Environmental feasibility and implications in using recycled construction and demolition waste aggregates in road construction based on leaching and life cycle assessment – A state-of-the-art review

Cleaner Materials, Год журнала: 2024, Номер 12, С. 100239 - 100239

Due to rapid population growth and urbanization, construction activities have increased worldwide resulting in generation of enormous volume demolition (C&D) waste. On one hand, C&D waste is generated during the construction, destruction, rehabilitation existing structures. While on other, transportation sector consumes large volumes aggregates for pavement maintenance. The extraction finite natural causes potential damage environment. Recycled waste, once converted into recycled aggregates, has be utilized layers due its sound quality composition; also lowering landfill loads. This review article critically summarizes environmental risks regarding chemical composition leaching behavior wastes pavements. Additionally, this evaluates impacts aggregate production application pavements using life cycle assessment (LCA). Overall, aim study investigate benefits enable highway administrations adopt promote use development sustainable road infrastructure. In way, attempts a new era achieve net zero goal.

Influence of fiber-asphalt interface property on crack resistance of asphalt mixture

Case Studies in Construction Materials, Год журнала: 2022, Номер 17, С. e01703 - e01703

Опубликована: Ноя. 23, 2022

This paper aims to analyze the interface property between fibers and asphalt, study its influence on crack resistance of asphalt mixture. Four (basalt fiber A (BF-A), basalt B (BF-B), polyester (PEF) polyacrylonitrile (PAF)) were selected in study. The adhesion parameters obtained by conducting novel fiber-asphalt pullout test, micromorphology area was also observed. mixture determined using indirect tensile cracking test (IDEAL-CT) semi-circular bending (SCB). Basic indicators such as CTIndex flexibility index (FI) used for analyzing. Meanwhile, digital image correlation (DIC) technology adopted quantitatively characterize inhibition mechanism mixtures. results showed that strength BF-A is largest at 25 ℃, followed BF-B, PEF PAF. addition can effectively improve FI mixtures, it found characteristics have a great propagation process. opening velocity curve from DIC analysis development law coefficient determination R2 (stage I change rate timing point 1 time) exceeded 0.85. provide scientific references design application reinforced

Experimental Analysis of Hot-Mix Asphalt (HMA) Mixtures with Reclaimed Asphalt Pavement (RAP) in Railway Sub-Ballast

Materials, Год журнала: 2023, Номер 16(4), С. 1335 - 1335

Environmental safeguards promote innovative construction technologies for sustainable pavements. On these premises, this study investigated four hot mix asphalt (HMA) mixtures-i.e., A, B, C, and D-for the railway sub-ballast layer with 0%, 10%, 20%, 30% reclaimed pavement (RAP) by total aggregate mass a rejuvenator additive, varying bitumen content between 3.5% 5.0%. Both Marshall gyratory compactor design methods have been performed, matching stability, indirect tensile strength, volumetric properties of each mixture. Dynamic stiffness fatigue resistance tests provided mechanical performances. Laboratory results highlighted that RAP additive increase mixtures. In addition, comparative analysis production costs revealed up to 20% savings as increased, life cycle impact (LCIA) proved reduction environmental impacts (up 2% resource use-fossils, 7% climate change, 13% water use). The experimental confirm HMA containing has performances higher than reference mixture only virgin raw materials. These findings could contribute waste management reduce economic costs, since use in is not, so far, Italian specifications construction.
