Use of bitumen-stabilised ballast for improving railway trackbed conventional maintenance (2018)
Journal Article
D'Angelo, G., Sol-Sánchez, M., Moreno-Navarro, F., Lo Presti, D., & Thom, N. (2018). Use of bitumen-stabilised ballast for improving railway trackbed conventional maintenance. Géotechnique, 68(6), 518-527. doi:10.1680/jgeot.17.P.022

Despite its many advantages, ballasted track needs frequent maintenance to ensure an adequate quality of service. However, tamping, traditionally used to correct geometry, causes ballast degradation and loosening of the already compacted ballast laye... Read More

Novel performance-based technique for predicting maintenance strategy of bitumen stabilised ballast (2017)
Journal Article
D'Angelo, G., Bressi, S., Giunta, M., Lo Presti, D., & Thom, N. (2018). Novel performance-based technique for predicting maintenance strategy of bitumen stabilised ballast. Construction and Building Materials, 161, 1-8. doi:10.1016/j.conbuildmat.2017.11.115

Despite being the most used worldwide, railway ballasted tracks presents high maintenance cost related to ballast settlement and particle degradation. With the aim of reducing life cycle costs, bitumen stabilised ballast (BSB) has been recently propo... Read More

Linear and nonlinear fractional hereditary constitutive laws of asphalt mixtures (2016)
Journal Article
Presti, D., D’Angelo, G., Pinnola, F., Di Paola, M., Mino, G., Di Mino, G., …Presti, D. L. (2016). Linear and nonlinear fractional hereditary constitutive laws of asphalt mixtures. Journal of Civil Engineering and Management, 22(7), 882-889. doi:10.3846/13923730.2014.914104

Abstract: The aim of this paper is to propose a fractional viscoelastic and viscoplastic model of asphalt mixtures using experimental data of several tests such as creep and creep recovery performed at different temperatures and at different stress l... Read More

Bitumen stabilized ballast: a potential solution for railway track-bed (2016)
Journal Article
D'Angelo, G., Thom, N., & Lo Presti, D. (2016). Bitumen stabilized ballast: a potential solution for railway track-bed. Construction and Building Materials, 124, 118-126. doi:10.1016/j.conbuildmat.2016.07.067

Railway ballast degradation under dynamic loads progressively leads to loss of mechanical performance and geometry of the track, so that maintenance interventions are frequently needed. In order to systematically avoid this issue, recently solutions... Read More
