Effective Funding Strategy
James Thomas, from Salem City public works, gives insight into his city’s strategy for preserving residential subdivisions.
After Salem’s first HA5 High Density Mineral Bond installation about seven years ago they tried using seal coats (polymer mastic sealers) for a while. However, their seal coat application in 2017 had essentially disappeared after only one year. Despite a close relationship with their local seal coat company, they were so disappointed with performance, the city decided to switch to a longer lasting, more effective High Density Mineral Bond installation. Their experience with a seven-yr. old HA5 installation looking better than their seal coats applications after only two years certainly helped as part of their decision making.
In fact, some of the HA5 roads you see in this video had seal coat installed just last year, but were no longer protecting the asphalt binder.
“I’ve been here for 11 years. Took over the department about five and a half, six years ago. We’ve got some good residents here. They really care about the city.”
Assessing 7-Year Old HA5 Installations
“To assess the HA5 we had put down seven years ago, it performed very well, very well.”
“We’ve had seal coats that have come in and in two years they look worse than the HA5 does in seven.”
“Some of the challenges of being in public works are finding the money to keep the roads where we need to keep them and spending the money right and getting a program down. Hopefully at the end of the day we’re doing the right thing. “
