Asphalt suffers damage through the combination of infiltrating water and the ongoing burden of moving vehicles. It appears clear from the damage to the road surfaces that water has a negative effect on the material properties of the asphalt components and their binding.
Kringos succeeded in using her own computer program to model the deterioration in asphalt arising from the combined action of water infiltration and mechanical load. From the simulations it appears to be vitally important to measure the variables important for water damage, for all the individual asphalt components. These variables include the maximum moisture retentiveness, the moisture diffusion and the binding strength of the various asphalt components. Differences here appear to have an enormous influence on the degree of asphalt damage.
Kringos’ program can make a significant contribution to developing an improved and structured material selection which should lead to asphalt types which can last longer. In her research she applied her model particularly to American asphalt mixtures, and is currently busy adapting her results to the Dutch situation.
Kringos’ fundamental approach is entirely new in the asphalt world and in the future it will lead to better material selection, better maintenance planning and advanced asphalt mixture optimisation. Last year Kringos was honoured as the first European scientist to receive an annual PhD award from the Association of Asphalt Paving Technologists (AAPT) in the United States, for her pioneering work. She received her PhD with honors with this research on Monday June 4.

Using ultrafast flashes of laser and x-ray radiation, scientists at the Max Planck Institute of Quantum Optics (Garching, Germany) took snapshots of the briefest electron motion inside a solid material to date. The electron motion lasted only 750 billionths of the billionth of a second before it fainted, setting a new record of human capability to capture ultrafast processes inside solids!
When x-rays shine onto solid materials or large molecules, an electron is pushed away from its original place near the nucleus of the atom, leaving a hole...
For the first time, physicists have successfully imaged spiral magnetic ordering in a multiferroic material. These materials are considered highly promising candidates for future data storage media. The researchers were able to prove their findings using unique quantum sensors that were developed at Basel University and that can analyze electromagnetic fields on the nanometer scale. The results – obtained by scientists from the University of Basel’s Department of Physics, the Swiss Nanoscience Institute, the University of Montpellier and several laboratories from University Paris-Saclay – were recently published in the journal Nature.
Multiferroics are materials that simultaneously react to electric and magnetic fields. These two properties are rarely found together, and their combined...
