The effect of filler type on the hot mix asphalt behavior

الملخص EN

The test have been done on many samples of Hot Mix Asphalt using many types fillers like Portland Cement, Limestone, Hydrated Lime as a filler, 1% Hydrated Lime added to conventional mixture, Portland Cement introduced in cold state, and passing sieve no.200 dust (conventional mixture).

In this research, Marshall test procedure is used to investigate the potential prospects to enhance Hot Mix Asphalt properties.

The objectives also include determining which one of the additives is better than the others to be used and the method of introducing this filler type to the mixture.

According to the results, we found out that the better filler affects the mechanical properties of Hot Mix Asphalt is Portland cement when it introduced with the aggregate at the mix temperature.
