Anotácia textu normy ASTM C825-24 :
This specification covers precast concrete barriers intended for use adjacent to a roadway or as a median to redirect vehicles unintentionally leaving the roadway. The acceptance criteria for these barriers shall be based on strength properties, dimensional properties, and end results. Conformance as to materials (cement, aggregates, admixtures, and steel reinforcements), design (concrete strength, air entrainment, dimensions, steel reinforcements, concrete finish, lifting devices, anchorage, and reinforcement laps, welds, and splicing), and manufacture (mixture, accelerated curing, water curing, membrane curing, and forms) should be observed precisely. Physical requirements shall be examined by compression, curing compression, and core compression tests.
