A NEW METHOD OF CALCULATING THE THICKNESS OF FLEXIBLE PAVEMENTS BY MEANS OF THE CBR INDEX

UN NUOVO METODO DI CALCOLO DEGLI SPESSORI DELLE PAVIMENTAZIONI FLESSIBILI A MEZZO DELL'INDICI CBR

This article shows that in conjunction with the CBR index, it is possible to calculate the thickness of flexible pavements by a method based on the friction and cohesive characteristics of the materials used. The concept is based on the hypothesis that each pavement layer is subjected by traffic to a series of punching actions which progress in similar fashion to that proved during CBR tests, and that this action takes place without fracture of the pavement materials. This contrasts with the relative strengths of the materials and the bearing capacity of the supporting layer or of the subgrade. In the calculations and examples presented it is supposed that the distribution of the load on the layer considered and the one below it is uniform, and that the distribution of compression stresses inside the layers (a function of strength) is also uniform. /TRRL/
