It is standardized as ASTM D93, EN ISO 2719 and IP 34 [1] The United States Environmental Protection Agency (EPA) has also published Method 1010A: Test Methods for Flash Point by Pensky-Martens Closed Cup Tester, part of Test Methods for Evaluating Solid Waste, Physical/Chemical Methods, which references the ASTM standard series
The original Proctor test, ASTM D698 / AASHTO T99, uses a 4-inch-diameter (100 mm) by 4.584-inch-high (116.4 mm) mold which holds 1/30 cubic feet of soil, and calls for compaction of three separate lifts of soil using 25 blows by a 5.5 lb hammer falling 12 inches, for a compactive effort of 12,375 ft-lbf/ft 3.
The cone penetration or cone penetrometer test (CPT) is a method used to determine the geotechnical engineering properties of soils and delineating soil stratigraphy. It was initially developed in the 1950s at the Dutch Laboratory for Soil Mechanics in Delft to investigate soft soils.
ASTM International, formerly known as American Society for Testing and Materials, is a standards organization that develops and publishes voluntary consensus technical international standards for a wide range of materials, products, systems and services. Some 12,575 apply globally.
Dynatest was the first company to develop the Light Weight Deflectometer (LWD) The Light Weight Deflectometer is a portable falling weight deflectometer used primarily to test in situ base and subgrade moduli during construction. LWD measurement is faster than the isotope measuring method [clarification needed] and requires no reference ...
The procedure is standardized by ASTM D4945-00 Standard Test Method for High Strain Dynamic Testing of Piles. It may be performed on all piles, regardless of their installation method. In addition to bearing capacity, Dynamic Load Testing gives information on resistance distribution (shaft resistance and end bearing) and evaluates the shape and ...
The manual graduated wedge method is retained for use on shorter sections of road or where the rolling straight-edge proves impractical to use. [6] The specification sets out the number of deviations greater than 4 millimetres (0.16 in) and greater than 7 millimetres (0.28 in) that are permitted per 300 metres (980 ft) section of carriageway.
