The Proctor compaction test is a laboratory method of experimentally determining the optimal moisture content at which a given soil type will become most dense and achieve its maximum dry density.The test is named in honor of Ralph Roscoe Proctor [], who in 1933 showed that the dry density of a soil for a given compactive effort depends on the amount of water the soil …


The loose drop weight of a relatively uniform (all the rocks are similar size and shape) 3/4" stone will be about 80-90% depending on the stone (angularity and phi).

May 05, 2011· If the 3/4" crushed stone has sufficient fines in it, a proctor curve can be obtained. We see it used extensively on projects. Ron is correct that nuclear density testing on clean rock is inaccurate at best. The choice between backscatter and direct transmission can be governed by the layer thickness.


the ASTM Method D 2049 (Relative Density), the Washington Spring-Loaded Vibratory Compactor Method, the Marshall Hammer Test, and the Gyratory Compactor Procedure. The aggregates tested were a granite-gneiss, a crushed gravel, a dolomitic limestone, and a basalt. A prototype field compaction 'testing program was conducted using the same


Engineering properties of the two crushed stones are shown.in Table 1. The Bedford stone contains more gravel, less sand and more clay size particles, and has a measurable plasticity. The optimum moisture content for compaction is higher and the compacted density lower than for the Garner sample.

Using a given energy, the density of soil varies as a function of moisture content. This relationship is known as the moisture-density curve, or the compaction curve. The energy inputs to the soil have been standardized and are generally defined by Standard Proctor (ASTM D 698 and AASHTO T 99) and Modified Proctor (ASTM D 1557 and
