DOT Concrete Joint Sealing

project scope

Project Scope

The California Department of Transportation (Caltrans) is responsible for the maintenance and repair of the state’s highways and roads. In early 2023, Caltrans was faced with a problem on a number of sections of its arterial roads throughout the state.   The longitudinal concrete joints in the pavement needed sealing, due to water ingress into the subgrade and causing damage.  Additionally, the Portland Cement Concrete (PCC) pavements require sealing for two other sources of pavement distress: incompressible materials spanning concrete joints, and de-icing materials that are a sources of accelerated pavement aging.



Caltrans decided to use Concrete CamoSeal to seal the longitudinal concrete joints. Concrete CamoSeal is a high-performance joint sealant that is designed to prevent water infiltration and erosion. It is also resistant to traffic loads, thermal movement, and weathering.



The application of Concrete CamoSeal was a success. The joints were sealed effectively, and water infiltration was prevented. Caltrans is pleased with the results of the project and has since re-ordered Concrete CamoSeal for use on other projects.



Concrete CamoSeal is an effective and durable joint sealant that can be used to prevent water infiltration and erosion. It is a cost-effective solution that can help to extend the life of pavements.  Wouldn’t be great if your most cost effective pavement maintenance treatment lasted a long time?
