Laboratory Equipment​​​​​​

This device can measure the complex shear modulus G^*and the phase angle (δ) at medium and high temperatures. The Dynamic Shear Rheometer evaluates the effect of loading duration and temperature on bitumen samples to investigate their viscoelastic and elastic properties.
​​​​​​​

In 2017, a new DSR device was added to the laboratory, serving as a suitable complement to the older DSR in the Superpave Laboratory of the Faculty of Civil Engineering. This new device provides researchers with much broader experimental capabilities, including tests such as MSCR and LAS.
​​​​​​​

This device measures the creep stiffness S(t)and the slope of the logarithmic stiffness curve over time (m-value). The obtained stiffness values can be used to determine the low-temperature fracture resistance properties of bitumen.

​​​​​​​

This device is used as a complement to the Bending Beam Rheometer for determining the low-temperature fracture properties of bitumen.

​​​​​​​The test applies tension at a controlled rate and measures the stress and strain at the moment of sample failure to evaluate the bitumen’s fracture characteristics.​​​​​​​

The Brookfield DVII+ viscometer is designed to measure the viscosity of liquids at high temperatures (up to 300 °C / 572 °F). The measured viscosity is used to determine the mixing and compaction temperatures of asphalt mixtures and to assess the pumpability of bitumen in refineries or in hot-mix asphalt equipment and machinery.

This device is used to simulate the aging of bitumen during the production and paving of asphalt mixtures. Bitumen samples are placed in special bottles and rotated inside the oven at 163 °C for 85 minutes, while a flow of hot air is applied to the samples. This process accelerates the aging (oxidation) of the bitumen.
​​​​​​​

This device simulates the aging of bitumen during its service life. In this test, bitumen obtained from the RTFO is exposed to high-pressure air and elevated temperatures (90–110 °C) for 20 hours to accelerate the aging process. The resulting bitumen can then be evaluated for rheological properties using DSR, BBR, and DT devices.
​​​​​​​

The Superpave gyratory compactor is used to prepare asphalt samples for evaluating the mechanical and volumetric properties of hot mix asphalt (HMA) under conditions simulating field compaction.



​​​​​​​

This device is used to determine the percentage of bitumen in uncompacted hot mix asphalt (HMA) samples, as well as in cores extracted from constructed pavements. The bitumen in the asphalt mixture is burned in a furnace at 540 °C to measure its content.
