Abstract

Asphalt pavements are susceptible to damage in low-temperature environments, and incorporation phase change materials (PCMs) can effectively address this issue. This study developed a novel low-temperature phase change material (LPCM) with a phase change enthalpy of 60.3 J/g through a simple physical combination of fly ash cenospheres, tetradecane, and water glass. It exhibited excellent cost-effectiveness, chemical compatibility, and good thermal stability, meeting the construction conditions for asphalt pavement engineering. The low-temperature crack resistance of LPCM-modified asphalt mixtures has been enhanced by 22.1 %, while both high-temperature stability and moisture stability are ensured. The incorporation of LPCM resulted in a decrease in thermal conductivity and improved insulation properties of the asphalt mixture. The specimen incorporating the highest dosage of LPCM demonstrated an enhanced temperature buffering capacity, with a temperature variation of 1.22 °C compared to the control specimen, indicating the effectiveness of LPCM in low-temperature regulation.

期刊介绍： Thermal Science and Engineering Progress (TSEP) publishes original, high-quality research articles that span activities ranging from fundamental scientific research and discussion of the more controversial thermodynamic theories, to developments in thermal engineering that are in many instances examples of the way scientists and engineers are addressing the challenges facing a growing population – smart cities and global warming – maximising thermodynamic efficiencies and minimising all heat losses. It is intended that these will be of current relevance and interest to industry, academia and other practitioners. It is evident that many specialised journals in thermal and, to some extent, in fluid disciplines tend to focus on topics that can be classified as fundamental in nature, or are ‘applied’ and near-market. Thermal Science and Engineering Progress will bridge the gap between these two areas, allowing authors to make an easy choice, should they or a journal editor feel that their papers are ‘out of scope’ when considering other journals. The range of topics covered by Thermal Science and Engineering Progress addresses the rapid rate of development being made in thermal transfer processes as they affect traditional fields, and important growth in the topical research areas of aerospace, thermal biological and medical systems, electronics and nano-technologies, renewable energy systems, food production (including agriculture), and the need to minimise man-made thermal impacts on climate change. Review articles on appropriate topics for TSEP are encouraged, although until TSEP is fully established, these will be limited in number. Before submitting such articles, please contact one of the Editors, or a member of the Editorial Advisory Board with an outline of your proposal and your expertise in the area of your review.
