Abstract EN
Starting from the eighties, the use of nanoadditives registered an increasing attention in the scientific and patent literature, especially for the case of polymeric nanocomposites.
In the last decade, this involved bituminous materials, modified either with nanosized fillers or with polymeric nanocomposites.
One of the expected benefits is an increased resistance of the binder to aging.
After a short introduction underlining the uncertainties and risks of artefacts in aging tests, a review is given, focusing on the antiaging properties of layered silicates, which are by far the most important nanoadditives for bitumens.
Together with layered silicates, other materials such as nanohydrated lime, nanosilica, and layered double hydroxides are mentioned.
Preparation and characterization of the binary bitumen/layered silicate and ternary bitumen/layered silicate/polymer systems are described in order to individuate the aspects that influence the antiaging effect.
Even if the available literature is quite abundant and unanimously confirms that nanoadditives may improve bitumen durability, there is a lack of studies clarifying the involved mechanisms.
As it is for conventional fillers, it seems to be a combination of physical and chemical interactions.
Nanoadditives with different chemistries, porosities, and interlayer spacings differently absorb the polar components from the bitumen, thus affecting their predisposition to oxidative aging.
