Asphalt is everywhere. It is the curse of urban landscapes along with concrete but it still has some unique features that have been used historically in terrace backyards, factory floors, tennis courts, railway platforms and to graze children's knees in school playgrounds.
In Sydney, some excellent early examples of sheet and block asphalt survive.
Asphalt paving blocks measuring 250 mm. sq. x 125 mm were used in London in the 1830's1 for roads and similar hexagonal blocks have been recovered from East Sydney Technical College. In the 1830's the Champs Elysees was paved with asphalt blocks 300 mm thick.
