The different grades of road base materials (G1 to G10) relate to specific proportions of parent and non-parent rock as given in the COLTO specification, and are produced by layering different stone and sand materials on large stockpiles, and then cutting down through the layers to achieve the required pre-compaction gradings. See Figure 7
Assessment procedures and requirements for road segment information data are specified. Different distress types are classified and detailed descriptions of degree of distress (including photographic plates illustrating condition) for each of the distress types are given. TMH 9 is a companion document to TMH 22 on Road Asset Management
Granite is a very hard, granular, crystalline igneous rock which consists mainly of quartz, mica, and feldspar and is often used as building stone. Sandstone is defined as a rock which is composed of sand-sized grains of various minerals mostly of uniform size and often are smooth and rounded
