Publication number: 20140017005Abstract: Pavement interface (10) and method of creating a pavement interface. The pavement interface (10) includes a first section of pavement (12) having a zigzag-shaped trailing edge (12.1) and a second section of pavement (14) having a complemental zigzag-shaped leading edge (14.2) which abuts the trailing edge (12.1) of the first section of pavement (12). Thus, a boundary between the two sections (12, 14) of pavement is zigzag-shaped.Type: ApplicationFiled: April 2, 2012Publication date: January 16, 2014Inventor: Desmond Hugh Oates
