ASPHALT PAVEMENTS HAVING HIGH SOLAR REFLECTANCE
The invention relates to asphalt pavements having high solar reflectance (SR), with an SR index greater than or equal to 33%, in accordance with LEED v4 BD+C certification, for continuous AC mixtures and discontinuous BBTM mixtures. The asphalt pavements are developed on the basis of physicochemical parameters that determine the type and composition of the mixtures and favourably influence the reflectance of the entire solar radiation spectrum, UV-VIS-IR, such as the mineralogical nature of the aggregate, granulometry, porosity and surface texture, and type of binder and metal oxide pigment additives used. As preferred claimed embodiments of the invention, AC16 D mixtures, BBTM 5A or BBTM 8A thin-wearing-layer mixtures, and reflective pavements with antislip properties have been developed, and the possibility of including RAP recycled material in the mixtures has been contemplated. With these new pavements, the heating of city surfaces is reduced, and consequently the ambient temperature, mainly in summer, thereby mitigating the urban heat island effect.
