In most existing pavement design methods, pavements are analyzed using linear elastic multilayer theory, with the assumption that isotropic conditions are present in the structural layers of the pavement section. There are ...

Pavement sustainability is measured using various methodologies which often focus on only certain aspects of sustainability. Methods to quantify and unify holistic sustainability in terms of economic, environmental and ...

Construction, maintenance and demolition of pavements are often considered the only activities impacting the environment. This paper shows that user emissions, influenced by factors such as road roughness and climate change, ...

For many years, South African road authorities have taken measures to reduce costs of road construction, vehicle operating costs as well as road fatalities while enhancing road performance to improve the sustainability of ...

Asphalt mix designs tend to optimise the load transfer via aggregate skeletons as main mechanism to provide rut resistance, often to the detriment of durability. Permeability, as a significant durability indicator, is ...

Accurate numerical modelling of the behaviour of road pavement layers is an important requirement for the design and evaluation of road pavements. This modelling includes the prediction of pavement performance under the ...

Social consideration, assessed using a social life cycle assessment (S-LCA), is a relatively new concept that has yet to be standardised. Attempts at measuring social sustainability in pavement management have been made ...
