Abstract

An improved roadway and roadway expansion joint is provided, wherein at least some of the adjacent slabs, comprising the roadway, are parallelogram-in-shape and have complementary angles adjacent abutting ends.

Claims

1. A method for prevention of pavement buckling comprising the steps of:

a. constructing a roadway comprising an adjacent series of concrete slabs, each having laterally spaced sides and transverse ends, wherein at least some of said adjacent slabs are parallelogram in shape such that each pair of abutting ends of said adjacent slabs form a joint running obliquely across said roadway.

b. inspecting said roadway for horizontal relative movement between said abutting ends along said oblique joints.

c. constructing at least one additional oblique expansion joint in each area of said roadway where said relative movement is detected before buckling.
