Investigation of Adding Proportion of RAP in Recycled Asphalt Mixture

According to the relationship between gradation and proportion of Reclaimed Asphalt Pavement (RAP) and design gradation of recycled mixture, the authors discussed the influence of proportion of RAP on gradation adjustment of recycled mixture. And then, recycled mixture with 0%, 30%, 50%, 70% of RAP...
