Sheboygan County Wisconsin finds Success with VRAM

Used since 2002 and now across 19 states, J-Band has a proven track record of delivering longer road life, while also offering an impressive return on investment. Asphalt Material’s J-Band product is a void reducing asphalt membrane (VRAM).

This particular project took place in June of 2021 in eastern Wisconsin. The 5.5 mile project runs from South I-57 to North 6th Street. The J-Band application began early in the morning ~3.5 miles west of North 6th Street and went to South I-57. The ambient temperature was 55°F and the existing pavement was 60°F. A straight and consistent line of VRAM was applied throughout the project. Pro-Tack also applied VRAM at the east end of the project. As with many of our projects, an average width of 18″ of VRAM was applied for this project.

Depending on the specifications in each state, there may be an upper limit on temperature. In addition, width and application rates are also specified. Measures should be taken in all cases to ensure compliance with specifications.

Photos from the project can be viewed below.

In every state except Illinois, the product is specified as VRAM or Void Reducing Asphalt Membrane. However, in Illinois the product is specified as LJS or Longitudinal Joint Sealant. The VRAM product from Asphalt Materials is called J-Band and was created in the labs of The Heritage Research Group.
