Molecular dynamics (MD) simulation plays an effective role in predicting the critical properties and explaining the macroscale phenomenon at the nanoscale. This review summarized the application cases of MD simulations in various bitumen systems, considering aging, modification, and rejuvenation factors. Meanwhile, the potential relationships...

The cohesive and adhesive performances of bituminous materials significantly affect the service life of asphalt pavement. The molecular dynamics (MD) simulation method has been proved as an effective tool to predict the thermodynamics parameters of different multisubstance and multi-phase bitumen models during different diffusion, self-healing,...

The demand for alternative bitumen which could fully/partially replace Petroleum sourced bitumen for pavement construction is globally increasing. The increase in demand can be associated with several factors: depletion in crude oil resources, advances in crude oil refining processes, increased demand for highway infrastructure, and regional...

The mechanical properties of asphalt mixture are always required for the evaluation of the durability of pavements. In order to obtain these properties without conducting expensive laboratory tests and using calibrated empirical models, research studies have been carried out to develop micromechanics-based models. Continuum-based...

In the context of climate change and global warming, the attention on the environmental cost of pavements is increasing. To scientifically quantify the environmental cost of pavements, accurate prediction of rolling resistance and fuel consumption is important. In this paper, a comprehensive review on rolling resistance of asphalt pavements...

Rapport in opdracht van de Gemeente Rijswijk. Ter verbetering van de verbinding per openbaar vervoer tussen Den Haag en Rijswijk Steenvoorde zijn plannen gemaakt voor de aanleg van een tramlijn over de Burgemeester Elsenlaan en door de Plaspoelpolder. Op basis van het in Den Haag en omstreken gebruikte vervoermodel, het AVVO-model van DHV, is...

Het zelfherstellend vermogen, of de healingscapaciteit, van asfaltmengsels wordt in de meeste ontwerpmethoden voor wegverhardingen meegenomen. De kennis over dit zelfherstellend vermogen is gebaseerd op ervaringen en onderzoeken uit het verleden en de werkelijke mechanismen erachter zijn niet bekend. Hierdoor is het moeilijk om voor nieuwe...

In this report we present the background, the scientific and experimental approach and the results of AFM experiments performed on two different batches of bitumen. The specific bitumen researched in this project has also been studied in the context of the InfraQuest project ‘Pragmatisch Healing Onderzoek’. It has been known for quite some time...

In part one of this report, general transport and transport-flow measures are described. By using other modes of transport than road-vehicles, it is possible to save energy. An advanced park-and-ride system can lead to a 27% reduction in energy use per passengerkilometre; in 2040 at most 10% of the total number of passengerkilometres can be...

Ypenburg per vliegend openbaar vervoer, een titel die min of meer de conclusie van het onderzoek weergeeft: een toekomstige woonwijk Ypenburg is dusdanig te ontsluiten met het openbaar vervoer, dat geconcureerd kan worden met de auto ('vliegensvlugge' OV-verbindingen). De eerste stap die in het ontwerp genomen moet worden is het vaststellen van...

Rapport opgesteld door de Technische Universiteit Delft, Vakgroep Infrastructuur in opdracht van de Rijksplanologische Dienst (RPD). Er bestaat een zekere wisselwerking tussen vervoersystemen en de ruimtelijke ordening. Om deze wisselwerking in beeld te brengen is gezocht naar kenmerken waarmee vervoersysteem en ruimtelijke ordening beschreven...

In dit rapport wordt een onderzoek beschreven met vijf verschillende wrijvingsreductiesystemen. De aanleiding was een verandering in de EN 12697-25, waarbij Latex wrijvingsreductie vervangen is door Teflon, terwijl er flink wat onderzoek is dat liet zien dat Teflon voor asfalt minder effectief is dan Latex. Testen van hetzelfde asfalt met beide...

Fatigue resistance of asphalt concrete is usually evaluated by means of fatigue tests, like repeated load four point bending tests. These tests are rather time consuming and, therefore, not suited for performance based specifications. In this article a new, faster procedure to determine the fatigue characteristics is introduced. The procedure is...

In road engineering research and design the principles of material mechanics have not yet become a standard tool. In this contribution a project aimed at applying these principles to asphalt concrete is presented. Attention is paid to the differences between the standard test procedures and those based on mechanics considerations, presenting...
