ASTM D1196/D1196M-21 PDF Download

ASTM D1196/D1196M-21 describes a standardized procedure for conducting nonrepetitive static plate load tests. These tests are performed on subgrade soils and compacted pavement components, in either their natural state or compacted condition. The purpose of these tests is to provide data that can be used to evaluate and design rigid and flexible-type airport and highway pavements.

The standard specifies the apparatus and procedure that should be followed to conduct these tests accurately and consistently. The test involves applying a static load on a plate placed on the soil or pavement component being tested. The load is applied incrementally, and the resulting vertical and horizontal deformations are measured. These measurements are then used to calculate the plate load deformation modulus.

The information obtained from these tests is essential in the evaluation and design process of airport and highway pavements. It helps in understanding the load-bearing capacity, deformation characteristics, and overall performance of the soils and pavement components. This data is crucial in determining design parameters, such as pavement thickness and reinforcement requirements, and ensuring the structural integrity and durability of the pavements in airport and highway applications.
