“…In fact, warm mixtures showed higher final cumulative axial strain and consequently a lower creep modulus (according to the results of DSR tests on binders), but they showed a lower rate of increase of permanent deformations compared to the control HMA. In this sense, conflicting results about rutting behavior of warm mix prepared with chemical tensoactive technology were also found in literature since some studies documented increased performance of WMA (Hurley and Prowell 2006;Kheradmand et al 2014) whereas other authors reported opposite results (Capitao et al 2012;Rubio et al 2012;Sanchez-Alonso et al 2013).…”

Warm Mix Asphalt (WMA) is a modified asphalt concrete, obtained by using organic, chemical or foaming additives, which can be produced and compacted at lower temperatures (100-140°C). The environmental sustainability of WMA can be enhanced with the inclusion of steel slag in substitution of natural aggregates. Given this background, this paper illustrates an experimental research aimed at characterizing WMA containing steel slag. Rheological tests were carried out on asphalt binders in order to investigate the effect of the WMA additive on high-service temperature properties. Then, the bond strength between asphalt binders and aggregates (limestone and steel slag) was investigated. Finally, compactability and permanent deformation resistance of the studied mixtures were also evaluated. Results mainly showed that, regardless the presence of steel slag, the studied additive allowed adequate mixing and compaction at lower temperatures, improving the bond strength between binder and aggregates without affecting permanent deformation resistance of asphalt mixes.

“…A higher resistance to such permanent deformation increases the fatigue life of asphalt pavements [6]. Many studies have been conducted with different test methods such as the three or four-point bending fatigue tests under controlled strain [7]- [9], the wheel-tracking tests [9], [10], and the single penetration repeated shear tests [6] to determine the fatigue life of asphalt mixtures.…”

Asphalt and concrete pavements cover a high percentage of urban area. In the summer season, the surface temperature of asphalt pavements exposed to the solar radiation increases to 60°C or more. This is one cause of the urban heat island phenomenon. In the field of road engineering, cool pavements have been constructed to decrease the surface temperature and to improve the road environment. We have previously studied the cement-based grouting material containing cement, ceramic waste powder, and natural zeolite for cool pavements. This cool material is poured into voids in porous asphalt pavements. The construction method for this cool pavement is the same as that for water retaining pavements. The temperature measurements show that the surface temperature was lower by 15-20°C than the conventional porous asphalt pavement temperature of 60°C. On the other hand, the accumulation of permanent strain in the asphalt pavements causes rutting under passing traffic loads in the hot summer season. In this study, the fatigue tests under a fixed-point load were conducted to evaluate the fatigue resistance of the surface temperature reducing pavement at 40°C. The fatigue resistance of pavements under various loading levels is evaluated at sinking displacements of 15 and 20 mm. The test results show that the surface temperature reducing pavement has a higher fatigue resistance than conventional porous asphalt pavements.

“…The previous studies indicate that the mixes produced in the foamed asphalt technology by the addition of zeolites are characterized by the fatigue resistance comparable to hot mixes and a slightly lower stiffness modulus [20,21]. Some studies also indicate the reduced water and frost resistance [22][23][24], especially when using the zeolites soaked with water, which improves the foaming effect of asphalt [25,26].…”

Application of Zeolite Tuffs as Mineral Filler in Warm Mix Asphalt

Zeolite materials are used in the warm mix asphalt technology as an asphalt foaming additive, which partially replaces the filler. This article analyzes the influence of the zeolite and other fillers addition on the properties of mastic asphalt. In the research, 35/50 penetration grade asphalt and three types of fillers were used: lime filler (L), zeolite tuff (clinoptilolite) (C), hydrated lime (H) and their mixed combinations (C:L in 1:1 and 1:3 proportions as well as C:L:H in 2:2:1 ratio). The characteristics of the materials included: chemical analysis, phase composition and particle size distribution. The following properties were determined on the asphalt mastic samples: penetration, softening point, penetration index, dynamic viscosity and stiffening measured by softening point increase. It was found that clinoptilolite could partially replace the traditional lime filler, without a negative impact on the asphalt mastic properties. Additionally, the hydrated lime inclusion should have a positive effect on the frost resistance of an asphalt mix.
