Abstract. Cold In-place Recycling (CIR) is a rehabilitation treatment that restores a flexible pavement structure. While there has been significant re-search in design and performance testing of CIR, there is limited considera-tion of performance during construction. This research validated the Stiff-ness Raveling Mechanism Test (SRMT) in the lab and in the field, as an in-expensive, easy...
Abstract. Cold recycling is a technology used in constructing or rehabilitating flexible pavements. It strives to optimise the performance of processed reclaimed materials and construction methods, in order to gain environmental and economic benefits i.e. reducing carbon footprint whilst improving pavement life. The technology leads to the production of Bitumen Stabilised Materials (BSMs), a...
Abstract. A summary of literature on performance testing of Full Depth Reclamation (FDR, also known as Bitumen Stabilization) is presented in this paper. FDR is an important pavement rehabilitation treatment that can eliminate severe distresses and improve pavement structure, while using environmentally friendly techniques. FDR can be considered a semi-bound material (when stabilized with...
Abstract. Globally, transportation agencies are adopting reclamation and recycling strategies for their rehabilitation and construction needs. Cold recycling technologies are regarded as a sustainable approach for rehabil-itating flexible pavements, primarily due to their economic and envi-ronmental benefits. Cold in-place recycling (CIR) as one method in-volves reclaiming a portion of the...
Abstract. This study explores the industrial-scale production and applica-tion of asphalt mixtures incorporating high rates of recycled concrete aggre-gates (RCA), steel slag aggregates (SSA), and reclaimed asphalt (RA). With a dedicated focus on sustainability within road construction, the investiga-tion scrutinizes two specific asphalt mixtures through a comprehensive field trial section....
Abstract. The maintenance and rehabilitation of road pavements consume high annual budgets from road administrations, are associated with a huge production of waste, and consequently a large use of natural resources. In this way, the multi-recycling of reclaimed asphalt pavement (RAP) presents itself as a solution to part of the problem, thus avoiding its classification as waste and...
