Pavement Inspection & Design

Our Pavement Engineering and Testing encompasses all aspects of designing, building and maintaining pavement structures.  Our engineers successfully test and apply technologies that will make these pavement structures safer and more cost-effective. Our engineers have in-depth knowledge of the production and behavior of paving materials, and understand how they will deteriorate under the combined effects of traffic and the environment.

We are familiar with specifications from various agencies including state and federal highway departments, ASTM, FAA, FHWA, AASHTO, and the U.S. Army Corps of Engineers.

Single Pass Cold In Place Asphalt Recycling

With fewer funds available for public works construction, municipalities must spend tax payer dollars wisely.  Also, budget constraints in the private sector require prudent and innovative maintenance programs.

One solution is Single Pass Cold In-Place Asphalt Recycling utilizing the Wirtgen 2100 OCR cold recycling machine.

The Wirtgen 2100 OCR features a variable width vibrating screed, a milling drum equipped with automatic grade control and a liquid emulsion additive metering system. This system has an electric control unit with a programmable microprocessor that compensates for the forward speed of the machine, the milling depth and material density.

These components work together to produce a recycled pavement with the specified gradation and liquid content in a single pass, completing the rehabilitation of the roadway faster.

The 2100 also utilizes all-track steering, allowing it to easily navigate parking lots, cui-de-sacs and other areas where maximum maneuverability is required.

This operation creates a bituminous base at a specified depth without closing the road. This allows the motoring public complete access to the road, including city and safety services.

Benefits of the Wirtgen 2100 OCRand Single Pass Recycling

  • 100 percent recovery of the old roadway material investment.
  • A project cost savings of between 25 and 40 percent, when compared to traditional road surface rehabilitation.
  • Conversion of the old roadway into a base material with a much higher structural value, offering added protection of your new investment.
  • Elimination of cracking pattern in the old pavement surface.
  • Immediate use of recycled roadway with less inconvenience for motorists and shorter disruption of traffic patterns.

J-Band (Void Reducing Asphalt Membrane)

J-Band is a hot applied asphalt membrane used to extend the life of longitudinal HMA joints.  J-Band is resistant to flow and non-tracking to construction traffic within 30 minutes of application under the intended construction joint.  J-Band migrates 50-75% into the HMA void structure after rolling, thus reducing permeability at the joint.  The reduction in permeability minimizes water and air intrusion into the joint resulting in reduced cracking and stripping and improved pavement performance.


J-Band is applied using a specialized distributor with a parallel spray bar attachment. Application rates vary depending on the existing pavement type and thickness of the HMA overlay.

Physical Properties

Appearance: Black

Physical State: Viscous liquid at elevated temperatures

Spec. Gravity: 1.09

Boiling Point: >750˚F

Storage & Handling

J-Band should be stored in a heated tank with mixing capabilities at a temperature range of 285˚F to 325˚F. Storage life is up to 30 days, depending on temperatures. Specialized transport tankers may be required, depending on distances and storage times.
