In tropical countries, roads built with asphalt layers must be made with bituminous mixtures
containing asphalt that is reasonably stiff to increase resistance against permanent …

High field density is desired for improving the durability of asphalt pavements. This research
aims to develop Superpave 5 mixtures (more compactable than traditional Superpave …

Abstract Hot Mix Asphalt (HMA) has been used over the years for laying roads. It required
the aggregate and the binder to be heated to temperatures above 160 C (320 F). Heating …

Compaction of hot mix asphalt (HMA) requires high temperatures in the range of 125 to 145°
C to ensure the fluidity of asphalt binder and, therefore, the workability of asphalt mixtures …

This research addresses the need to professionalise the asphalt construction process. A
distinctive action research strategy is designed and carried out to progressively improve …

The approach used to identify a compaction temperature in the laboratory, based on binder
viscosity, provides a single compaction temperature whereas, on-site, a roller operates …

This study attempts to understand the effect of Zy as an antistripping agent on the moisture
resistance of rubberized warm mix asphalt (WMA) mixtures using the surface free energy …

The compactability is a very important characteristic of asphalt. Proper asphalt compaction
ensures that the mixture achieves the planned lifetime, the bearing capacity and the …

The basic concept of warm mix asphalt (WMA) technologies is to reduce the asphalt binder
viscosity, which allows the asphalt to attain a suitable viscosity to coat the aggregates and …

Ten to fifteen years ago I certainly did not expect to do and finish a doctoral program. Now, I
feel it is a logical result of four years of hard work. I am inspired by László Polgár, a …
