Abstract

This paper presents the result of the Tensile Stress Restrained Specimen Tests on specimens of asphalt concrete AC 8 with bitumen 50/70 depending on two starting temperatures of +10 °C and +20 °C. The analysis of the results shows that there is only a non significant difference between these two start temperatures and the results are within the limit of standard precision. On the other hand, there is a difference between the results of two laboratory TU Wien and ZAG Ljubljana, who carried out the tests in accordance with EN 12697-46 at start temperature +20 °C.
