Abstract | On the basis of the Canadian Department of Transport's load test data, a method for calculating the surface deflection of an existing flexible pavement under a loaded rigid bearing plate is described. When all other factors are equal, the surface deflection depends upon (a) the thickness of flexible pavement, and (b) the subgrade strength. For any specified traffic volume (less than unlimited) of a given design wheel load and tire inflation pressure, the permissible surface deflection when measured by means of a rigid bearing plate carrying the same total load and unit pressure, must be varied with the strength of the underlying subgrade. This implies that for flexible pavements not strong enough to carry unlimited traffic, a given Benkelman beam deflection under a specified wheel load does not indicate the same ability to carry traffic, if the strengths of the underlying subgrades are different. |
