Asphalt shingles sealer from Asphalt Home Depot and other major manufacturers, which were installed at some of the country’s busiest intersections in the past decade, is so popular among local motorists that a new sealer for the same intersection has just been released.
The sealer, which was originally created to reduce friction in asphalt, has been promoted as the future of highway sealer because it uses a water-resistant polymer that can withstand extreme temperatures.
The asphalt sealer that’s in use at the intersection of Haham Al-Bab and Tulkarem Streets in Jerusalem’s central business district has a thick layer of asphalt shingled and bonded to the roadway surface to form a seal that can be applied with a variety of techniques.
While this is an ideal approach for drivers, the asphalt shingle sealer isn’t quite as strong as the asphalt sealers that are currently used in some U.S. cities, said Yossi Al-Saleh, director of the Jerusalem Transportation Authority’s traffic safety department.
The cement sealer used at the intersections is a different material, and has an added layer of concrete to hold the seal in place.
The cement sealers were designed specifically for the intersections in order to prevent damage from vehicles driving on the surface of the roadway, he said.
But Al-Shaleh said the cement seal of the asphalt was less effective at reducing friction and was therefore replaced in the beginning of this year by a waterproof sealer.
The new asphalt sealant is expected to be in use for at least a year, according to the Jerusalem transportation authority.
