ABSTRACT
Reclaimed asphalt pavement (RAP) is removed using a milling machine that grinds the asphalt into small pieces and is a useful alternative to virgin materials as it reduces the use of virgin aggregate. The base course is a layer that comes below the surface layer of an asphalt pavement and consists of gravel material with lower specifications than the surface layer. Recycled asphalt pavement (RAP) is increasingly being used as the base material for highway construction as a sustainable solution. Due to the existence of asphalt, 100% RAP usually has low strength and high potential for creep and permanent deformations. RAP can be mixed with virgin aggregate, stabilized by cement to increase its strength and reduce its creep and permanent deformations. A good road network is the key to the rapid development of a country’s economy. Gradually increase the percentage of cement in the mix (2, 4 and 6%) as shown in Tables 4 to 6 and it satisfies all the values of Tables 4 to 6 for Requirement for WMM- grading (table 400-II) of MORTH revision 4.
