#### 2.3.1. Conventional Property Tests

The conventional property tests, including penetration at 25 ◦C (ASTM D 5), softening point (ASTM D 36), ductility at 10 ◦C (ASTM D113) and the Fraass breaking point (BS EN 12593) [38], were carried out.

The viscosity of the asphalt binder was tested with a Brookfield rotational viscometer according to ASTM D 4402. The measurements were conducted from 135 ◦C to 175 ◦C to assess its construction workability and temperature sensitivity.
