Zhang, H. (author)With the attempt to reduce traffic noise, porous asphalt (PA) mixture is widely used as a wearing course on the highways in the Netherlands. However, due to the open structure, PA mix pavement easily suffers from the loss of individual aggregates from its surface, which is named as ravelling. After the initial ravelling, the damage can rapidly...doctoral thesis 2022

Mousavi Rad, Sina (author), Kamboozia, Neda (author), Anupam, K. (author), Saed, Seyed Ataollah (author)First, porous asphalt (PA) pavement possesses a lower strength and lifetime compared to typical dense-grade asphalt mixtures due to its large empty space structure. Second, PA pavements' fatigue life and durability are affected significantly by climate factors; the two most critical factors being aging conditions and moisture actions. Third,...journal article 2022

Xu, S. (author), Liu, X. (author), Tabakovic, A. (author), Schlangen, E. (author)Microwave heating has been shown to be an effective method of heating asphalt concrete and in turn healing the damage. As such, microwave heating holds great potential in rapid (1–3 min) and effective damage healing, resulting in improvement in the service life, safety, and sustainability of asphalt pavement. This study focused on the microwave...journal article 2021

Al Khateeb, Loay (author), Anupam, K. (author), Erkens, S. (author), Scarpas, Athanasios (author)The paper aims to simulate the micromechanical behavior of asphalt mixtures during the compaction process using the Discrete Element Method (DEM). The interactions between the components of a Porous Asphalt (PA) mixture were represented using an Elastic Viscoelastic Contact Model (EVCM), which is a user-defined model implemented in EDEM...journal article 2021

Zhang, H. (author), Anupam, K. (author), Scarpas, Athanasios (author), Kasbergen, C. (author), Erkens, S. (author)Asphalt mixtures with high porosities (known as porous asphalt (PA) mixes) are becoming a popular choice among road authorities as it provides better skid resistance while also reducing tire-pavement noises. Towards the design and manufacture of PA mix pavement, the evaluation of the mechanical properties of PA mixes is of great importance....journal article 2021

Ren, S. (author), Liu, X. (author), Xu, Jian (author), Lin, P. (author)Porous asphalt pavement is widely used due to its adequate water permeability, noise reduction and skid resistance. The study aims at exploring the potential of using the crumb rubber/styrene–butadienestyrene (CR/SBS) modified bitumen as high-viscosity binder for porous asphalt mixture, and investigating the effect of swelling and degradation...journal article 2021

Tabakovic, A. (author), O’Prey, Declan (author), McKenna, Drew (author), Woodward, David (author)A problem increasingly faced by airport authorities is the maintenance of runways. Due to their large aircraft loadings associated with take-off and landing operations, runways experience surface deterioration. Poor quality runway surfaces cannot be tolerated in such an environment. Maintenance issues must be carried out to maximise safety and...journal article 2019

Zhang, H. (author), Anupam, K. (author), Scarpas, Athanasios (author), Kasbergen, C. (author), Erkens, S. (author)Within the pavement engineering community, porous asphalt (PA) mixes are regarded as mixes capable of reducing noise and improving wet skid resistance. However, these mixes are likely to have the distress of ravelling. In order to analyse the propensity of a given PA mix for ravelling, the homogenisation technique can be considered as an...journal article 2019

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

Liu, Q. (author)Porous asphalt shows excellent performance in both noise reduction and water drainage. Although porous asphalt has these great qualities, its service life is much shorter (sometimes only half) compared to dense graded asphalt roads.
