The colloidal structure of bitumen: Consequences on the rheology and on the mechanisms of bitumen modification

Advances in Colloid and Interface Science, 2009
The use of bitumen as a construction material dates back to antiquity. The materials in use then were mostly naturally occurring in contrast to modern bitumens which have become highly technical artificial materials. This article reviews the current understanding of bitumen structure and the consequences in terms of properties, with a strong emphasis ...

Investigation on physical properties of waste cooking oil – Rejuvenated bitumen binder

Construction and Building Materials, 2012
Nowadays, the main problem pertaining to the use of the recycled asphalt pavement (RAP) material in hot mix asphalt (HMA) is the ageing of bitumen, which limits the percentage of applied RAP in the HMA.

Bitumen

, 2007
Bitumen was analyzed by modulated differential scanning calorimetry (MDSC). This method allows for the deconvolution of overlapping reversing and non-reversing thermal events and it allows for the observation of transitions not visible on the thermal ...

Effect of ageing process on bitumen and rejuvenated bitumen

Construction and Building Materials, 2017
Abstract In the last few decades, highway agencies and the paving companies have invested huge efforts on increasing the amount of reclaimed asphalt (RA) to be introduced in the production of new asphalt concrete (AC). This technique, so-called hot recycling of RA, offers several economical and environmental advantages tightly related to the ...
