A manual describing the step-by-step test methods with result worksheets and practical guidelines is supplied with every kit.

Benefits and Function:

The performance of a gravel road is primarily a function of the material selected, as well as testing and control of constructed layer work.

The field test kit enables the practitioner to evaluate materials for use as wearing course on unsealed roads and to ensure that the quality of the construction is appropriate.

The function and objective of the travel gravel roads field kit is to enable the practitioner to perform certain basic tests on materials in the field, without the back up of a soils laboratory.

The kit has been developed specifically for evaluating gravel roads and therefore does not contain the required tests to evaluate bituminous surfaces.
Layerwork underneath bituminous surfaces can be evaluated to an extent.
