Revitalizing Sustainability: Asphalt Materials and US Aggregates Unite in Pallet Reusing Initiative 

Heritage Construction + Materials companies Asphalt Materials, Inc. (AMI) and US Aggregates have joined together to build a program that finds new ways to reuse AMI’s pallets at US Aggregates’ locations.  

This initiative keeps AMI from recycling their pallets through a third-party vendor, as well as from being discarded. It also aids in increasing efficiency amongst US Aggregates since the pallets will be received through an internal company.

The Role of Pavement Preservation Enhancing the Sustainability of Road Infrastructure

Pavement preservation is a cost-effective and environmentally friendly way to extend the life of your roadways and make public funding go further. A well-implemented pavement preservation approach achieves maximum efficiency by increasing the average condition of your pavement while decreasing your average spending per square yard. Pavement preservation treatments are known for their ability to ensure quality with minimal effect on your budget and the environment.

Pavement preservation is the core of our AMISEAL™ product line, including micro-surfacing, chip seal, scrub seal, slurry seal, cape seal, and more.

HRG Spotlight: Cold in Place Recycling Technology Delivers Morgan County Residents a Rehabilitated Road

During 2022, County Engineer Tony Hinkle reached out to Heritage Research Group (HRG), to have Waverly Park Road in Morgan County, Indiana, be sampled for a potential recycling project. The results from pavement sampling determined that the road was a candidate for a 4-inch Cold In-place Recycling (CIR) treatment. Based on the report’s recommendations, Hinkle made the decision to move forward with the CIR treatment to repair and preserve the pavement.

Reclaiming Resources through Cold in Place Recycling

Over the years, asphalt has become the most popular choice when it comes to selecting environmentally friendly pavements. To take it one step further, cold mix pavement layers have been developed to create even more sustainable products for road construction. Cold recycling techniques are methods that not only avoid the application of heat but reuse aged asphalt pavements already within the current infrastructure. This technique used helps treat raveling, potholes, skid resistance, rutting, block cracking, and so much more.  

Cold recycling includes two subcategories, cold in place recycling (CIR) and cold central plant recycling (CCPR). In this article we will highlight a successful CIR project in Jefferson County, Indiana.

Asphalt Magazine: A Complete Approach to Pavement Sustainability

Pavement sustainability continues to be one of the most crucial areas of research in the asphalt industry. While it is common to understand sustainability in a purely environmental context, truly sustainable products and innovations also have positive economic and social implications. 

Below, industry sustainability thought leader and Sustainability Engineer at the Asphalt Institute, Dr. Chait Bhat, details the appropriate scope for comparing Environmental Product Declarations (EPDs) per the International Organization for Standardization (ISO) standards language in Asphalt Magazine. His article follows a previous article from Dr. Mark Buncher covering the appropriateness of comparing material EPDs.

MnDOT finds PMBs Extend Road Service Life by Six Years

Many highway agencies recognize the benefits of using modified asphalts to reduce pavement distress and increase service life. A recent study from the Minnesota Department of Transportation (MnDOT) found that asphalt pavements with polymer-modified binders (PMBs) perform better than pavements with unmodified asphalt binders. They also found that modified binders are more cost-effective, even for local low-volume roads. While pavements with PMBs may cost more initially, performance is improved in the long run.

AMI supplies high-quality materials for CCAP® in Morgan County, Indiana

Agencies are seeking cost-effective and sustainable solutions to make roads last longer. This is why the Heritage Research Group (HRG), Asphalt Materials Inc. (AMI), Milestone Contractors, and US Aggregates are all working together in a One HC+M project to figure out how to make the strongest, most sustainable, and cost-efficient asphalt mix in the Midwest region. One solution the team has found that is not only cost efficient, but sustainable and durable, is Cold-Construction Asphalt Pavement (CCAP®).

AMIGUARD™ RPE Helping Create Longer Lasting, Safer Roads in Monroe County

What is RPE?

It is important to plan ahead when considering pavement protection and preservation techniques. Proactive pavement protection is an infrastructure investment, but it can also help ensure safety for drivers. One important aspect of pavement preservation is to reduce air voids. When air voids are high, permeability is high, which adversely affects pavement life. This is why using a Rapid Penetrating Emulsion (RPE) soon after pavement construction can be a wise investment.

HRG Spotlight: Building a More Sustainable Business With CIR Tech

In August of 2022, a project took place in Martinsville, IN with our Cold-In-Place Recycling (CIR) technology.

CIR is a cost-effective and sustainable method of constructing a recycled asphalt-bound layer that reduces trucking and construction time and saves natural resources.  CIR is part of our AMICYCLE™ product portfolio, which also includes FDR (Full Depth Reclamation) and CCPR (Cold Central Plant Recycling).
