original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A
superscript epsilon (e) indicates an editorial change since the last revision or reapproval.

absorption—the increase in weight of concrete resulting from core—a cylinder of concrete obtained from concrete by means
the penetration of water into the concrete. of a core drill.
absorption test—a test made to determine the absorption of crown—the top or highest point of the internal surface of the
concrete. transverse cross section of a pipe.
admixture—a material other than water, aggregates, cement culvert—a pipeline intended to convey water under a highway,
and fibre reinforcing used as an ingredient of concrete and railroad, canal, or similar facility.
added to the batch immediately before or during its mixture. cylinder (test)—a cast cylindrical specimen of concrete.

box section top slab—upper horizontal portion of a box member.
section in the installed condition. D-load—the supporting strength of a pipe loaded under
box section wall—vertical sides of a box section in the three-edge-bearing test conditions expressed in pounds per
installed condition. linear foot per foot of inside diameter or horizontal span, or
cage—an assembled unit of steel reinforcement consisting of expressed in newtons per linear metre per millimetre of
circumferential and longitudinal bars or wires. inside diameter or horizontal span.
circular reinforcement—a circular-shaped line of reinforce- D-load, 0.01-in. (0.3-mm) crack—the maximum three-edge-

concrete—a homogeneous mixture of portland cement, fine exfiltration—the volume of pipeline flow leaving a sewer and
aggregate, coarse aggregate, and water. The mixture may its connections into the soil from pipe, joints, connections,

both. external load-crushing strength test—a test of the pipe in
which external crushing forces are exerted in specified
directions and locations on a specified length of pipe.
