Reflective crack and shrinkage cracks caused by the temperature variation and dry shrinkage of semi-rigid base materials lead to the early damage of asphalt pavement throughout the entire service life, which has attracted the wide attention of many scholars [1]. ... The graded crushed stone is a kind of unbound loose granular material, the ...

Rational compositions of crushed stone-mastic asphalt mix with the addition of fiber from fly ash from thermal power plants have been developed. A distinctive feature of the compositions of crushed stone-mastic asphalt concrete mixtures is the use of fiber additives in the amount of 4.0–5.0% of the mass of the mineral material.

Improved Weather Resistance. Crusher run stands up better to precipitation and temperature swings than gravel alone. The crushed stone content provides enhanced freeze-thaw resistance compared to sand or dirt. However, adequate drainage is still important to limit frost heaving in cold climates.
