ASTM C136

ASTM C136 is a standard test method used to determine the particle size distribution of aggregates, such as sand and gravel, in construction materials. The process involves passing aggregate samples through a series of sieves with different mesh sizes to classify the sizes of the particles. This measurement is crucial for ensuring the right mixture in concrete and asphalt, affecting their strength and durability. By following ASTM C136, engineers and builders can ensure the quality and consistency of materials used in various construction projects.
