The Gravel Road Test Kits (GRTKs) were developed as a result of a joint effort between the CSIR and the International Labour Organisation, in which the team developed the field test kit to evaluate borrow pit materials for use as wearing course on unsealed roads and to ensure that the quality of the construction is appropriate. Borrow pits are areas close to major construction projects where soil, gravel, and sand are dug up for use in the construction.
