Modified Asphalt Using Buton Natural Rock Asphalt

Journal of Advanced Civil and Environmental Engineering
he characteristics of asphalt mostly determine how well asphalt pavements work. High temperatures can cause stress on the asphalt surface layer. At high temperatures, irreversible alteration or bubbling occurs and leads to spalling as it travels. This is due to the slow movement of the asphalt components in the pavement mixture, which resists the ...
