Cement Stabilization of Reclaimed Asphalt Pavement

Cement Stabilization of Reclaimed Asphalt Pavement

About this site

Jun 03, 2002  A pavement design analysis of using various cement stabilized RAP-virgin aggregate mixtures as base materials was also undertaken. Results indicate that the optimum moisture content, maximum dry density, and strength of RAP will generally increase with the addition of virgin aggregate and cement.
