“…Thus, ion-exchange reactions with quaternary ammonium salts with alkyl chains are required in order to render the nanoclay compatible with bitumen. Furthermore, a larger interlayer distance facilitates the insertion of the bitumen molecules in-between the layers during melt blending [3,12]. Depending on the extent of insertion, different morphologies are distinguished (from poor to high quality): flocculated silicate platelets, intercalated and exfoliated structures [10,11,13].…”

“…In this regard, its mechanical behaviour is highly influenced by the temperature, in such a way that, at low temperature, bitumen becomes fragile (thermal cracking), whilst at high temperature, it may undergo permanent deformation (rutting) [1]. Additionally, bitumen can also undergo ageing provoked by oxygen diffusion and UV radiation, which increases its thermal susceptibility and provoke premature fail [2,3].…”

Graphical abstract ABSTRACTPolymer modified bitumens (PMBs) have largely been utilized as a construction material. However, lack of affinity between bitumen and polymer leads to phase separation, and eventually, performance depletion. In this paper, alternative formulations of bitumen with an organically-modified montmorillonite (OMMT) Cloisite 20A® and polymeric methylene diphenyl diisocyanate (MDI) were prepared by melt blending. Their comprehensive rheological characterization evidenced improved linear viscoelastic properties when OMMT is added, reveali...

Uneven roads surface can be observed on bituminous pavements. This is due to moving loads and climate conditions. If the observed deformations exceed the elastic limit, important damages can occur, so new materials are used to improve the stiffness modulus of bituminous mixtures. To achieve this, a modified bituminous concrete by addition of the PR PLAST Sahara (produced by PR industries and PLAST for Plastic) mainly used in arid region has been studied. The use of this additive at various percentages 0.1, 0.3, 0.6 and 0.9 by weight of bituminous concrete has been investigated to determine its stiffness modulus. An experimental design using the Taguchi tables has been elaborated to reduce the number of tests. Marshall and NAT (Nottingham asphalt tester) tests have been carried out, and a mathematical model of the stiffness modulus has been proposed.
