“…The need for sustainable development is demonstrated by the dramatic climate change and international initiatives regarding the transition to a green economy, the promotion of corporate social responsibility, and the principles of the circular economy [1][2][3][4][5][6][7][8][9][10]. The complexity of the sustainable development phenomenon requires technical and economically viable solutions that ensure a reduced consumption of resources and zero carbon emissions [11][12][13][14][15][16][17][18][19].…”

The cement-based mixture market or dry mix for the ETICS (External Thermal Insulation Composite System) is a highly competitive market and it is becoming increasingly difficult to comply with European sustainability specifications such as the development of products with a lower carbon footprint, lighter and less energy-intensive materials, lower environmental impacts, the option of recycling, etc. This market plays a highly important role in the construction sector, not only for the technical solutions and green innovation it offers but also for the aesthetic aspects. Since 2005, this market has been growing by more than 20% per year, which makes it increasingly attractive with better opportunities. However, this increase has been reduced not only by the crisis of 2007–2008 but also by the pandemic of recent years. The use of cement type CEM II, 42.5R, B-LL, together with a modified RDP ratio, has visibly improved the properties of the thermal insulation system through the adhesion of the EPS boards, the modulus of elasticity, wear resistance, flexibility, and impact resistance. Our research results as green innovation products are above the minimum values agreed by the ETICS standards; in addition, this product has in its formulation a 30% lower carbon footprint compared to any other adhesive in the construction market applied for ETICS systems; therefore, we are talking about a sustainable and clean product, suitable for rehabilitations and ecological constructions adjusted to the European policies of carbon footprint reduction.

Abrasion wear is a significant concern for cutting tools, particularly when milling asphalt concrete due to the presence of hard mineral aggregate particles. The pressure exerted on the cutting tool by the chipped material and the resulting cutting forces directly influence tool wear. To estimate the cutting forces in asphalt milling, the authors propose using either laboratory experiments or cost-effective Discrete Element Method (DEM) modeling—by simulating the real conditions—as direct measurement under real conditions is challenging. This article presents results from an original experimental program aimed at determining the cutting forces during asphalt pavement milling. A specialized stand equipped with a moving plate and recording devices was designed to vary milling depth, rotational speed, and advance speed. The experimental results for horizontal force values were compared with numerical results from DEM modeling. It was found that both increasing the milling depth and the advance speed lead to higher cutting forces. Generally, DEM modeling trends align with experimental results, although DEM values are generally higher. The statistical analysis allowed identification of the milling depth as the most significant parameter influencing cutting force and the optimal combination of milling parameters to achieve minimum horizontal force acting on cutting tooth, namely, 15 mm milling depth and 190 mm/min advanced speed.
