There are different types of bitumen based on the place of use and its manufacturing method, and their heat resistance, viscosity, and insulation level in different conditions are based on the latest standards of the Organization for Standardization (ISO) according to the standards, 1-12505 to 12505- 10 is set. We at Dejpa Laboratory are ready to evaluate the bitumen samples sent by you according to their type with the most up-to-date equipment.

We believe that by increasing the knowledge level of the activists in this field, we have created special courses to train students and people interested in this field. These courses include full training of bitumen classified according to the degree of penetration, bitumen classified according to performance, bitumen classified according to viscosity, soluble bitumen, emulsion bitumen and modified bitumen.
