The aim of this paper is to present the design and assembly of a field bench to check the solar reflectance of opaque surfaces based on the standard method ASTM E1918. For the development of the bench design, the computer program Solidworks was used. Two solar radiation sensors (pyranometers) were used to measure the reflected radiation, and the sensor signal readings were performed with the aid of a digital multimeter. Two reflectance measurements were performed on a 4x4m test surface of white stone pavement “Petit Pavé”. It was observed in the results of the reflectance measurements a variation of only 1% between the measured values. It was emphasized by this study the importance of developing methods and construction of measuring apparatuses as well as application standards standardized assessment procedure. In addition, the thermal characterization of construction materials generates useful information for designing and constructing buildings and public spaces, contributing to the reduction of the urban heat island and improving the thermal comfort of users.
