Traditional design procedures of asphalt mixtures are based on volumetric parameters and the compliance with the mechanical performance, while functional properties receive less attention. Additionally, even though the ...

This paper describes the development of novel/state-of-art computational framework to accurately predict the degree of binder activity of a reclaimed asphalt pavement sample as a percentage of the indirect tensile strength ...

En el presente artí­culo se presenta una nueva metodologí­a para la caracterización mecánica de mezclas asfálticas con particular interés en las mezclas recicladas, lo que se traduce en la definición de ensayos de laboratorio ...

Cold in place recycling, as an alternative to milling and standard replacement, shows a series of technical, economic and environmental advantages, which have done its use to grow in Spain, especially from 1990 onwards. ...

Asphalt binder characterization is a complex and difficult task due to its rheological behaviour. Indeed it has been traditionally realized by means of simple tests at an established temperature. An added challenge is that ...

Fatigue cracking and thermal shrinkage are two distress mechanisms that should be considered in asphalt mixtures and pavements design. Both distresses are complex and difficult to simulate in laboratory, especially the ...

Con objeto de evaluar la tenacidad de las mezclas bituminosas, el Laboratorio de Caminos de la Universidad Politécnica de Cataluña ha desarrollado un nuevo ensayo de tracción directa aplicado a probetas prismáticas. En ...

Fatigue is associated with the deterioration caused by applying repeated loads, and is affected by temperature or aging. Generally, time sweep tests are used to simulate fatigue, in order to obtain the fatigue laws. However, ...

Photoluminescent materials used on street and road pavements could absorb solar energy during the day and emit it at night, which will save energy and improve visibility with a consequent improvement in road safety. The ...
