PROJECT UPDATES AT BOTTOM OF THIS PAGE
The City of Sunset Hills Public Works Department will contractor for the application of a small aggregate (1/4") chip seal to three (3) streets. A chip seal involves the application of and asphalt binder with small rock to the surface of the street. This material is rolled into the binder with a rubber tire'd roller.
Specifically, this 1/4" Chip Seal product was developed in recent years and has proved more effective in reducing loose rock (knock off) and providing a quick solid surface that provides an effective surface to keep water from attacking the structural sub-base of the street. The contractor will make the application of the product to the streets listed in the contract and return a week later to sweep off any remaining loose knock-off. After that, the striping sub-contractor will return within a couple of weeks to re-apply pavement markings.
