“…The high resistance of PMMA/ATH to heat, oxygen and degradation influenced the base bitumen's performance in intermediate temperature range, as determined by several physical tests and rheological measurements. In combination with paraffin wax, a positive effect on asphalt binder's performance was observed at elevated temperatures, although shear load magnitude was carefully selected . Nevertheless, effect of the ageing treatment on time‐dependent rheological behavior of bitumen with PMMA/ATH modifier was not carefully investigated.…”

This article deals with the influence of the ageing treatment on the viscoelastic behavior of PMMA/ATH modified paving bitumen. Waste composite powder (polymethyl methacrylate filled with aluminium trihydrate)-PMMA/ATH and Fischer-Tropsch wax were used as modifying agents for 70/100 paving grade bitumen. Measurements in intermediate temperature range were carried out under oscillatory shear conditions on a dynamic shear rheometer (DSR). Creep testing in low temperature range was conducted on a bending beam rheometer (BBR). The time-dependent behavior of investigated samples was presented in a form of relaxation moduli G(t) and E(t). Dynamic moduli, i.e., G 0 (x) and G 00 (x), were converted to relaxation modulus G(t) using the Schwarzl method. The interconversion between tensile creep compliance D(t), and tensile relaxation modulus E(t) was performed using the Hopkins and Hamming approach. It was found that modified binders are less susceptible to the oxidation process during bitumen ageing, since the viscoelastic properties changed less than for the base bitumen. Our results indicate that the use of waste PMMA/ATH in the selected bitumen altered the time-dependent deformation behavior of asphalt binder. The effect of ageing treatment on material functions was particularly manifested at longer times. Different stress relaxation behavior of modified binders could result in higher deformation resistance of asphalt mixture. POLYM. COMPOS., 00:000-000,

On the surface of asphalt pavements two types of damages are most common, namely the cracking and rutting. Surface cracking, which initiate at the surface of the wearing layer of asphalt, occurs most frequently, because a binder at low temperatures becomes too fragile. Rutting occurs at elevated summer temperatures, due to low viscosity of binder insufficient to sustain high traffic loads. As the binder in the asphalt layers mostly paving grade bitumen is used, which has a relatively small temperature range between too low and too high viscosity to withstand heavy loads. To increase the temperature range of bitumen in the bitumen various so-called modifiers are added. Most often SBS (styrene-butadiene-styrene block copolymer) is used to modify bituminous binder for higher traffic roads. SBS increases quality of asphalt, but it has many drawbacks; modifier is expensive, producer have to increase temperature when producing SBS modified asphalt mixtures and laying of asphalt course with SBS modified bitumen is more difficult than with paving grade bitumen. In this study, we found that the addition of Poly-methyl methacrylate/aluminium trihydrate (PMMA/ATH) composite in the asphalt mixture increases the resistance of asphalt layers to permanent deformations and increases durability of asphalt. With laboratory trials we managed to reduce proportional rut depth by a factor of three, when PMMA/ATH composite was added to bitumen. The highest degree of resistance to the formation of ruts, which was five fold lower than in the reference asphalt layer was achieved by adding a combination of PMMA/ATH composite powder and paraffin waxes in the bitumen. Already in 2009 test fields were built. First dry process of adding PMMA/ATH composite to asphalt mixture was applied and in 2013 wet process of adding PMMA/ATH composite to bitumen was utilized. Produced asphalt was successfully built in test fields and regular roads. In comparison to SBS we found some advantages of adding PMMA/ATH in the asphalt: cheaper additive, easier production of modified binder, there is no need for an elevated temperature at asphalt production, asphalt did not stick to shovels and it was found out that workability of asphalt is even improved.

“…These cut-offs and waste powder amount to approximately 1000 tons of PMMA/ATH waste every year in Slovenia alone. Different methods of recycling this particular waste have already been considered [9][10][11][12][13][14][15], but none of them has yet provided a simple, sustainable, and cost-effective solution. In the past few years, some researches have aimed to develop new methods of recycling or reusing PMMA/ATH waste and by-products [16][17][18][19].…”

This study investigated the morphologic and chemical properties of coatings based on PMMA/ATH powder and deposited by cold plasma spraying on wood and glass. Since the deposition of pure PMMA/ATH powder with air as process gas yielded coatings with insufficient abrasion resistance, two modifications of the basic process were investigated. Previous studies showed that replacing air as process gas with forming gas did not enhance the abrasion resistance, but the addition of a phenol-formaldehyde resin (PF) succeeded in stabilising the particle coatings. In this work, results from morphologic and chemical analysis suggested an encasement of the PMMA/ATH particles by plasma-modified PF and thus a fusion of individual particles, explaining the enhanced bonding. Moreover, adhesion tests confirmed an outstanding bonding between the coating and wood as well as glass, which is assumed to result from interactions between the PF's hydroxyl groups and functional groups on the substrates' surfaces. Studies on the wettability revealed a hydrophobic character of such coatings, therefore generally indicating a possible application, for example, to reduce water uptake by wooden materials.
