This course provides criteria for the design of rigid pavements for roads, streets, walks, and open storage areas at U . S . Army mobilization installations for the loadings and conditions set forth herein.
Basis of pavement design: The prime factor influencing the structural design of a pavement is the load-carrying capacity required . For rigid pavements, the slab thickness necessary to provide the desired load-carrying capacity is a function of five principal variables :
(a) vehicle wheel load or axle load,
(b) configuration of the vehicle wheels or tracks,
(c) volume of traffic during the design life of the pavement,
(d) modulus of rupture (flexural strength) of the concrete, and
(e) modulus of subgrade reaction.
