Los Angeles Abrasion tests in civil engineering play a pivotal role in assessing the durability and wear resistance of materials used in construction, such as aggregates, concrete, asphalt, and road surfaces. These tests simulate real-world conditions to evaluate how materials will withstand abrasion, which is the process of surface wear and erosion …
the asphalt wearing surface should be 4 inches to 5 inches thick, as may be seen from Figure 1, for the service bearing capacity of fine aggregate type materials is about 50 psi. to 65 psi. The use of the coarse aggregate type material in constructing a base course will produce a base capable of withstanding pressures of 75 psi. to above 100
In the realm of construction and civil engineering, a strong foundation is the cornerstone of any successful project. One crucial element that plays a pivotal role in ensuring the durability and stability of structures is the Aggregate Base Course.
