The results of the deformation and cohesion tests can be used for specification purposes or for mix design purposes, or both. For example, these values can be used for specification compliance testing of aggregate properties. They can also be used for specification compliance testing of the mix. The cohesion test is sometimes used for fine mixes such as sand mixes wherein cohesion, or tensile strength, is of major or primary importance. The cohesion test is also sometimes used for the design of cold mixes containing emulsified asphalt.

1. Scope

1.1 These test methods cover the determination of (1) the resistance to deformation of compacted bituminous mixtures by measuring the lateral pressure developed when applying a vertical load by means of the Hveem stabilometer and (2) the cohesion of compacted bituminous mixtures by measuring the force required to break or bend the sample as a cantilever beam by means of the Hveem cohesiometer.

1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.

1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
