The effect of polymer modified binders on the long-term performance of bituminous mixtures: The influence of temperature

摘要: Abstract Asphalt pavements are very susceptible to the effects of temperature, and their mechanical performance is affected by climatological conditions which they exposed. Polymer-modified binders have been developed in order reduce impact temperature on these infrastructures. Although allow for a more stable response an improvement properties bituminous mixtures, increase costs associated with production makes them less competitive comparison traditional binders, use restricted surface layers roads high levels traffic. Furthermore, at certain temperatures, laboratory tests used during design mixtures failed reveal many differences between conventional modified bitumens. In assess real benefits using polymer-modified this research evaluates long-term asphalt different temperatures. The study was carried out both binder mixture level, results showed that effect induced presence polymers closely linked tested. Thus, effectiveness will depend climatic
