2287 Evaluation of the Expected Life and Recoating of Silane Water Repellant Treatments on Bridge Decks

项目名称：	2287 Evaluation of the Expected Life and Recoating of Silane Water Repellant Treatments on Bridge Decks
摘要：	Field evaluations funded by an Oklahoma Department of Transportation (ODOT) task order to evaluate the effectiveness of silane coatings on bridge decks, shows that the silane is not consistently penetrating to the target depth. Further, this material is not resisting water absorption as outlined in the ODOT specifications. Based on discussions with ODOT Materials Division Engineers, the field testing is showing that one in three bridges are failing these tests. This suggests that these coatings are not effective and this puts the long term performance of the bridge in question. While some results have been obtained with a limited number of bridges, more work is needed to investigate a larger number of bridges and evaluate the current ODOT specification. This research is timely and will assist ODOT in making sound investments in the long term performance of Oklahoma’s bridges. As a result of this research a new specification for ODOT structures will be developed. The results of this research have the potential to greatly extend the service life of bridges and therefore save the state of Oklahoma millions of dollars.
