“…However, this negative effect can be reduced by replacing limestone powder with 75% PF. The results suggested that using PF as filler might negatively affect the low-temperature performance of the corresponding asphalt mixture [ 31 ].…”

This study introduced phosphogypsum coupled with steel slag powder to prepare the phosphogypsum based filler (PF) for asphalt mixture. Penetration, penetration index, softening point, ductility, equivalent softening point, moisture stability of asphalt mortars with different steel slag powder content, filler-asphalt ratio, and PF content were studied. Mechanical properties of PF based asphalt mortar (P-AM) were then analyzed to determine the optimum steel slag content in PF. Overall desirability method was used to determine the optimum replacement ratio of PF content in limestone filler. Rheological properties of P-AM were also analyzed through dynamic shear rheometer. Volumetric performance, high-temperature performance, low-temperature performance, and moisture stability tests were carried out on PF based AC-20 asphalt mixture. Results showed that P-AM presented the optimum performance when the content of steel slag powder was 23% by mass of phosphogypsum. Fatigue and rutting factor of asphalt mortar were enhanced by PF. The optimum PF content in replacing limestone filler was 75% through overall desirability evaluation. PF developed the high-temperature performance and moisture stability of asphalt mixture. Additionally, volumetric and low-temperature performance were not significantly affected by PF. It is suggested that using PF which is based on phosphogypsum as a filler of asphalt mixture to partially replace traditional limestone filler was adequate.

“…Filler fills the voids between the aggregate grains and the pores within the aggregates themselves. Filler requirements, according to the Ministry of Public Works, Directorate General of Highways in 2010 must be dry, free from lumps, and generally considered to be that portion of the mineral material that can pass through a 0.075 mm sieve [20]. Based on these provisions, filler often uses cement in field applications because it contains 60-65% quicklime, silica 20-24%, and alumina of about 4-8%.…”

Road quality is also affected by temperature and weather, leading to surface pavement deformation. It is necessary to improve the quality of the road pavement so that the quality of the road becomes more durable and stable. Hot Rolled Sheet – Wearing Course (HRS-WC) is flexible and has high durability. The natural mineral has been used as the filler for pavement construction. However, further research is necessary to obtain alternative and more sustainable materials. This study will discuss portland cement filler as a reference to compare filler replacement with chitosan powder (shellfish) based on the general specifications of the 2018 highway revision 3 division 6. Chitosan powder contains calcium oxide of 3.04% and silica oxide of 17.98%, which are similar to cement fillers. The composition of chitosan powder are 100%: 0%, 50%: 50%, 25%: 75%, and 0%: 100%. performance analysis is done through the marshall test. The results showed that the comparison of the use of the best chitosan powder was at the asphalt content of 7.3 with 50% : 50% with a marshall test value of 993.4 kg, flow 3.20 %, VMA 18.36%, VFB 72.01%, VIM 5.14, MQ 301.440 kg/mm. From the result which meets the requirement, the filler has shown quality improvement as an additional mixture according to (SNI 03-6723-2002). Hence still not optimal to replace portland cement because, from the value of the marshall test, portland cement has a higher marshall value than chitosan.

“…The filler and the binder form the asphalt mastic, which allows the actual agglomeration of the larger aggregates [14]. This matrix is relevant due to the dispersion of the filler in the binder matrix and the interaction it achieves in the microstructure of the porous asphalt [15]. Some studies have pointed out that water damage in asphalt mixes directly relates to the filler/binder interface.…”

Styrene–butadiene–styrene copolymer (SBS) can be used to improve the mechanical and deformation properties of the binder used in its manufacture. However, the high cost of and variability in processing limit its performance. A secondary modifier to solve these problems is nano- and micromaterials that allow for the generation of unique properties in polymeric systems. Based on this, this study experimented with fly ash micro-filler (μFA) in low proportions as a binder modifier with SBS for use in PA mixes. The FA residue is considered in 3% and 5% dosages on a base binder with 5% SBS. Rheological results show that μFA improves classical, linear viscoelastic (LVE), and progressive damage properties compared with the modified binder. The PA blends with μFA reduce binder runout, resulting in a thicker film, thus showing better abrasion resistance in dry and wet conditions. Samples with μFA increase the post-cracking energy in indirect tension due to higher ductility. However, they decrease the fracture energy due to higher cracking before failure. In addition, μFA manages to decrease the difference between dry and wet ITS.
