**2.2.6 Asphalt products**

In the urban open spaces, asphalt products are only used in the form of asphalt concrete, which is widely used for the paving of streets. Asphalt surfaces's temperatures were measured in most urban open spaces. In most cases, their surface temperatures in the afternoon (13:30 - 16:30) were over 50 oC, in some cases, greater than 60 oC. At this point, a distinction should be made between newly and old paving. The weathering of asphalt concrete causes the appearance of its aggregates to be usually white, crushed, light-coloured stone and a subsequent increase in its reflectivity. Apart from the apparent differences in the maximum and mean temperatures, it is interesting to note the surface temperatures of the material around sunset (about 19:30). At this time, air temperatures are around 32 oC, while surface temperatures of new asphalt are 7 oC higher, and that of old asphalt are about 4.5 oC higher, while of shaded asphalt are 2.5 oC lower.
