The sheets specify pavement structure layers including asphaltic wearing course, asphaltic base course, base course, sub-base and subgrade, with variants such as flush or raised kerbs and pavement transitions between flexible and rigid pavement. Details include reinforcement and connection notes for rigid pavement, geotextile membrane placement, jointing and sealing provisions, typical section diagrams with scale references, and sieve
