24p.: Illus.; 21 x 28 cm Sampling and testing aggregates ensures they meet specifications for construction projects, involving collecting representative samples (from stockpiles, belts, trucks) following standards like ASTM D75 or AASHTO T2, then reducing them in the lab for tests like sieve analysis (particle size), specific gravity, water absorption, and soundness to determine suitability for concrete, asphalt, or base materials. Proper sampling minimizes errors, while testing verifies quality, strength, durability, and particle distribution for safety and performance, preventing structural issues.
