Need a fast answer? Try our tack coat calculator Modifications to the Application Rate Each situation can be different, based on the circumstanc In general, a tight or dense surface requires less tack coat than an open textured or graveled surface An extreme example would be a milled road surface.

Current Projects

This study aims to evaluate the effectiveness of tack coats used by ODOT with respect to tack coat type and application rate, pavement surface conditions, moisture-induced damage and temperature Laboratory-compacted samples and field cores from selected projects are being tested selectively to evaluate the tack coat performance.

Category:408 Prime Coat

If the prime coat is too light, it will have a light brown color and will be absorbed quickly and will not sufficiently penetrate into the base The prime coat must be uniformly applied to the base course at the rate specified in the contract The application rate may need to be adjusted in the field depending on the nature of the base course.

Spec Notes

What is the Difference Between a Prime Coat and Tack Coat?

When choosing a prime coat and tack coat, it is vital to understand the functions of each of these elements, as well as their limitations With a good prime coat and tack coat, you can prepare your substrate for virtually any type of application, and be confident that the resulting floor, wall, or ceiling is strong and durable for years to come.

Pavement Manual: Pavement Surface Preparation

Tack coat application should result in a thin, uniform coating of tack coat material covering approximately 90% of the pavement surface (Flexible Pavements of Ohio, 2001) To achieve this result, application rate will vary based on the condition of the pavement receiving the tack coat.
