Feasibility study on recycled vegetable oil waste and recycled polyethylene for the modification of aged asphalt

Use of Recycled and Waste Fibers in Asphalt Concrete

A significant problem associated with asphalt concrete mixtures is the lack of durability resulting from an inadequate asphalt cement content. Additional asphalt cement added to increase durability results in flushing, bleeding and a significant loss In stability. Fibers have been used in stone matrix asphalt and open-graded friction course pavements successfully throughout Europe to allow high...

Modification of the Properties of Warm Mix Asphalt Using Recycled Plastic Bottles

Construction of flexible pavements with hot mix asphalt (HMA) mixtures consumes huge energy which impacts the resources and the environment of the world. Warm Mix Asphalt (WMA) is an effective alternative as they produced with lower mixing and compaction temperature than those used in HMA production. This technology decreases energy consumption, saves money, and reducing the environmental pollu...

Effects of Recycled Concrete Aggregates on Properties of Asphalt Concrete

Aging effects on recycled WMA porous asphalt mixtures

Nowadays, the use of reclaimed asphalt pavements (RAP) is often combined with Warm Mix Asphalt (WMA) technologies with several benefits in terms of environment, cost and mechanical performance. Concerns still exist related to in-service and aging characteristics of warm recycled mixtures since WMA technologies have been developed over the last decade and hence long term performance data are not...
