Pavement interface

Abstract

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.

1 . A pavement interface which includes:
 a first section of pavement having a zigzag-shaped trailing edge; and   a second section of pavement having a complemental zigzag-shaped leading edge which abuts the trailing edge of the first section of pavement,   
       such that a boundary between the two sections of pavement is zigzag-shaped. 
     
     
         2 . A pavement interface as claimed in  claim 1 , in which rising or falling edges of the zigzag boundary are inclined by less than 45° relative to the intended direction of traffic flow. 
     
     
         3 . A pavement interface as claimed in  claim 2 , in which the rising or falling edges are inclined by 5° to 20°. 
     
     
         4 . A pavement interface as claimed in  claim 3 , in which each apex or tooth of the boundary is defined by an acute angle of 10° to 40°. 
     
     
         5 . A pavement interface as claimed in any of the preceding claims, in which the boundary is segmented. 
     
     
         6 . A pavement interface as claimed in any of the preceding claims, in which the boundary is from one type of road surface to another. 
     
     
         7 . A pavement interface as claimed in any of  claims 1  to  5  inclusive, in which the interface is as a result of a trench or furrow dug in an existing pavement, and re-surfaced. 
     
     
         8 . A pavement interface as claimed in any of  claims 1  to  5  inclusive, in which the interface is as a result of repair work. 
     
     
         9 . A method of creating a pavement interface, the method including:
 creating, in a first section of pavement, a zigzag-shaped trailing edge; and   creating, in a second section of pavement, a complemental zigzag-shaped leading edge which abuts the trailing edge of the first section of pavement,
 thereby to create a zigzag-shaped boundary between the two sections of pavement.
