Palm oil fuel ash application in cold mix dense-graded bituminous mixture

The performance of cold mix cold-laid emulsified asphalt mixtures is often improved by additives like rice husk ash, fly ash, fibres, and lime for varying applications. High void content, weak early strength, and slow rate of strength gain remain an unsolved challenge for cold mixtures. This study explored the feasibility of utilising palm oil fuel ash (POFA) in a fast-curing cold mix asphalt (CMA) as a filler replacement. Large volumes of POFA...
