UPGRADE YOUR GRAVEL ROAD TO NATURALPAVE

Midwest takes a wholistic approach to road stabilization. Often times the base and surface are mistakenly viewed as independent pavement layers. Although both layers serve a unique and different fuction, their perfomance and servicabilty is very much connected to each other. For instance, a well-constructed surface course is likely to fail prematurely if the base course is not adequately constructed and/or stabilized. The same is true about a well-constructed base course with a poor surface.

Our NaturalPave Road Stabilization is strategically designed to improve the two main components of a roadway: the base and the surface. However, the NaturalPave Base Stabilization does not require surfacing and can act as its own wear course layer when additonal surface protection, traction, and wear resistance is not required.

NaturalPave Base Stabilization

The base course is the most important pavement layer and provides the structural foundation for the roadway. Its main function of the base course is to improve the load bearing strength of the road by distributing the traffic loads, resisting deformation, and facilitating drainage. Traditional construction practices involve importing and laying specific base course aggregates prior to installing the surface course. However, Midwest's NaturalPave Base Stabilization stabilizes the existing onsite aggregate, broken pavements or native soils - eliminating the need and costs associated to importing new aggregate. If installing new aggregate is desired, often the design thickness of the stabilized base layer can be dramatically reduced compared to traditional design thicknesses.

Installing Midwest’s NaturalPave Base Stabilization into the native in-situ soil or existing reworked base course creates a durable foundation that will support the most demanding traffic loads without premature surface failures resulting from insufficient base strength. This significantly reduces the required maintenance and ensures that the surface course and road remains in good functional condition for much longer.

In addtion to the strength improvements achieved, the treated material is free of dust. When exploring traditional surfacing options, this allows for stronger and more uniform adhesion of the surface course to base course, often eliminating the need for a prime coat.

Consider the benefits of NaturalPave Base Stabilization:

  • 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
  • Performance not impacted by freeze/thaw cycles
  • 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

NATURALPAVE SURFACE

The surface course layer's primary function is to provide a quality, smooth ride, and a skid-resistant surface with adequate friction and drainage. The surface course typically consists of smaller aggregate with an increased fines content to help keep the surface densely bound to resist erosion and deterioration. Often without stabilization the surface course can quickly deteriorate creating safety issues that require frequent maintenance.

Quality surface course aggregate conforming to the gradation and specification required to perform at a high level is hard to aquire in many cases. Asphalt surface courses are costly to install and require specialized maintenance throughout the pavement's life. NaturalPave Surface eliminates the need to install hard-to-find and costly surfacing materials.

Midwest's NaturalPave Surface protects the base course 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. From a cost savings perspective, NaturalPave Surface will dramatically reduce maintenance, improve the overall performance life, and prevent the loss of aggregate and fines.

Most importantly, NaturalPave Surface increases driver safety by creating a dust-free, bound surface with good skid resistance. 

Consider the benefits of NaturalPave Surface:

  • Eliminates the need to crush, transport and install surfacing materials
  • Protects the base course
  • Provides a skid resistant surface
  • Reduces maintenance activities
  • Resists surface deterioration and erosion
  • Prevents the loss of aggregate and fines from the surface
  • Increases the CBR of the surface course
  • Reduces the required surface course thickness
  • Extends the service life and preserves 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
