Li, J. (author), Liu, X. (author), Scarpas, A. (author), Tzimiris, G. (author)In the Netherlands an asphaltic surfacing structure for orthotropic steel bridge decks mostly consists of two structural layers. The upper layer consists of Porous Asphalt (PA) because of reasons related to noise hindrance. For the lower layer a choice between Mastic Asphalt (MA) or Guss Asphalt (GA), can be made. In this paper, a typical Dutch...conference paper 2012

Lu, S. (author), Li, J. (author), Van Zuylen, H. (author)Different aspects of the traffic control system in the CBD of Changsha have been evaluated. A general issue is the safety conditions, which are evaluated qualitatively. The second issue is the low saturation flow observed on the intersections, that appear to be 20 to 30% lower than the ones in comparable situations in Europe or North America....journal article 2012

Oregui, M. (author), Li, Z. (author), Dollevoet, R.P.B.J. (author)Rail joints have a shorter service life than most other railway track components. The discontinuity between rail ends turns the rail joint into a weak spot, and consequently, into a track component demanding more frequent maintenance measures, which result in high maintenance costs. Moreover, difficulties are often found when assessing the...conference paper 2012

Huang, F. (author), Xia, Z. (author), Li, F. (author), Guo, L. (author), Yang, F. (author)Hydrological changes of the Irtysh River were analyzed concerning the changes of annual runoff and its distribution features within a year measured by coefficient of variation and concentration degree. Abrupt changes were detected by the heuristic segmentation method. Possible causes of the hydrological changes were investigated considering...journal article 2012

Tzimiris, G. (author), Liu, X. (author), Scarpas, A. (author), Li, J. (author), Hofman, R. (author), Voskuilen, J. (author)Due to lightweight and flexibility, orthotropic steel deck bridges become popular the last decades but several problems were reported in relation to asphalt surfacing materials such as rutting, cracking, loss of bond between the surfacing system and steel deck. In the Netherlands a surfacing structure for orthotropic steel bridge decks mostly...conference paper 2013

Liu, X. (author), Scarpas, A. (author), Li, J. (author), Tzimiris, G. (author), Hofman, R. (author), Voskuilen, J. (author)In order to adequately characterize the adhesive bonding strength of the various membranes with surrounding materials on orthotropic steel decks and collect the necessary parameters for FE modeling, details of the Membrane Adhesion Test (MAT) are introduced. Analytical constitutive relations of the MAT device have been derived using the same...conference paper 2013

Li, J. (author), Scarpas, A. (author), Tzimiris, G. (author), Kasbergen, C. (author), Hofman, R. (author), Voskuilen, J. (author)The French five-point bending test (5PBT) provides a laboratory scale test that allows studying the fatigue resistance of surfacing systems on orthotropic steel deck bridges (OSDB). The surfacing structure for OSDB in the Netherlands consists mostly of multilayer system: top porous asphalt layer, guss asphalt layer, steel deck and two membrane...conference paper 2013

Li, J. (author), Liu, X. (author), Scarpas, A. (author), Tzimiris, G. (author)Light weight orthotropic steel bridge decks have been widely utilized for bridges in seismic zones, movable bridges and long span bridges. In the last three decades, severe problems were reported in relation to asphaltic surfacing materials on orthotropic steel deck bridges. Earlier investigations have shown that the bonding strength of membrane...conference paper 2013

Li, S. (author)The Yellow River is known as the ‘mother river’ of the Chinese people, but is also said to be ‘China's Sorrow’ or the ‘Scourge of the Sons of Han’, because in history multiple major floods have had catastrophic effects on people and land along the 5000 km long river reaching from the Himalaya’s to the Bohai Sea. Three sections can be...doctoral thesis 2013

Li, W. (author), De Vriend, H.J. (author), Wang, Z. (author), Van Maren, D.S. (author)High-resolution morphological modeling of fluvial processes with complex, rapidly varying flows has been limited so far by model accuracy or computational efficiency. One of the most widely used numerical algorithms is based on the total variation diminishing method, solved by either upwind or centered approaches. An upwind scheme preserves high...journal article 2013

(author)This paper investigates changes in tire/pavement noise caused by variations in the road surface characteristics. This research is based on the analysis of noise and surface characteristics collected from sections with 25 mm thickness thin layer surfacings in the Netherlands. Investigations are first performed on the measured noise levels in 1...journal article 2013

Yang, Z. (author), Li, Z. (author), Dollevoet, R.P.B.J. (author)This paper presents a full finite element (FE) interaction model of wheel-track to study the wheel-rail impact noise caused by squat. The wheel, the rail and some other track components are modeled with finite elements in three dimensions, where necessary and appropriate. Realistic contact geometry, including geometric irregularity (squat) in...conference paper 2013

Li, M. (author)Noise levels due to road traffic have reached intolerable high levels in and around many urban areas all around the world. Because of health reasons and reasons of well- being these noise levels have to be reduced. The noise produced from the interaction between the rolling tyre and road surface is one of the most important contributions in the...doctoral thesis 2013

Li, N. (author)Fatigue characterization of an asphalt mixture is commonly estimated by laboratory fatigue tests. Based on the classical fatigue analysis, fatigue lives obtained from different test devices are not comparable even when they are performed at the same test conditions. It is believed that there are two main reasons causing the difference in fatigue...doctoral thesis 2013

Knowledge of the mechanisms of travel time unreliability enables the derivation of explanatory models with which travel time reliability can be predicted and utilized in traffic management. Inspired by the macroscopic fundamental diagram (MFD),...conference paper 2013

It includes both integer estimation and evaluation. For integer estimation, the LAMBDA method has been applied in a wide variety of GNSS applications. The method’s popularity stems from its numerical efficien-cy and statistical optimality....conference paper 2013
