The invention relates to an improved asphalt mixture with waste grit from the process of sanding ship hulls and with polypropylene microplastics, the so-obtained asphalt mixture having improved mechanical resistance and resistance to wear, as compared to the standard asphalt mixture. The asphalt mixture consists of 33.5% crushed siliceous stone chipping with a granulation 4-8 mm, 25% crushed sand with a granulation between 0-4 mm, 25% waste grit with a granulation between 0-2 mm, 10% sort limestone filler with a granulation between 0.063-0.100 mm, 6.2% 50/70-type road bitumen and 0.3% polypropylene-based microplastics with a granulation similar to waste grit particles.
