3、 erosion control when exposed to wettingand drying conditions on slabs of rock.This weathering testexposes the rock to wetting and drying cycles similar tofluctuating water levels and weather conditions.The rock slabs,prepared in accordance with procedures in Practice D5121,areintended to be represe
4、ntative of erosion control rock and itsweaknesses.The test is appropriate for breakwater stone,armorstone,riprap and gabion sized rock materials.The limitations of the test are twofold.First,the size of thecut rock slab specimens may eliminate some of the internaldefects present in the rock structur
5、e.The test specimens maynot be representative of the quality of the larger rock samplesused in construction.Careful examination of the rock sourceand proper sampling are essential in minimizing this limitation.Secondly,the test requires the rock slabs to be exposed to 80wetting-drying cycles.The tes
6、t is time intensive and willrequire approximately three months to complete the samplepreparation,testing,and analysis portions of the procedure.1.2 The use of reclaimed concrete and other materials isbeyond the scope of this test method.1.3 UnitsThe values stated in either SI units or inch-pound uni
7、ts presented in brackets are to be regarded sepa-rately as standard.The values stated in each system may not beexact equivalents;therefore,each system shall be used inde-pendently of the other.Combining values from the two systemsmay result in non-conformance with the standard.1.4 All observed and c
8、alculated values shall conform to theguidelines for significant digits and rounding established inPractice D6026,unless superseded by this standard.1.4.1 For purposes of comparing measured or calculatedvalue(s)with specified limits,the measured or calculatedvalue(s)shall be rounded to the nearest de
9、cimal or significantdigits in the specified limits.1.4.2 The procedures used to specify how data are collected/recorded or calculated in this standard are regarded as theindustry standard.In addition,they are representative of thesignificant digits that generally should be retained.The proce-dures u
10、sed do not consider material variation,purpose forobtaining the data,special purpose studies,or any consider-ations for the users objectives;and it is common practice toincrease or reduce significant digits of reported data to becommensurate with these considerations.It is beyond the scopeof this st
11、andard to consider significant digits used in analyticalmethods for engineering design.1.5 This standard does not purport to address all of thesafety concerns,if any,associated with its use.It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and
