Geotechnical Services - Cold Weather FDR

The engineering properties of Full Depth Reclamation (FDR)-Cement highly depend on the curing environment, especially the ambient temperature. Thus, the construction of cementitiously stabilized material (CSM) is restricted in the winter by many federal and state agencies. This restriction not only shortens the CSM construction season by several months, but also increases the future infrastructure maintenance cost and influence of the productivity of cement industry. Stahl Sheaffer's cold-weather soil stabilization with cement is implemented by the inclusion of chemical additives. These additives have been widely and successfully used to reduce concrete’s freezing point and accelerate its strength development in cold weather. 

Proven to Work

• Stahl Sheaffer's Geotechnical Manager, Dr. Jingan Wang, presented the findings in Washington, DC at the 96th Annual Transportation Research Board Meeting in January of 2017.
• ​Stahl Sheaffer successfully applied the findings in field, on Roane CR 8 in West Virginia in December of 2017.

Cost Effective

• By immediately repairing early-age distress of the pavement our clients avoid the large fees associated with extreme damage done to the roadway throughout the winter season.

Longer Construction Seasons

• Unlike traditional FDR, Cold Weather FDR makes it possible for the construction of roadway reclamation projects with cement stabilization in cold  weather.
