The Gravel Road Test Kit is allows materials grading, cohesion (liquid limit and linear shrinkage), compacted strength and aggregate strength of the borrow material to be determined.
The performance of a gravel road is primarily a function of the material selected, as well as testing and control of constructed layer work.
A field test kit to evaluate borrow materials for use as wearing course on unsealed roads and to ensure that the quality of the construction is appropriate, has been developed in conjunction with the International Labour Organisation (ILO).
The thickness probe and RCCD in the kit ensure construction quality assurance. The kit is designed to make use of local water and solar energy (solar oven and calculator) and therefore does not require electricity and running water to be available.
A manual describing the step-by-step test methods with result worksheets and practical guidelines is supplied with every kit.
