Midwest didn’t wait for environmental issues to become popular. We’ve been seeking the most ecologically responsible methods and safest formulations for over two decades, and still lead the industry in providing alternatives that balance superior performance with natural processes.
The environmentally positive road stabilization alternative from the innovators of soil stabilization technology.
Reduce CO2 and Unlock Federal Funding To Construct Naturalpave Roads
Naturalpave Reduces CO2 Emissions By Over 50%
A recent third-party study, conducted by the Norwegian University of Science and Technology, evaluated the Carbon Dioxide Emissions (CDE) generated during the construction of roads. The CDE's generated during the construction of NaturalPave roads were compared to those generated during the construction of a traditional unstabilized gravel road.
The study found that constructing roads with Midwest’s NaturalPave system reduced CO2 emissions by up to 53%. As part of the study, laboratory test data was used to calculate the reduction in aggregate base course thickness achieved with Midwest's NaturalPave compared to unbound gravel. The calculations found that a NaturalPave road required 50% of the gravel thickness to support the same traffic as a traditional gravel road.
By reducing the thickness of the aggregate from 20cm to 10cm as determined is possible in the study, the CO2 emission during construction greatly decreased. This is due to the reduced transportation of aggregate to the site which contributes heavily into the generated CO2 emission during construction. The study also compared the CO2 emission generated with each process at various transportation distances to understand how this impacts the overall CO2 emissions generated.

The reduction of CO2 emissions doesn’t stop after the NatualPave road is installed. Due to the hard, smooth surface of a NaturalPave road, rolling resistance is reduced - resulting in less fuel consumption for vehicles. And unlike traditional gravel roads that can require constant maintenance and annual re-graveling, NaturalPave roads virtually eliminate maintenance activities and extends the gravel life by 2-3X – further reducing CO2 emissions over the life of the road.
In 2022, the US Department of Transportation’s Federal Highway Administration created the new Carbon Reduction Program that unlocks $6.4 billion in funding for states and localities over five years. “This new program provides states and local agencies in both urban and rural areas the flexibility and funding needed to reduce emissions and build a more sustainable transportation network that will benefit all travelers,” said Deputy Federal Highway Administrator Stephanie Pollack.The Program allows the carbon reduction strategy to include projects and strategies for safe, reliable, and cost-effective options, and most specific to gravel road alternatives: to facilitate approaches to the construction of transportation assets that result in lower transportation emissions as compared to existing approaches.

Environmentally Friendly Alternative to Asphalt
In addtion to the cost savings benefits realized, Midwest's NaturalPave Road Stabilization provides an environmentally friendly alternative to traditonal paving methods such as asphalt. The process of manufacturering, installing and maintaining asphalt pavements creates considerable negative environmental impacts including: depletion of fossil fuels and minerals, contribution to global warming, human toxicity and ozone depletion.
- Traditional Paving Methods
– Product of fossil fuel and green house gas dependant mining and transportation operations
– Requires a high volume of crushed rock - a finite and limited resource
– The manufacturing and installation process produces higher volumes of greenhouse gases and emissions
– Installed surface absorbs heat
– Releases harmful and carcinogenic volatile compounds during the installation process
- NaturalPave Methods
– Eliminates the need to mine and transport aggregate by utlizing the inplace materials and existing soils
– Less equipment and emissions during the installation
– The installed surface does not absorb heat like asphalt
– Products, installation, and finished surface do not harm vegetation or human health
