Seal Coat Binder Specification

In 2012, Texas Department of Transportation (TxDOT) allocated approximately $336.68 million for preventive maintenance work throughout the state. These contracts predominantly utilize seal coats to treat roadways selected by district staff. The roadways selected to receive a seal coat treatment are determined by evaluating the current Pavement Management Information System data along with visual inspections and recommendations of maintenance supervisors and area engineers. A prioritized list of projects including corresponding project cost estimates is typically developed and compared to the preventive maintenance funding allocated to the district. This research project evaluated the success of this system to date by 1) identifying districts with chip seal projects accomplished under this system; 2) interviewing TxDOT personnel, material suppliers, and contractors with experience under this system; 3) summarizing the experience of the various parties; 4) analyzing the information; and 5) reporting the results.
