Pavement Thickness Design

Some factors which influence the total pavement thickness are the subgrade strength, quality of construction materials and the design traffic. We have experience in NSW and QLD carrying out flexible and rigid pavement thickness designs for residential, Council and State-controlled roads using design charts and mechanistic pavement design software such as Circly. We can also assist in flexible pavement resurfacing and rehabilitation projects.

Subgrade Improvement

Where the subgrade strength is so low that a proof roll will fail and/or the depth of removal and replacement will is cost prohibitive, we can assist by providing subgrade treatments which will provide the necessary support at the top of subgrade in order to minimise the total pavement thickness. These treatments may include cement and/or lime modification or geosynthetics.
