The Challenges of Using Reclaimed Asphalt Pavement for New ...

Reclaimed Asphalt Pavement (RAP) material mainly consists of removed asphalt concretes from existing infrastructures and, to a minor extent, of wasted or rejected mixes during the production processes. Being composed of two valuable non-renewable resources, i.e., aggregates and bituminous binder, its conscious use can ensure the sustainability of asphalt pavement construction.

The asphalt concrete removed from an existing road pavement is a fully recyclable material for construction [1,2].Since it consists of valuable non-renewable resources, i.e., approximately 95% wt. of aggregates and 5% wt. of aged bituminous binder, it can be re-used in new asphalt mixtures, reducing the demand for virgin aggregates and bitumen, or as recycled aggregates to produce unbound ...

2021 — What challenges will the asphalt industry face?

The increased use of reclaimed asphalt pavement (RAP) now challenges contractors and agencies to find a new mix design method that will reliably produce durable, long lasting pavements. The trend over the last 20 years has been one-sided — fixing the ruts at the expense of the cracks.

Problems With Recycled Asphalt Paving Hunker

Asphalt pavement production consists of mixing sand and aggregate with asphalt or bitumen. The process produces a hot, concrete mix that is laid on road surfaces. It is a common industry practice to mix in recycled asphalt paving with the new concrete mix. However, some problems could surface with the use of recycled asphalt paving.

Implementing Waste Oils with Reclaimed Asphalt Pavement

The use of reclaimed asphalt pavement will be an essential attempt to reduce the costs of aggregates and bitumen in the final mixture. On the other hand, the main challenge for implementing RAP (Reclaimed Asphalt Pavement) is to overcome quality issues. RAP doesn’t perform like a fresh pavement since it is an aged material and needs to be improved. This puts forward the requirement

Reclaimed Asphalt Pavement (RAP) is termed as removed and/or reprocessed pavement materials containing asphalt and aggregates. In consequence, asphalt pavement is generally removed either by milling or full-depth removal technique. Milling entails removal of the pavement surface or resurfacing work using a milling machine, which can remove up to 100 mm thickness in a single pass. Full-depth ...
