A rural roadway in Washington County, Nebraska was suffering from severe alkali-silica reactivity (ASR) caused by swelling and cracking due to the reaction of the highly alkaline cement paste and the non-crystalline silica when exposed to moisture.
A new layer of pavement needed to be placed over the existing road, and the project engineer wanted a long-term and cost effective solution. REFLECTEX® Rapid Install was used as an interlayer for the unbonded concrete overlay. REFLECTEX has the ability to lower surface temperatures during applications which reduces the overall stress on the concrete pavement causing less potential for cracking.
The interlayers solar reflective properties reduce surface temperature by up to 50°F, eliminating the need to cool the surface with water. By replacing the traditional asphalt interlayer, REFLECTEX Rapid Install significantly reduces installation time and cos and allows for fewer construction delays and traffic disruptions.
The geotextile was installed over seven miles of roadway using the ProGrip™, an adhesive that replaces the traditional nail down installation method. Using the adhesive allows for a quicker and more efficient installation, and prevents the fabric from flapping in the wind as it is being installed. It also reduces the cost of labor and materials by up to 30%.
