abstract = {This study evaluates the short-term resilient behaviour of cold in-place recycled (CIR) asphalt mixtures with bitumen emulsion when they are more similar to non-cohesive granular materials than to conventional hot mixtures. Gyratory compacted CIR specimens were manufactured using different proportions of bituminous emulsion and water, and dynamic triaxial tests were conducted at different curing times. The resilient moduli were obtained experimentally and fitted using three numerical models. Characteristic nonlinear elastic behaviour and an increase in stiffness with curing time were observed. Water loss during curing and stiffness increase were found to be related. Mixtures with 2.50% residual bitumen and 2.75% added water showed the best short-term stiffness evolution.},

abstract = {Compaction is one of the most important factors to be considered while manufacturing laboratory samples of cold in-place recycled (CIR) mixtures. In this study, the effect of three laboratory compaction procedures (static, gyratory, and impact) on the volumetric performance of CIR mixtures was investigated. CIR specimens were manufactured with the same proportion of added water and bitumen emulsion, and using several levels of compaction, varying the number of gyrations and blows. The volumetric properties were evaluated by different procedures, both before and after curing. A comparison between the laboratory results of the different tests, the design target values, and actual in-field values was performed. It was observed that gyratory compaction proved to be the most versatile and one that best represented the real compaction. The bulk density procedure by dimensions was useful for laboratory design; however, it overestimated the sizes of the air void content by more than 10% compared to the field values.},

abstract = {To expand the body of knowledge regarding cold in-place recycled mixtures, this study presents two different laboratory design methods. The main differences between the methods are the compaction procedures (static and gyratory) and the required strength tests (unconfined compressive strength and indirect tensile strength). Specimens were manufactured using both methods, with different contents of bitumen emulsion and added water. The effects of adding Portland cement and increasing the compaction energy were also investigated. The compliance with strength criteria was reviewed, and the optimal bitumen emulsion and water contents were identified. The requirements of the specification based on gyratory compaction proved to be excessively high. A reduction of the values is suggested, and further research is encouraged to allow new benchmarks to be set.},

abstract = {Liquid waste containing lignin, a biopolymer of vegetable origin, is generated from the production of wood hardboards. Because polymers improve the performance of asphalt mixtures, this work studies the possibility of using this industrial waste as a bitumen extender in the production of asphalt mixtures. Thus, asphalt mixtures with 0% (control), 5%, 10%, 20%, and 40% of industrial waste were produced. The bitumen–aggregate adhesion, moisture damage resistance, resilient modulus, permanent deformation resistance, and thermal susceptibility of such mixtures were analysed. Asphalt mixtures with 20% of industrial waste showed the best moisture damage resistance. As the percentage of industrial waste increased, the thermal susceptibility of the mixture also increased. In this regard, at 5 °C, the resilient modulus of the mixture made with 20% of industrial waste was 19.08% lower than that of the control mixture. Moreover, at 30 °C, the resilient modulus of the mixture made with 20% of industrial waste was 10.48% higher than that of the control mixture. Therefore, it can be stated that it is appropriate to use this industrial waste containing lignin as a bitumen extender. It can be used in asphalt mixtures for road pavement, mainly by substituting 20% of the bitumen by this liquid waste. It reduces the consumption of bitumen and improves the performance of asphalt mixtures, contributing to the purpose of sustainable construction. The industrial waste was not subjected to any transformation process, thus facilitating its use. The reduction in the use of bitumen in asphalt mixtures by adding this industrial waste contributes to the goals of sustainable development and cleaner production of asphalt mixtures.},
