RECYCLING OF BITUMINOUS PAVEMENTS ON THE ROAD

The recycling of bituminous pavements on the road is less expensive than removal and plant recycling. There is also less interference with traffic; however, it is not as flexible as plant recycling, and additional aggregate cannot be added. This paper discusses the procedures used in on the road recycling of bituminous pavements, and provides an overview of the advantages and

RECYCLING OF BITUMINOUS PAVEMENTS James L. M cKinney Graduate Research Instructor Purdue University INTRODUCTION The major material utilized in the construction of the roads, streets and highways of this country is asphalt. Of the nation’s 3.84 million miles of roads, 1.86 million are paved, hard-surfaced structures. 1.74 million or 94% of these paved roads are constructed of asphalt

RECYCLING OF BITUMINOUS PAVEMENTS ON THE ROAD

Complete recycling involves removal of the pavement, crushing, and adding asphalt and/or an asphaltic modifier together with new aggregate. The mixture is then heated and relayed. Surface recycling involves heater scarification, the addition of an asphaltic modifier, and rolling. The recycling of bituminous pavements on the road is less ...

Bituminous pavement recycling

The bituminous pavement rehabilitation alternatives are mainly overlaying, recycling and reconstruction. In the recycling process the material from deteriorated pavement, known as reclaimed asphalt pavement (RAP), is partially or fully reused in fresh construction. Some of the advantages associated with pavement recycling are (i) less user delay (ii) conservation of energy (iii)

Recycling Bitumen from Dismantled Road-A Case Study – IJERT

29/06/2020  Cost of construction of bituminous concrete layer of 100 meter length, 7.5 meter wide and 4 cm thick (quantity 30 m3) is Rs 246780 only, while recycled dismantled road cost is Rs 74893. Thus a saving of around 70% is observed in cost incurred when recycled bitumen is used as a partial substitute of fresh concrete.

On a low volume road, a CIR process may be suitable for a surface course if a treatment such as a fog seal is applied on top of the recycled mix. For higher volume roads, the recycled pavement should be treated as a stabilized base and a thin asphalt overlay placed on top. Generally, most applications will require a wearing course of some type.
