“…In any case, only a small quantity of HL and SSA fillers are necessary to fabricate the mixes. In the case of the HL filler, only approximately 1% by weight is necessary, which is in agreement with the values stated by some previous authors (1-2% of lime in the mix) (Akili 1993;Sengul et al 2012).…”

In this study, the behavior of bituminous mixes made with sewage sludge ash (SSA) as mineral filler was investigated. The 4 behavior of these mixes was evaluated with the Cantabro, indirect tensile strength, water sensitivity, permanent deformation, and resilient 5 modulus tests. The results show that SSA waste may be used in bituminous mixes at approximately 2-3% weight percent, maintaining 6 adequate levels of cohesion and adhesion in the mixtures, which is comparable to mixtures made with active fillers such as hydrated lime 7 and cement. Moreover, its use does not increase permanent deformations. However, the resilient modulus test gave slightly lower results for 8 mixes made with SSA than for mixtures made with other fillers. It may be concluded that SSA waste may be used as a filler for bituminous 9 mixes with better results than for mixes made with limestone fillers and with similar results for mixes made with other fillers such as hydrated 10 lime and cement.

“…Besides, this finding is confirmed by many studies' conclusions that have illustrated; hydrated lime in asphalt mixtures can reduce the permanent deformation (rutting) of the pavement because of its distinct stiffening effects, moisture-associated damage by enhancing the aggregate-asphalt bonding, and long-term oxidative aging possibility [38,39]. In addition to its capability to resist micro-crack development within the mix [39]. Tarrer also found that hydrated lime reacted with silica and alumina aggregates in a pozzolanic manner that added considerable strength to the mixture [25].…”

“…As previously reported, HL results in an increase in the HMA mixture's stiffness, bitumen softening point, and bitumen mastic [12,25].

This research is conducted to evaluate the influence of mineral filler on the volumetric properties, mechanical and field performance of Hot Mix Asphalt (HMA). Two mineral filler types, namely, Hydrated Lime (HL) and Dust Plant (DPt) were used. Three filler proportions were utilized greater than 1% which represents the most applicable percentage, especially for HL, used by the Ministry of Transportation Ontario (MTO). The effect of filler on various volumetric properties including Voids In Mineral Aggregates (VMA), Voids Filled With Asphalt (VFA), dust to binder ratio (Dp) is examined. Mechanical and predicted field performance of HMA to the best filler proportion that meets all the MTO limitations is also investigated. The obtained results indicated that the Optimum Asphalt Content (OAC), VMA, and VFA decrease as the filler content is increased. HMA mixtures that includes DPt filler had the higher values of VMA, VFA, and OAC compared to the hydrated lime. The addition of filler with 2.5% percentage is very successful for both filler types due to satisfying all MTO requirements for volumetric properties of HMA. Based on MTO specifications, the addition of 2.0% filler seems to be unsuccessful for both filler types due to lowering the Dp ratio. Mix design with 3.0% filler was also unsuccessful because of the lower value of OAC meaning that the mix is dry and there is insufficient asphalt binder to coat the aggregate particles. Besides, filler type has a significant effect on the mechanical properties of the HMA mixtures. As a filler in HMA mixtures, the utilization of HL as a portion of 2.5 % leads to a significant improvement in mixture resistance to water and freezing and thawing. The mixtures that included HL have a higher cracking resistance, greater stiffness, and a higher fracture stress than the mixtures that included DPt. Furthermore, predicted field performance indicated better outcomes for mixes with HL compared to DPt mixes. Doi: 10.28991/cej-2020-03091619 Full Text: PDF

“…A mixture with a higher MQ is stiffer and believed to be more resistant against permanent deformation. However, comparing the MQ results with those of dynamic creep tests for hydrated lime and polymer modified asphalt concrete, Sengul et al found that MQ is not a good indicator of resistance against permanent deformation [29]. Same results was found by Tayfur et al [30] for SMA mixtures modified with polymer.…”

Scrap tires and plastics are among the main solid wastes generated in large amount throughout the world. Polyethylene Terephthalate (PET) is the most consumed and wasted plastic. In this study the effects of PET particles size and content on some engineering properties of asphalt concrete containing rubber modified asphalt has been investigated. Different concentrations of waste PET including, 0, 2, 4, 6, 8 and 10% (by the weight of binder) in two different ranges of size were to asphalt concrete and the Marshall stability, Marshall quotient, indirect tensile strength (ITS) and uniaxial dynamic creep properties were evaluated. Results show that the Marshall stability and Marshall quotient increase with increasing PET content. The indirect tensile strength (ITS) test results show that the highest ITS is obtained by adding 2% of PET into the mixtures and beyond that the ITS decreases with increasing PET content. Dynamic creep test results revealed that the resistance against permanent deformation decreases with increasing PET content. However, the mixture containing fine graded PET particles has more resistance against permanent deformation than the mixture containing coarse graded PET particles. Comparing the results on the rubber modified mixtures in this research with those on conventional mixtures accomplished previously reveals that the trend is different.
