Aggregate production dates back to the Roman Empire, and it has been critical to the growth of our world ever since. Essentially, they are the most basic material used in construction. They provide the foundation for roads, bridges, and buildings, while also making up over 90% of an asphalt pavement and up to 80% of a concrete mix.
Monitoring and optimizing the surface roughness of high …
Compared with the abrasion process which usually reduces the pavement roughness, the aggregate exposure process will increase the roughness of pavement, so it can be regarded as the process opposite to the abrasion process. In summary, the 3D parameters should be useful to evaluate the evolution of the surface roughness in the EACCP exposure ...
Influence of Natural Aggregate Crushing Process on Crushing
The aggregate crushing process was carried out for 4–8 mm and 10–14 mm fractions using cone crushers of the 1044 type. Aggregate crushing was carried out in a Los Angeles drum, in accordance with the requirements of EN 1097-2:2020. The analysis showed that for grits of the 10–14 mm fraction, the lower values of the LA indices were ...

Effects of moisture damage on asphalt mixtures
The aggregate chips are pressed or rolled into the surface of the bitumen and then the plate is immersed in water for a specific time. The adhesion of the aggregate chips is determined by blows to the back of the plate. The evaluation is made depending on the proportion of aggregate chips that still adhere to the bitumen (Solaimanian et al., 2003).
