How we measure 'reads'
A 'read' is counted each time someone views a publication summary (such as the title, abstract, and list of authors), clicks on a figure, or views or downloads the full-text. Learn more
The fracture resistance of asphalt materials under repeated traffic loads significantly influences the service life of asphalt pavements. The numerical simulation of asphalt materials based on a form of fracture mechanics is considered as an efficient way to model fracture damage. Unlike traditional fracture mechanics approaches assuming the existe...
Asphalt binder is inevitably aged by ultraviolet (UV) light during its service period. UV ageing can significantly decrease the technical properties of asphalt binder. The sensitivity of asphalt to UV ageing and thermal-oxidative ageing differs, such that the UV ageing performance cannot be determined based on the thermal-oxidative ageing performan...
The precise, quick and efficient simulation of asphalt concrete is an important step to select asphalt mixtures for a range of applications. A method to create virtual aggregates based on aggregates' topological properties and aggregate skeletons like those of asphalt concrete using a physics engine is proposed. It can produce hundreds of virtual a...
This paper addresses the influence of the silt content and concrete density on the physical and mechanical properties of foamed concrete, including the compressive and flexural strength, water absorption, pore structure, and hydration products. The results of the experimental tests show that the compressive and flexural strength of the foamed concr...
