Special Issue Information

Dear Colleagues,

Currently, achieving carbon neutrality is a common goal worldwide. Transportation infrastructure is characterized by high resource demand and energy consumption. Road infrastructure requires a large amount of non-renewable resources during the construction phase, and asphalt and cement pavements, as the most important components of road transportation infrastructure, generate high levels of carbon emissions during their construction and maintenance phases. Therefore, reducing the dependence of road infrastructure on non-renewable resources, upgrading the level of construction and maintenance, increasing the level of recycling of infrastructure materials, and developing low-carbon materials or related technologies are very important for the sustainable development of transportation and the goal of carbon neutrality. Based on the principle of conserving non-renewable resources and energy, some attempts have been made to construct low-carbon emission transportation infrastructure, such as using typical solid waste to replace natural resources in concrete, developing warm-mix asphalt and cold-mix asphalt technologies for asphalt pavements, and improving the recycling efficiency of infrastructure by optimizing processes and equipment. To help achieve the goal of carbon neutrality in transportation infrastructure, this topic aims to attract articles on new materials or innovative technologies for carbon neutral transportation infrastructure. We welcome original research or review articles with a clear application focus in these areas.

In order to accurately assess the fatigue performance of semi-rigid base layers, this paper proposes a novel fatigue testing method for semi-rigid base layers that takes into account the spatial stress state. Based on this method, the fatigue performance of three types of reinforced semi-rigid base-layer materials (steel wire mesh, plastic geogrid, and fiberglass) was tested and compared with unreinforced materials. The fatigue strain evolution patterns of these materials were analyzed, and a fatigue strain characteristic value at the limit state was proposed as an evaluation index for the fatigue failure of base layer materials. The results showed that in terms of fatigue performance, plastic geogrid > steel wire mesh > fiberglass > unreinforced specimens. The development of tensile strain can be approximately classified into a three-stage growth pattern, consisting of “curve + straight line + curve”. For the unreinforced specimens, the three stages of bending strain accounted for 10%, 70%, and 20% of the total fatigue life, respectively. The fatigue failure stages of the three types of reinforced materials had similar proportional ranges, representing 5%, 75%, and 20% of the total fatigue life, respectively. The fatigue strain characteristic values for plastic geogrid, steel wire mesh, fiberglass, and unreinforced specimens were 371 με, 280 με, 280 με, and 195 με, respectively. In summary, the use of reinforced materials within semi-rigid base layers enhances their fatigue performance, providing new insights and methods for extending the service life of road surfaces and offering scientific guidance for the practical application of reinforced materials in semi-rigid base layer road surfaces’ fatigue performance.

The concentration of atmospheric greenhouse gases is being amplified by human activity. Building energy consumption, particularly for heating and cooling purposes, constitutes a significant proportion of overall energy demand. This research aims to establish a smart evaluation model to understand the thermal requirements of building occupants based on an open-access dataset. This model is beneficial for making reasonable adjustments to building thermal management, based on factors such as different regions and building user characteristics. Employing Bayesian-optimized LightGBM and SHAP (SHapley Additive exPlanations) methods, an explainable machine learning model was developed to evaluate the thermal comfort design of buildings in different areas and with different purpose. Our developed LightGBM model exhibited superior evaluation performance on the test set, outperforming other machine learning models, such as XGBoost and SVR (Support Vector Regression). The SHAP method further helps us to understand the interior evaluation mechanism of the model and the interactive effect among input features. An accurate thermal comfort design for buildings based on the evaluation model can benefit the carbon-neutral strategy. Full article
