Abstract— This paper states the application of regeneration 1) In the base, broken and pressed materials squeeze each
technology of old cement pavement materials. The size of broken other to get material layer whose density is very high, so it can
stones is analyzed and a reasonable size range is proposed. provide higher structure intensity.
Modulus and deflection of pressed granular layer are studied.
Pressing and opening traffic can enhance the bearing capacity. 2) The base can absorb strain energy which is released by
Physical character of recycled aggregate are studied. Then, the crack in lower layers, so as to achieve the purpose of resistance
use performance is evaluated. to reflection crack.
3) It has high porosity to make the use of drainage base,
