The strength of asphalt roads, while saving up to 70% of the cost.

The environmentally-positive alternative for semi-permanent unpaved roads, from the leading innovators in soil stabilization.

The NaturalPave® System Base

The NaturalPave® stabilized base and a selected surface course is designed and installed to hold up to the most extreme traffic demands while maintaining a long service life. It is created by incorporating one of Midwest’s patented, environmentally friendly products into the existing soil or aggregate to create a strong, high performance base using the in-place material. The base is then profiled, compacted and allowed to cure prior to installing the surface course.

After a short cure time the surface course, specifically selected for each project, is installed on top of the NaturalPave stabilized base. A variety of surface course options are available based on the traffic, desired look/aesthetics, performance/longevity and environmental considerations, among other things. Use the chart below to help determine the best performing surface course for your specific project:

The Case for a Base

The economic, health, livability and tourism benefits of connecting communities has long been documented. Hard surface roads, when constructed or reinforced correctly, yield the same benefits of concrete/paved roads. All-weather, resilient hard surface roads reduce travel time, crash likelihood, fuel use and vehicle operating expenses. They also nearly eliminate fugitive dust particles, dust pollution and severe weather washouts. Collectively, hard surfaced roads enhance community experience, qualify of life and commerce.

The benefit of hard surface roads is obvious. What may be harder to quantify is the need for a stabilized sub-base and base to ensure longevity of the surface course material. Tests show how roadbed soil properties influence and positively correlate to road surface condition. Numerous studies estimate hard surfaced roads reduce rolling resistance by approximately two-thirds to comparable gravel and dirt surfaced roads. The US Department of Energy finds light-duty vehicles experience 1-2 percent increase in fuel economy for every 10 percent decrease in rolling resistance!

It really is a matter of common sense. The surface course actually lends little to no structural support in hard surfacing. It's all about that base!

Benefits of a NaturalPave Base

Installing Midwest’s NaturalPave solution into the native in-situ soil or existing reworked base course creates a durable foundation that will support traffic loading without rutting, potholing or washboarding. Stabilizing the base reduces premature failure and ensures that the surface course and road remains in good functional condition for much longer. Also, the NaturalPave treated material is free of dust, allowing for stronger and more uniform adhesion of the surface course to base course, often eliminating the need for a prime coat.

The surface course protects the NaturalPave stabilized base by preventing surface deterioration such as erosion and raveling in addition to stopping harmful moisture from penetrating into and weakening the base. This reduction of moisture penetration greatly extends the performance life of the base material, especially in areas prone to freeze-thaw cycles. The surface increases driver safety by creating a dust-free, bound surface with good skid resistance. Consider the benefits of the NaturalPave System:

  • Eliminates the need to crush, transport and install base aggregate
  • Eliminates the need to install a sub-base
  • Eliminates subgrade preparation and improvement
  • Supports the most extreme traffic demands
  • Increases the CBR on the base
  • Reduces the required surface course thickness
  • Extends the service life and preserve the road’s infrastructure longer than conventional methods
  • Reduces equipment, labor and the overall cost of the road
  • Can be installed in a wider range of temperatures compared to conventional methods
  • Eliminates the need to wash aggregate as required with conventional methods
