Summary:With development of production processes in refineries production of bitumen is decreasing, as well as the quality of produced bitumen. On the market this brings increased demand for bitumen accompanied by the demand for additives to improve such low quality bitumen. Many different types of additives are used, but most commonly SBS is added. Usage of additives bring additional direct costs, due to market price of additives and indirect cost due to adjustments in the technological process as such as additional mixing device in bitumen tanks, elevated temperature of asphalt or prolongation in mixing time. A topic of our research was development low price asphalt additive from waste poly-methyl methacrylate filled with a fine dispersion aluminium trihydrate (PMMA/ATH). Additionally with paraffin wax it was used as modifying agents for 70/100 paving grade bitumen. With regard to performance of modified asphalt mixtures, it was found that both additives considerably reduce moisture susceptibility and formation of ruts. With laboratory tests and field trial we found that combined technology PMA (polymer modified asphalt) and WMA (warm mix asphalt) technologies resulted in optimized production and excellent performance of pavement material.
