Abstract:

This report presents the findings on the evaluation of Crafco Incorporated Roadsaver 903 SL Silicone Sealant and Dow Corning 890 SL Silicone Sealant. The Research Technical Panel had proposed to use the two self-leveling silicone joint sealants in test sections to seal longitudinal joints between Portland

Cement Concrete Pavements (PCCP) and Asphalt Concrete (AC) shoulders.

The SDDOT Materials Lab conducted in-house tests on both the Crafco Incorporated Roadsaver 903 SL Silicone and Dow Corning 890 SL Silicone sealants. The results of the tests were compared to the SDDOT 1998 Standard Specifications for Roads and Bridges, Section 870 Concrete Joint Sealer

Specifications as well as to each manufacturer's silicone sealant specifications. Military Specification S-8802E and ASTM Designation 5893-96 Standard Specification for Cold Applied, Single Component, Chemically Curing Silicone Joint Sealant for Portland Cement Concrete Pavements were reviewed to

determine appropriate curing and tack free times for the silicone samples.

Neighboring states were contacted to determine if they used silicone sealants to seal longitudinal joints between PCCP and AC pavements. The results of the survey, as well as recommendations from Crafco Incorporated are contained in the report. Based on this information, the researcher recommended that the SDDOT only allow the use of approved hot-pour sealants for PCCP/AC longitudinal joints.
