“…It is surprising that POFA was found to enhance rutting resistance as against its intended purpose of serving as anti-stripping agent. This finding is supported with the microstructural results from Ooi and Ismail [41] where POFA modification was found to improve the thermal resistance. Analyzing the images shows that only the HMA parade minor loss in aggregate coating, but the percentage loss is insignificant to be considered as stripping failure potential of the mix.…”

The unwanted disposal Palm Oil Fuel Ash (POFA) can be minimised through its application in road construction. Available literatures have shown that POFA improves the performance of hot mix asphalt (HMA), however, its application in warm mix asphalt (WMA) remains unexplored. This study was carried out to investigate the performance of WMA with POFA modified bitumen. In this study, Five percent POFA and 0.75% Evotherm is blended with 60/70 PEN grade bitumen to produce warm POFA modified bitumen (B3). The B3 binder is subjected Fourier Transform Infrared spectroscopy (FTIR), Atomic Force Microscopy (AFM), and Contact angle measurements to understand the effect of this modification at microstructural level. Also, the binder is used in preparing dense graded asphalt concrete (AC14) at 140/130 ℃ mixing/compaction temperatures rspectively. Mixture performance tests such as Marshall flow and stability, dynamic creep, Asphalt Pavement Analyser (APA), tensile strength ratio, and boiling water tests were used to examine the resistance of B3 binder to rutting and moisture damage. Results from dynamic creep and APA test shows that the WMA mixtures possess 30% improved rutting resistance than the conventional HMA. On the contrary, the WMA sample parade lower resistance to moisture damage by 10% as revealed by the tensile strength ratio test. All the tested samples satisfied the specification limits for AC14 mixture, thus alleviating any concern regarding the moisture damage vulnerability of WMA mixtures.

“…Recall that there are various elemental compositions such as silicon, calcium, aluminium, magnesium, potassium, etc that exist in OPA particles, which were revealed by the XRF Spectrometer. Therefore, the peaks at about 792 and 1037 cm −1 were attributed to the Si‐O bonds alternating to Al‐O bonds whereas the 874 and 1410 cm −1 suggested the presence of calcite as reported in previous work . There was a broad band in the region between 3100 and 3600 cm −1 assigned to the hydroxyl (‐OH) functional groups.…”

“…Generally, the OPA showed the unique surface characteristics, i.e. irregular shaped particle with porous structure and rough surface , which introduces better physical interaction between filler surface and rubber matrix . One of the major drawbacks of using OPA is its hydrophilic nature that causes agglomeration and poor dispersion during compounding.…”

Chemically modified Oil Palm Ash (OPA)‐filled natural rubber composites were prepared by modifying the functional group of OPA with cetyltrimethylammonium bromide (CTAB) prior to compounding by using laboratory conventional laboratory‐sized two‐roll mills. The functional groups of CTAB‐modified OPA were analyzed by using Fourier Transform Infrared (FTIR) and compared with those of non‐modified ones. The CTAB‐modified OPA‐filled NR composites showed shorter scorch time and cure time as compared to those of non‐modified OPA, which was attributed to the new functional groups occurred. The tensile test results showed that the OPA‐filled NR composites with CTAB modification exhibit improvement in tensile strength, tensile modulus, and hardness but lower elongation at break as compared to nonmodified ones. The tensile fractured surface of modified OPA filled NR composites revealed the well embedded and better distribution of CTAB‐modified OPA in NR matrix. The toluene uptake was also found to be lower for the modified OPA‐filled NR composites and showed better rubber–filler interaction; it further showed that surface modification with CTAB could compatibilize the OPA particles and NR matrix.

Se lleva a cabo una revisión de investigaciones cuyo eje de estudio son los compuestos de caucho natural reforzados con cargas obtenidas a partir de residuos pos-industriales como el almidón de patata, bagazo de caña de azúcar, aserrín, cáñamo, tallo de plátano, cáscara de semilla de tamarindo, cascarilla de arroz, sílice obtenida de la cascarilla de arroz, fibra de coco, fibra de hoja de piña, lodo de mármol y ceniza de palma de aceite. Se evalúa para cada carga su composición, métodos de obtención y tratamientos de preparación, su incorporación en la matriz polimérica, las características de vulcanización de las mezclas y las propiedades físicas, químicas, térmicas y mecánicas.
