| 摘要： | The increasing demand from road traffic requires continued construction and improvement of roads in both urban and rural areas. The pavement construction industry is one of the largest economic and material consuming industries in the world. The construction of a new pavement or overlays involves a huge consumption of aggregate and binder. This increasing demand has resulted in growing costs and scarcity of natural materials and increase in construction and demolition wastes, which further causes waste disposal problems. Thus, there is a need to look for alternate pavement design for new construction and maintenance. The use of Reclaimed Asphalt Pavement (RAP) in roadway construction fits with the overall objective of sustainable development by the careful use of natural resources. Large quantities of Reclaimed Asphalt Pavement (RAP) materials are produced during highway maintenance and construction. RAP recycling activates reduces the use of declining virgin aggregates and tackles the issues of material storage and disposal of reclaimed asphalt material generated from pavement construction. Further, energy savings can also be done through the use of RAP in roadway construction by reducing the processing and transport of virgin aggregate. India has very limited experience with recycling and reuse of RAP in various layers of pavement structure. The main objective of the present paper is to evaluate the mechanical properties of reclaimed aggregates so as to analyze the suitability of its usage in flexible pavement. It was observed that the use of reclaimed aggregates (100％) and replacing some percentage of VG30 with CRMB 55 resulted in the increase of Marshall Stability, Flow value and Bulk density of Bituminous Concrete Mix. |
