The recommended temperatures of SMA mixtures with road bitumens according to EN 12591 are given in the standard EN 13108-5. The minimum temperature of delivery to a laydown site and the maximum production temperature in an asphalt plant are provided there. When using a modified or special binder, one should follow the information passed on by its producer or as determined in other documents.
Example temperatures for two of the most common road bitumens (EN 12591) used for SMA are as follows:
• 50/70— minimum temperature 150°C, maximum temperature 190°C
• 70/100— minimum temperature 140°C, maximum temperature 180°C
