Abstract: The results indicate that the fuel and abrasion resistance of the E-Krete™ product exceeds that of a typical unmodified coal tar emulsion. E-Krete™ is resistant to hydraulic fluid but has been shown to soften in contact with synthetic jet turbine fluids. Use of an appropriate surface sealer will delay E-Krete™ from softening in areas where jet turbine fluids may be spilled. The abrasion resistance is approximately 8 to 10 times greater for unsealed E-Krete™ and 2 times greater for sealed E-Krete™ compared to a typical unmodified coal tar emulsion sealer. No freeze-thaw damage occurred to E-Krete™ with deicing fluid after seven freeze-thaw cycles. The laboratory data and field data both suggest that the material is durable and resistant to weathering. The field demonstrations have been successful with performance at or above expectations at all sites. However, although the performance has been rated as excellent, this is based on only 2 to 3 years of experience with these products. Field conditions are reported from observations conducted in November 2000. Several of the demonstrations were placed on severely cracked asphalt and many of those cracks have reflected through the E-Krete™ surface. No significant forms of distress that are directly related to the E-Krete™ product have been observed as of November 2000. Based on the observations at McConnell Air Force Base and MacDill Air Force Base, it appears that the E-Krete™ will soften if exposed to synthetic jet turbine lubricant spills. Overall, the E-Krete™ product would appear to be an excellent alternative to conventional coal tar fuel resistant sealer (FRS). Based on the performance of demonstration sites and inspection of other sites over 5 years old, it is estimated that the service life of E-K.rete™ will be approximately 10 years in areas with light traffic. Life cycle cost analysis indicates that the costs ofE-Krete™ based on an estimated 10 year E-KreteTh1 life and using resealing of a coal-tar surface every 3 years.
