cement recycled asphalt base stabilization

Recent Development of Recycled Asphalt Pavement (RAP) Bases

Recycled asphalt pavement (RAP) has increasingly been used as a base material for highway construction as a sustainable solution. Due to the existence of asphalt, 100 % RAP typically has low strength and high potential of creep and permanent deformations.
