“…Moreover, following the SDGs, an additional improvement was introduced in this academic year. Apart from the standardized design of the pavement structure, some new research about more sustainable materials or construction procedures in pavements was presented, including the reutilization of previous pavements to manufacture some layers in new pavements [48][49][50][51][52][53] or the introduction of waste materials in the production of some materials [54][55][56][57][58][59][60][61][62][63][64]. Hence, students had to choose one of the recently investigated materials or procedures to propose a more sustainable pavement structure.…”

Sustainable Civil Engineering: Incorporating Sustainable Development Goals in Higher Education Curricula

In the current climate emergency context, many national and international organizations have adopted measures to integrate sustainability and Sustainable Development Goals (SDGs) in all their fields of action. Within education, steps have been taken to incorporate the perspective of sustainability at all levels. This process has also started at the university since it plays a fundamental role in the strategy for the implementation of specific policies to promote sustainability. However, sometimes it is difficult to include this type of knowledge in the curriculum, due to the lack of flexibility of the university structure or the lack of time to cover the syllabus. In this scenario, civil engineering plays a main role as a fundamental activity in the creation of services and infrastructures with a high environmental impact. The objective of this study is to show a multidisciplinary approach to working on sustainability in a transversal way in the civil engineering degree and to analyze the impact that this type of initiative can have from the learning point of view. The study shows a curricular trajectory supported by problem-based learning and project-based learning designed to promote sustainability in the practice of civil engineering. The good results obtained in the evaluation of the project and the growing incorporation of the SDGs in the final degree projects suggest that this methodology can be implemented by other university degrees.

To realize the application of epoxy asphalt concrete on roads and solve the problem of the high cost of epoxy asphalt concrete and the causes of bulging in the construction process, a low-content epoxy asphalt mixture was experimentally studied. Rheological and microscopic tests were carried out to study its performance. At the same time, 17 kinds of low-content asphalt mixture Marshall test pieces and rut plate test pieces with different oil stone ratios were made. Their road performances were tested, and a watertight breathable epoxy asphalt mixture was studied to solve the bulging problem. The research shows that, for ordinary roads, a content of epoxy resin of 10–15% can meet both the high-temperature and the low-temperature requirements. For sections with special rutting resistance requirements, a controlled epoxy resin content between 15 and 30% is recommended. When the content of epoxy resin is greater than 30%, epoxy asphalt initially forms a crosslinked spatial network. An epoxy asphalt with a complex structure from asphaltene to epoxy, with ultra-high performance, can be used for small steel bridge pavements. A BBR test showed that, with an increase in epoxy resin content, the low-temperature performance of asphalt gradually weakens. When the content was 20%, epoxy asphalt’s low-temperature performance was weaker than that of SBS-modified asphalt. Under extremely low-temperature conditions, the performance of epoxy asphalt could not meet the specifications. When the voids of low equivalent epoxy asphalt mixture are controlled at 4.1–4.5%, it is watertight and breathable; this can solve the problem of bulging and greatly reduce the cost of projects.

“…In addition, many research works have also been carried out on waterborne epoxy resin (WER)-modified emulsified asphalt, especially in the aspects of fog seal layer and pavement interlayer. The WER can form a porous continuous structure in WE/A with a low content of 3-4% [9][10][11][12][13][14][15][16], which can benefit the high temperature resistance to deformation performance. It has also been shown that WER can effectively improve properties such as thermal stability and adhesion of emulsified asphalt [17][18][19].…”

This study examines the mechanical performance, deformability properties and rheological properties of a newly developed waterborne epoxy resin (WER)-modified emulsified asphalt (WE/A) binder for micro-surfacing. Two types of WER, semi-flexible and rigid, were used to modify the binder. Furthermore, the modification mechanism was investigated using the fluorescent microscope test and the scanning electron microscope (SEM). In addition, the pavement performance at micro-surfacing was studied using the wet wheel wear resistance test, the pendulum friction test and the slurry rutting test. The results indicated that with a small content (<15%) of WER in WE/A, WER existed as a continuous structure (cellular membrane wrapped around asphalt bubbles), thereby enhancing its high temperature properties and mechanical properties. Meanwhile, it also improved the cohesion properties of the transition interface between the aggregate and asphalt (enhanced by at least 30.0%) and the rutting resistance (improved by about 55.3–63.8%). In addition, WER could also improve the peeling resistance and water damage resistance of the micro-surfacing.
