Pretest warm up procedures for the 3440 nuclear gauge the standard count should be taken daily before any testing is done to check gauge operation and allow the.
Percent density and the moisture content from the nuclear gauge is compared to the optimum moisture limits. Nuclear gauges are also used for industrial mining and scientific purposes. A nuclear gauge also called a nuclear density gauge a soil moisture gauge or a moisture density gauge is a tool used for civil engineering projects and construction that measures soil density or soil water content.
As easy it may seem at first glance it is actually an involved job requiring judgement and experience as well as proper knowledge of compaction techniques equipment and soil types. Pound the pin depress the handle and take the reading. Performing compaction testing using a nuclear density gauge may seem at first to be a simple task.
Nuclear densitometry is a technique used in civil construction and the petroleum industry as well as for mining and archaeology purposes to measure the density and inner structure of the test material the processes uses a nuclear density gauge which consists of a radiation source that emits particles and a sensor that counts the received particles that are either reflected by the test. Of roadway is required extending from the roller pattern area same spreaderbox width at the same designed depth. To prepare a control strip an additional 300 ft.
Nuclear density gauge test section readings are significantly above the target values by more than 8 lb ft3 another control strip will be established.
