Abstract
The static plate load test to control the compaction of soil layers on the road is carried out "in situ" by applying a load on a rigid plate that transmits tension to the ground in two load cycles, to thus being able to measure the deformations produced. All this in order to validate the execution of the compacted soil layers. The model presented for the laboratory allows to simulatewith guarantees the behavior of the soil under the test conditions as it occurs "insitu". Thanks to the laboratory model it is possible to correlate under controlledconditions with another compaction control method such as the dynamic platetest. The dynamic load test is faster to execute, as well as in obtaining results(ODS 9.4), it is also standardized for use in compaction control as long as it hasbeen previously correlated with the static test. The tests carried out to date in thelaboratory on the model allow obtaining a strong correlation between static anddynamic tests with values of "R" greater than 85 %.
