Add a base course and perhaps a subbase course over the subgrade. A base course offers additional load-bearing capacity. New pavement structural designs often use some sort of granular base course unless subgrade structural support is extremely good and expected loads are extremely low. Base courses are subjected to the same compaction …
Unit weight or density is used to quantify the weight per unit volume of an object. When it is expressed in the basic SI Unit of mass (kg/m 3), it is usually referred to as density, but when expressed in terms of weight (kN/m 3), it is usually referred to as unit weight.. Density (kg/m 3) = Mass (kg)/Volume (m 3). The unit weight of a material is …
