4 Ways Road Construction is Going Green - Thursday, January 21, 2016

Like many others, the concrete and construction industries are looking for ways to reduce emissions and increase sustainability across the board. From certification programs to recycled materials, significant strides towards sustainability are happening all the time. In fact, the cement industry reduced energy consumption by 37.5% from 1972 to 2006, according to the Portland Cement Association.

Every project has different specifications, making the need for innovation and a variety of options absolutely essential to finding greener business methods.

The cement industry reduced energy consumption by 37.5% from 1972 to 2006, according to the Portland Cement Association. Needless to say, the efforts in this direction have been going on for a long time.

Here are four sustainable practices and trends we're seeing with road construction projects across the country.

1. Greenroads Certification

This is a whole lot of things rolled into one, but it’s a biggie for the ambitious. Greenroads Certification is road construction’s version of LEED Certification buildings. There are a series of credits that can be earned by any road project that build up toward getting the project certified.


It can turn a simple road construction project into a sustainability leader, with an eye on our future. This is a big development in the industry and an entirely voluntary program.

2. Measuring Water Use

It sounds deceptively simple. Yet, with droughts an annual problem across the country, this can be an important one.


Simply having a formal plan for managing water use on a road project can give a project credit towards a Greenroads certification. It can take a lot of water to cut soil cement. One way Angelle is managing water usage is by offering SuperSlurry, which is pre-mixed. The cement slurry can save money by not requiring an additional water supply vehicle on the job site, and can allow for stricter management of water usage.


3. Recycled Materials

Through great projects like the Recycled Materials Resource Center, we are getting more advocates of and resources for recycling materials. 94% of aggregate used annually in concrete can wind up in landfills.


Through recycling projects and the search for alternative materials, strides are being made on this front by universities and partners like The University of New Hampshire-Durham, the University of Wisconsin-Madison, and the Federal Highway Administration, who co-created the Recycled Materials Resource Center. They’re looking at solutions in everything from ready mix to architectural concrete.


4. Full Depth Reclamation

Angelle also does its part to utilize recycled materials through its use of Super Slurry in full depth reclamation road projects. Full depth reclamation is a recycling method where yesterday’s roads serve as the aggregate for tomorrow’s durable and economical new pavements. Because of its unique consistency and ability to stabilize any soil type, Super Slurry is an ideal solution for FDR. This unique combination creates an environmentally sustainable solution for roadway repairs. It also creates an entirely new application for soil cement stabilization in populated areas where traditional dry cement is not a viable option. 

By utilizing the existing road as the new base, it dramatically reduces the amount of material required to be hauled away and ultimately replaced with a new material thereby reducing CO2 emissions by up to 90% and making the entire repair a much shorter project.


Angelle continues to work toward sustainability as well, and will continue to for all of your commercial concrete and custom concrete projects.
