Cold Recycling of Reclaimed Asphalt Pavements
2018Pavement engineers have in front of them multiple challenges linked to addressing issues related to social development and society’s expanding needs. One of the most substantial of these issues is perhaps how to effectively rehabilitate and/or maintain the existing road network while preserving and sustaining limited natural resources.

Creep of compacted recycled asphalt pavement
Canadian Geotechnical Journal, 2007Recycled asphalt pavement (RAP) can be beneficially used as fill in the construction of earth structures such as embankments and retaining structures. Experiments were conducted to evaluate the creep response of compacted RAP under sustained deviatoric stresses.

Recycling Dredged Sludge in Asphalt Pavement
Journal of Materials in Civil Engineering, 2014An experimental investigation of an innovative recycling method to reuse dredged sludge in asphalt pavements is presented. According to this method, semifinished products or agglomerates, made of dried sludge and bitumen, are produced. These products may be used to partially substitute fine sand and bitumen in the asphalt mix.

The development of recycling agent for asphalt pavement
Journal of Wuhan University of Technology-Mater. Sci. Ed., 2002A type of recycling agent was developed and its use for modifying used asphalt is described. The results show that the viscosity and three main properties of the aged asphalt were remarkably improved. With 5%–7% content of recycling agent, the main properties of recycled asphalt comported with China GB asphalt standard AH—70 and the recycled asphalt ...

Changes of asphalt fumes in hot-mix asphalt pavement recycling
Journal of Cleaner Production, 2020Abstract Hot-mix asphalt pavement recycling is widely practiced for its economic and environmental benefits. Existing studies are mainly focused on the engineering properties of reclaimed asphalt pavement (RAP) materials, without considering their impacts on the generated asphalt fumes—a widely recognized environmental hazard.

Decision Strategy for Asphalt Pavement Recycling
Transportation Engineering Journal of ASCE, 1982A decision model that uses utility theory to the decision making process in selecting optimum techniques for asphalt pavement recycling is presented. The model requires the identification of all the quantitative and qualitative decision criteria and the determination of a utility function for each decision criterion.
