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.

Staphylococcus aureus is a feared pathogen (MRSA, multi-resistant S. aureus) due to frequent resistances against many antibiotics, especially in hospital infections. Researchers at the Paul-Ehrlich-Institut have identified immunological processes that prevent a successful immune response directed against the pathogenic agent. The delivery of bacterial proteins with RNA adjuvant or messenger RNA (mRNA) into immune cells allows the re-direction of the immune response towards an active defense against S. aureus. This could be of significant importance for the development of an effective vaccine. PLOS Pathogens has published these research results online on 25 May 2017.
Staphylococcus aureus (S. aureus) is a bacterium that colonizes by far more than half of the skin and the mucosa of adults, usually without causing infections....
Physicists from the University of Würzburg are capable of generating identical looking single light particles at the push of a button. Two new studies now demonstrate the potential this method holds.
The quantum computer has fuelled the imagination of scientists for decades: It is based on fundamentally different phenomena than a conventional computer....
An international team of physicists has monitored the scattering behaviour of electrons in a non-conducting material in real-time. Their insights could be beneficial for radiotherapy.
We can refer to electrons in non-conducting materials as ‘sluggish’. Typically, they remain fixed in a location, deep inside an atomic composite. It is hence...
Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.
Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...
