1.2 Cast stone units covered under this specification include both wet cast and vibratory dry tamp products. Production methods of cast stone can vary among manufacturers; many production methods are acceptable provided the delivered cast stone meets the requirements of this specification.
1.3 Surface textures, finish, color, special applications, or other features shall be specified by the purchaser. Slump, manufacturing method, and apparatus shall be selected by the manufacturer and not specified by the purchaser.
1.4 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

ABSTRACT
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.
