A successful seal coat is one that seals the pavement from air and water intrusion while providing the safety benefits of maintaining sufficient friction over the design life of the seal coat. Seal Coat application rate design methods are rarely used and have not been significantly updated since the early 1980s. The Texas Department of Transportation (TxDOT) typically uses experience to determine seal coat application rates. Unfortunately, the experience level is variable, and loss of experienced personnel can lead to increased problems until experience is gained. Some of these problems are flushing, bleeding, and rock loss. With over $300 million annual investment, it is imperative that seal coats are successful.
