“…The values for all volumetric properties of 30-PKS are higher than those of 0-PKS. Based on previous research, the results at 30-PKS meets the right criteria which had provided in Asphalt Institute Standard Specification and also the replacement between 10-PKS to 30-PKS by weight coarse aggregate can be used for medium traffic road [12]. According to Ndoke (2014) [11], aggregate replacement with 10-PKS is suitable for heavy-traffic roads.…”

“…10% PKS was used as a partial coarse aggregates replacement for heavily trafficked roads, and 50% PKS was used for light-traffic roads. A study conducted by [12] investigate the effect of replacing 30% coarse aggregates with PKS following the Standard Specification of the Asphalt Institute. Graded PKS in varying amounts of between 10%-30% by weight of coarse aggregate can be used as a replacement for medium-trafficked roads, and 100% replacement is possible for lightly trafficked rural roads.…”

Pavement failures such as fatigue, rutting, cracking, bleeding, and stripping are typical pavement deterioration. Researchers have been experimenting with pavement modification to overcome these problems. This study determines the optimum binder content (OBC) for modifying an asphalt mixture with a partial replacement of coarse aggregate (5mm-14mm sieve size) with palm kernel shell (PKS). A 60/70 penetration grade bitumen was mixed with 10, 20 and 30% PKS at selected aggregate gradation following the Public Work Department of Malaysia (JKR/SPJ/2008-S4) specification. The preparation of 60 samples of unmodified and modified asphalt mixture employed the Marshall Method compacted with 75 blows. The OBC was determined based on five volumetric properties of asphalt mixture namely stability, flow, bulk density, void filled with asphalt, and void in total mix. The OBC and volumetric properties of the modified PKS asphalt mixture samples were compared with unmodified asphalt mixture samples in accordance to the specification. Results showed that the OBC sample with 30% aggregate replacement produced the highest OBC value of 5.53% relative to the control sample with 5.40% OBC. The trend for OBC with PKS replacement begins with 10% PKS with 5.30% OBC, 20% PKS with 5.32% OBC and 30% PKS. All volumetric properties of the PKS samples are within the specification limit. Thus, PKS has a promising potential as a coarse aggregate replacement in asphalt mixture.

“…While 56.6% of the variations observed in Va values were accounted for by percent CN-PKS replacement, about 87.7% of the variations in flow values were being accounted for by percent CN-PKS replacement (Figure 4b). The low air voids recorded at 5%, and 15% coarse and filler replacement (with values 2.42 and 1.87 respectively) shows that utilizing PKS & CN-PKS at this proportion will most likely cause rutting and bleeding of the flexible pavement because there will not be enough air voids for the bitumen to occupy during traffic loading (Olutaiwo and Owolabi, 2015).…”

“…However, at 5%, and 15% of the replacement, the percent air void is very low about 2.42% and 1.87% (Table 4) respectively. Utilizing this replacement at this proportion will most likely cause rutting and bleeding of the flexible pavement because there will not be enough air voids for the bitumen to occupy during traffic loading [14].…”

This study investigated the influence of palm kernel shell (PKS) and its calcined nanomaterial (CN-PKS) as aggregates on the volumetric and Marshall Properties of hot mix asphalt concrete. The PKS and CN-PKS were used to replace the coarse aggregates and the filler material at 5, 10, 15, 20 and 25 % each in the same asphalt mix in three replicates. The compositions were mixed together and compacted with 50 blows on both sides to obtain cylindrical samples for the Marshall Stability tests. Volumetric parameters (density, air void, voids filled with bitumen, marshal stability and flow) were carried out on asphalt cores to evaluate the strength of the mixes. Mean values were presented for the tested parameters. All the percent of PKS and CN-PKS mix proportions are within the limits of specification. The optimum stability and percentage air void value was recorded at 20%. Utilizing PKS and CN-PKS at 5% and 15% will most likely cause rutting and bleeding of the flexible pavement due to low percent air void. This study concluded that partial replacement with PKS and CN-PKS as coarse and filler at 20% in the same hot mixed asphalt can improve the properties of asphalt concrete for use in medium traffic roads
