Summary: This research aimed to design and develop asphalt mixes with a partial substitution of natural aggregate by recycled concrete aggregate. Different mixtures were designed using the Marshall methodology with varying percentages of substitution, and their performance was tested to conclude that 70%NA/30%RCA is the best alternative option in terms of performance.

Summary: This paper uses machine learning techniques to help understand specific patterns in Covid patients arising from the transmission-dynamic models of the SARS-CoV-2 virus. The main causes of death in Mexico are found to be related to age, poor eating habits, chronic diseases, and contact with infected individuals lacking proper care. The analysis shows a remarkable accuracy of 87%, which is considered satisfactory.

Summary: This study compared six index properties collected during durability inspections of five Mexican seaports, finding that electrical resistivity is a key durability index for concrete structures in marine environments. Additionally, the study verified the feasibility of using correlations of variables to clean unnecessary data for calculating corrosion initiation time.

Summary: The study focuses on the deposition and analysis of TiO2 and Ag-dispersed TiO2 thin films for efficient water treatment applications. The physical and structural properties of the films were analyzed using various techniques. The presence of Ag nanoparticles on the film surface and throughout the thickness of the Ag: TiO2 thin films was confirmed. The Ag: TiO2 thin films showed a significant improvement in photocatalytic efficiency for the degradation of methylene blue.

Summary: This research aims to improve the durability of earthen constructions by adding an ecological, sustainable material obtained from rice starch extraction. The study focuses on the mechanical and waterproof performance of an earthen mixture with the addition of vegetal origin gel (VOG). The research includes laboratory experiments to develop an easily replicable technology and real interventions in adobe dwellings in Mexico. The material showed good behavior in the early stage.

Summary: This study examines the damage to buildings constructed with ignimbrite blocks bonded with lime mortar in Morelia, Mexico, a UNESCO World Heritage site. The damage is mainly caused by environmental conditions and human activities. The authors analyze the mechanical resistance and microstructural characteristics of the facades and propose potential solutions for the conservation and restoration of damaged monuments.

Summary: The State of Michoacan in Mexico has a diverse architectural heritage that reflects different vernacular typologies and construction techniques. However, this rich cultural knowledge is being lost as many buildings and monuments are being abandoned due to social changes. International cooperation for development and research projects has been carried out to analyze the durability of local materials and traditional constructions, including architectural surveys, laboratory analysis, and interviews with local users.

Summary: This article investigates the characteristics of lime pastes and mortars used in the traditional way and new limes in the market for restoration purposes. Physical and mechanical tests show that traditional slaked lime is more likely to deteriorate than powdered lime. It concludes that powdered hydrated lime has optimal characteristics for restoration activities.

Summary: This paper proposes a methodology for estimating emissions for freight vehicles in Mexico's road transportation corridors. The analysis considers variables such as vehicle fleet conditions, road geometry and quality, environment, and heavy vehicle traffic. The results provide indicators for CO2 emissions per kilometer and emissions per tonne transported. These indicators can be used to establish a baseline for CO2 emissions, implement actions to reduce greenhouse gases, and develop parameter values for cost benefit analysis. They can also be applied to predict emission growth in road transport corridors using geospatial modeling.

Summary: The aim of this investigation was to reduce the consumption of geomaterials in block manufacturing by using construction and demolition waste as a substitute for gravel and tire flakes as a substitute for sand. The results show that the addition of tire flakes decreased the blocks' performance and increased costs, while the incorporation of construction and demolition waste achieved a performance close to that of the control blocks and presented improvements in the modulus of elasticity.
