynthesis. Carbon dioxide is one carbon atom that is joined with two oxygen atoms.

Carbon Dioxide is Naturally Occurring

Carbon dioxide is a naturally occurring gas. When you inhale (breathe in), air enters your lungs and oxygen from the air moves from your lungs to your blood. At the same time, carbon dioxide, a waste gas, moves from your blood to the lungs and is exhaled (breathe out).

Heritage Construction & Materials

Our Heritage Construction & Materials (HC+M) family of companies have built roads, bridges, and other commercial projects across the Midwest and as far away as China. Our asphalt and aggregate supply companies produce and distribute the highest quality road construction materials and specialty minerals throughout the country.

HC+M companies are industry-leading innovators, due in large part to the problem-solving nature of our employees, our close collaboration with the Heritage Research Group , and our mutual commitment to listen to the needs of our customers.

As part of The Heritage Group, Asphalt Materials was founded in 1956 and we continue to supply high quality products and services around the United States, allowing us to excel in pavement preservation techniques and construction services.

We work closely with the Heritage Research Group team to ensure the highest quality asphalt materials and processes are brought to market. We are committed to building long term relationships and mutual trust. We are excited to tackle our industries biggest challenges, looking for new and inventive ways to create solutions that will mean better, safer and longer lasting roads.

DuPage County Illinois Finds Success Protecting Pavements

Studies have shown that longitudinal joints in pavements are often the weakest areas of a road. Typically the joints are low in density, high in voids and thus are highly permeable. These areas become conduits to air and water infiltration which leads to damage and premature pavement failure. (1)

During the 2016 construction season a new method of longitudinal joint construction was specified in Illinois. This new method is a materials approach and is referred to as VRAM(2), a Void Reducing Asphalt Membrane. Applying VRAM at the time of construction helps fill the pavement voids, thus reducing the permeability in this most critical area.

As part of their evaluation, DuPage County ensured that test cores were taken on different joint constructions, such as VRAM and joint heater. DCT, I-FIT, density, and asphalt binder grading tests were performed to compare the different joint construction methods. The report summarized that the addition of the VRAM contributes to a more durable joint by partially filling the joint and adjacent mat air voids. The joint will be much less permeable and less likely to allow water infiltration.

National Air Traffic Control Day: Recognizing Our Work at Coles County Airport

National Air Traffic Control Day was first held on July 6, 1986, on the 50th anniversary of the establishment of the air control system in the United States. According to Senate Joint Resolution 188, which designated the day, it was created to increase public awareness about the United States National Airspace System and to give people a way to “express their gratitude and respect” to “pioneers of the technology of air traffic control” and to all air traffic control personnel.

Many might wonder how National Air Traffic Control Day relates to the work we do here at AMI. The work we do expands far beyond just county roads and highways. We also have experience working with airports because just like with roads, protecting longitudinal joints is also important for airport runways! This past June, we completed a 7,300-foot J-Band project at the Coles County Airport, located near Mattoon, Illinois. The application was scheduled to be 18” wide and 1.51 lb./ft for the 2” surface mix, P401, PG64-22, N40. This was over a recently applied and tacked level binder mix.  J-Band, which is a Void Reducing Asphalt Membrane (VRAM) was measured at 280F after the distributor applied. In total, 7,124 ft and 10,330 lbs. were applied for a total yield of 1.45 lbs./ft. Images of the project can be found below. In Illinois, you may also see VRAM referred to as a Longitudinal Joint Sealant (LJS).

The air control system, created by the United States Bureau of Air Commerce, is the National Airspace System. It works to ensure adequate spacing between airplanes that are flying on routes and to prevent congestion at airports. There are more than 14,000 air traffic controllers, who together with engineers, electronics specialists, and technicians make up the National Airspace System. The system is a model for the world aviation community, is known for its safety and efficiency. Over the course of its first 50 years, the volume of air traffic in the United States expanded one hundred and eighty fold. Today, 5,000 aircraft are in the air in the country at any given moment, with millions of flights taking place each year. The country has 5.3 million square miles of domestic airspace and 24 million miles of airspace over the oceans. On National Air Traffic Control Day, we thank all those who work to keep the airways safe as part of the National Airspace System, and we work to make the system stronger.
