The Municipalidad de San José is offering up a solution to poor road conditions in the country, testing a new technology on the side road of the Torre Mercedes, Calle 24, on Paseo Colón.
The process is called “whitetopping”, the covering of an existing asphalt pavement with a layer of Portland cement concrete.
Whitetopping is divided into types depending on the thickness of the concrete layer and whether the layer is bonded to the asphalt substrate.
According to a search on the web, the process of Whitetopping is beneficial when fast placement is critical, use to replace damage or worn-out asphalt in low-speed urban road ways and residential roads. The curing time is less than 24 hours, and many ultra-thin whitetopping projects can reopen traffic within 1-2 days.
