Updating specs: ASTM D4833 replaced by D6241

Neither Mullen Burst Strength ASTM D3786 nor Puncture Strength ASTM D4833 is recognized by ASTM Committee D35 on geosynthetics as an acceptable geotextile test method. Also, AASHTO M288 has recently (M288-05) replaced ASTM D4833 with the Static (CBR) Puncture ASTM D6241.

Starting in 2010, ASTM D4833 and D3786 will no longer be published by GMA members on their QA, QC, or other geotextile technical data. Also, Geosynthetics magazine will highlight the geotextile specs for ASTM D4833 (see chart, top right) and note that they will be replaced by Static (CBR) Puncture ASTM D6241 in subsequent issues (see GMA introduction from December 2009) and in the annual Geosynthetics Specifier’s Guide.

Under the auspices of ASTM, within Committee D35, geosynthetic test methods and specifications are currently being developed, and will continue to be developed, to replace irrelevant textile index test methods. GMA members provide leadership in the development of testing standards for Committee D35.
