... analysis and full scale testing took place. The phenomenal increase in the weight of militar y and civilian aircraft has led to a more analytical approach to the design of structural pavement layers, with less reliance on empirical solutions, in order to achieve economic designs. With the advent of modern...

... tests were carried out in the Transport Research Laborator y s Pavement Test Facility at Crowthorne, Berkshire. Test roads consisted of a single layer of granular material placed on a Gault clay subgrade. The roads had base thicknesses of 200, 350 and 560 mm. Wheel loads of 44 and 80 kN were used...

... in the calculations. 42. The deflection from the test load measured at the road surface is the sum of the deflection increments in each layer of road pavement or underlying soil beneath the test load, or the sum of the product of strain from the test load and layer thickness. Because weaker layers deflect more...

... pavements has been to specify a structure comprising a number of layers of uniform thickness. Considerable care is taken to specify the material and thickness of each layer with the objective of achieving a minimum whole life cost for the structure. In the case of dual carriageway roads, the design...
