While the research and development of the SUPERPAVE asphalt mixture design and analysis system did address the use of polymer modified asphalt binders in the specification of material performance properties, no recommendations or procedural guidelines were given for the use of recycled materials. The use of recycled asphalt pavements (RAP) in new paving mixtures is not an innovative idea. RAP has been called one of the most recycled materials in the world, and its use in paving mixtures has been shown to have environmental, economic and performance benefits. In this study, four different RAP stockpiles were sampled and the characteristics of each RAP material were investigated in terms of binder content, aggregate gradation and the rheologic characteristics of the reclaimed RAP binder. The reclaimed RAP binders were blended with several different virgin performance graded binders in order to determine how RAP binder concentration affected the stiffness and performance grade of the RAP -- virgin binder blends. Recommendations were made on how to select virgin binder grade andor RAP concentration combinations to fulfill a project's binder grading requirements. The effects of RAP were also investigated in terms mixture design, and recommendations were made with regards to material handling and specimen fabrication procedures. Asphalt concrete mixtures containing RAP were characterized in terms of stiffness and resistance to plastic strain using SUPERPAVE testing methods, and the results of these tests were compared to those of virgin material mixtures. Assuming a simulated pavement cross section and traffic loading, the results of this performance testing were used in performance prediction models to estimate how pavements constructed with RAP would perform compared to those made from 100% virgin materials. The predicted performance of pavements containing up to 40% RAP (by weight) was found to be similar or slightly better than that of virgin material pavements.

This volume includes a collection of research and practical papers from an international research and technology activities on recent developments in pavement design, modeling and performance, and effects on infrastructure, green energy, technology and integration. Sustainability is increasingly a key priority in engineering practices. With the aging transportation infrastructure and renewed emphasis on infrastructure renovation by transportation agencies, innovations are urgently needed to develop materials, designs, and practices to ensure the sustainability of transportation infrastructure. The volume is based on the best contributions to the 2nd GeoMEast International Congress and Exhibition on Sustainable Civil Infrastructures, Egypt 2018 – The official international congress of the Soil-Structure Interaction Group in Egypt (SSIGE).

Bachelor Thesis from the year 2019 in the subject Engineering - Civil Engineering, grade: 3.0, University of Mauritius, language: English, abstract: This study is a Life Cycle Assessment which shows the implementation of RAP in HMA design compared to the conventional pavement in Mauritius. Firstly, a thorough literature review was carried out which was supported by interviews from contractors and local authorities about the use of RAP and its implementation in the local context. The information concerning the use of HMA and its construction practices in Mauritius were obtained from local authorities through specifications. The data for RAP was obtained through literature as its practice in Mauritius is still not implemented. After processing the data, the software SimaPro was used to model both systems with a functional unit of 1 km and 4 m for the width of the single lane. Consequently, design 1 was modelled as conventional HMA and design 2 showed the use of 10 % of RAP in the wearing course with a system boundary consisting of the raw material acquisition, raw material processing, the construction, maintenance and the end of life phase but excluding the operation/use phase. The ReCiPE indicator was then used for the impact assessment which consists of the midpoint and endpoint indicators.

Asphalt concrete pavements receive maintenance to retard the loss of structural integrity and functionality. A common maintenance action to address localized failures is hot mix asphalt or cold mix patches. The result of this practice is a pavement cross-section with different binder ages. The main focus of this study is to investigate the effects of different binder ages in reclaimed material included in cement stabilized bases resulting from full depth reclamation of asphalt concrete roads. The research hypothesis for this thesis is that the new asphalt binder from hot mix patches in an aged flexible pavement has no significant effect on the stiffness properties of a cement stabilized base which has been placed using full depth reclamation. Three types of material were used in this study. The first was virgin aggregate base (AB), the second was Full Depth Reclaimed Material (FDRM) which consisted of 50% rubberized reclaimed asphalt pavement and 50% virgin aggregate base, and lastly 90% Reclaimed Asphalt Pavement (RAP) with 10% virgin aggregate base. A portion of the full depth reclaimed material and a portion of the RAP were oven aged to simulate aging in the field. The material was then stabilized with 5% cement. The tests that were conducted included maximum dry density, optimum moisture content, unconfined compressive strength, indirect tensile strength, dynamic modulus and shrinkage.The main conclusions of this study were that unaged asphaltic material in full depth reclaimed bases stabilized with cement will have a lower dynamic modulus compared to cement stabilized material made from the surrounding, aged asphaltic material. The strength properties between the aged and unaged RAP and FDRM were not significantly different. This suggests that compressive and tensile strength depends primarily on the cementitious bonds, and that the age of the asphalt binder covering the aggregates does not influence the strength. Even though this will not influence the mix design of the cement stabilized base constructed with full depth reclamation, the base will have reduced stiffnesses in localized areas which are potential fatigue failure zones for the AC surface.
