Holbrook Asphalt Company’s Post

Have you ever wondered how HA5 High Density Mineral Bond performs against other surface treatments? In 2020 a city we work with decided to run a test between HA5 High Density Mineral Bond and a premium seal coat. The city's team selected a suitable street for the test and applied the seal coat product and HA5 within two weeks of each other in similar conditions. You can see below that immediately after the application, the seal coat actually has a deeper black appearance and looks slightly better than the HA5. However, the real question is how has each treatment performed over time and which ultimately provided the most value. Continue scrolling through the images, and you can see them for yourself. After the initial, the seal coat arguably looked better. But looks aren't everything. 4 years later we revisited the project to see how the HA5 and the premium seal coat held up. We discovered that the seal coat was virtually gone while the HA5 is still there, continuing to provide protection and cost savings for the underlying pavements even after 4 years. #pavementpreservation #publicworks #infrastructure #engineering #innovation #performance #assetmanagement
