The aim of this paper is to design a novel asphalt mixture capable of reducing tyre/pavement interaction noise for urban roads at speeds around 50 km/h. To this end, various mechanical and functional tests were carried out both in the laboratory and

Based on the positive results of most of the studies using virgin fibres to reinforce asphalt mixes, this work proposes the use of recycled fibres in order to go a step further in terms of environmental impact and cost-efficiency. Different experimen

Porous asphalt (PA) mixtures are gaining wider acceptance in pavement construction due to their benefits in terms of road safety, noise mitigation and stormwater management. Increasing demands, such as those imposed by climate change, require the des

Cold asphalt mixtures are more sustainable because they are manufactured at ambient temperature. However, they are much less applied because they take longer time in the curing process due to the water contained in the asphalt emulsion, which delays

Tensegrity structures are prestressed and self-stable pin-connected frameworks built up mainly from two kind of elements, in compression (bars) and in tension (tendons). It has been 75 years since the first official appearance of tensegrity, although

In previous studies, different additives and modifiers have been studied to improve the properties of asphalt concrete mixtures, whose main failures are plastic deformation and cracking. In this research, the improvement of the properties of asphalt

Polymers are widely used to improve the mechanical performance of asphalt mixtures. Among them, styrene butadiene styrene (SBS) is the most commonly used, especially in the wet modification of virgin bitumen. This method, which is extensively utilize
