Permeable The system can also be designed for water storage

The base and subbase are typically constructed with open-graded aggregates, but can be designed with othermaterials that allow sufficient drainage or storage that can accommodate a design storm (for example, 1 year, 24 hour event).With unit pavers

40、the dry weight of the unit.DISCUSSIONTwo conditions of immersion are designated in standards relating to brick: 24 h in room temperature (60 to 86F (15.5 to 30C) water or 5 h in boilingwater. (Different time intervals are specified for structural tile and other products.) The resulting absorptions a
41、re termed cold water absorption andboiling water absorption.Absorption values are used in brick and tile standards as one factor in classifying these products into durability grades. Absorptions are indicatorsof the extent of firing during manufacture as well as being indicators of durability.absorp
42、tion, initial rate of, na measure of the suction of water upward into a dry brick from a bed face during one minute ofexposure.C1232 15a3DISCUSSIONInitial rate of absorption (IRA) is a distinct property that offers different information from absorption. It is expressed as grams of water picked up in
43、one minute by a net area of 30 in.2 (194 cm2).Initial rate of absorption is one factor influencing the quality of bond between brick and mortar. It is used in brick standards to recommendconstruction practices for enhancing mortar to brick bonding.brick, na solid or hollow masonry unit of clay or sh
