Zhang, H. (author), Anupam, K. (author), Scarpas, Athanasios (author), Kasbergen, C. (author)ZOAB (Zeer Open Asphalt Beton) is the most widely used asphalt mixture in the Netherlands. As a type of open asphalt mixture, it is known to suffer from raveling distress. In order to analyze the propensity of raveling, micromechanical models are considered effective. However, most of the research work about micromechanical models has focused...journal article 2018

Zhang, H. (author), Anupam, K. (author), Scarpas, Athanasios (author), Kasbergen, C. (author)Within the pavement engineering community, open graded mixes (OGM) are regarded as mixes capable of reducing noise and improving wet skid resistance. However, during their design life, these asphalt mixes are known to suffer from a particular distress type known as raveling. This results in a premature failure of a road network. In order to...journal article 2018

Jing, R. (author), van Lent, Diederik (author), Kasbergen, C. (author), Scarpas, Athanasios (author), Liu, X. (author), Erkens, S. (author)When oxygen diffuses in a bituminous film, it also reacts, simultaneously, with the constituents of the bitumen and as such it is gradually depleted. This depletion process masks the characteristics of the actual diffusion process and complicates the determination of the diffusion coefficient needed for computation of oxygen concentration and...conference paper 2017

Srirangam, S.K. (author), Anupam, K. (author), Kasbergen, C. (author), Scarpas, Athanasios (author)The surface texture of the pavement plays a very important role in driving the frictional properties at the tire rubber-pavement interface. Particularly, the hysteretic friction due to viscoelastic deformations of rubber depends mainly on the pavement surface texture. In the present paper, the effect of micromechanical pavement surface...journal article 2017

Tang, T. (author), Anupam, K. (author), Kasbergen, C. (author), Scarpas, Athanasios (author)Stopping distance includes driver thinking distance and braking distance. Braking distance is one of the basic standards for road design and maintenance practices. Adequate tire–pavement skid resistance plays a significant role in reducing braking distance and consequently enhancing road safety. With technology such as the antilock braking...journal article 2017

Apostolidis, P. (author), Liu, X. (author), Kasbergen, C. (author), Scarpas, Athanasios (author)“Aging” is the accumulation process of diverse detrimental changes in molecular structures with advancing age. Resistance to aging is termed “durability.” Complex molecular systems such as asphalt binder (AB) need to be protected against aging. This paper provides a state-of-the-art review of antiaging technologies used to prohibit or to...journal article 2017

Erkens, S. (author), Leegwater, G.A. (author), Scarpas, Athanasios (author)Asfalt heeft de aantrekkelijke eigenschap dat het zichzelf kan herstellen na schade. Er is echter tot op heden geen betrouwbare methode om de healingcapaciteit van een asfaltmengsel te bepalen. Bij het healingproces van een discrete scheur spelen twee processen een rol, namelijk het in contact komen van de oppervlakken van de scheur; het...conference paper 2016
