asphalt binder

Asphalt mixture is a general term for asphalt modified asphalt materials (including additional additives,modifications, etc.), which connect mineral particles into a whole, increase the strength and resistance of the pavement, and ensure the water resistance of the pavement.

Equipment materials

Aggregate is a general term for mineral material particles in asphalt pavement, skeleton and filler in the pavement. Sometimes, the particle size composition requires several coarse and fine mixtures. In the skeleton, particles with a diameter greater than 5 mm are called coarse aggregates, and particles with a diameter of 5 mm and below are called fine aggregates. According to the different sources, materials can be divided into two categories: natural and artificial. Natural aggregate crushed stone, gravel, sand, gravel, etc. d.; artificial aggregate consists of bauxite, stable solid metallurgical slag, etc. d. Asphalt road clothing should remove dirt, coarse aggregate should be close to cubes, polygons and facets, and its modified asphalt compressive strength should not be less than 60MPa.

Filler and asphalt material should have excellent bonding, not easy to be corroded and peeled off by water, such as poor bonding between charge and asphalt, and should be improved with useful antioxidants. When selecting and batching fillers, lamination casting should be evenly distributed between adjacent layers of different particle sizes; the stirring charge often needs to be composed of standard particle sizes, and such aggregates can also be mixed with different fractions in proportion.

Mineral powder

Mineral particles smaller than 0.074 mm. Asphalt concrete and asphalt concrete gravel pavement, its role in filling air, avoiding hot asphalt activity, viscosity and heat resistance of traveling asphalt materials. Mineral powder must also have an excellent bond (ie bond) with the bitumen to resist corrosion by water. Usually the mineral powder is limestone.If you have any other questions, please contact us for modified asphalt details or contact us directly.
