Gap - graded asphalt (MNU) has high resistance to the traffic, however, due to its specific grading it is more prone to a destructive effect of the climatic factors compared to other bituminous mixes. In order to ensure its durability, the mixture was modified with the use of the SBS polymer and hydrated lime. Asphalt was modified with the addition of 2, 4, 6, 8 % of the SBS polymer, while hydrated lime was dispensed in the filler in the amounts 10, 20, 30, 40 and 50 %. The performed research into the resistance of MNU to high and low temperatures as well as to water and frost showed a positive impact of the two modifiers on the durability and high mechanical properties of MNU.
