Influence of start temperature on tensile stress testing of restrained asphalt concrete specimens

Dejan Hribar, Marjan Tušar, Bernhard Hofko, Ronald Blab

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.

Keywords
