Rigid pavements distribute wheel loads by

the beam action of the Portland cement concrete (PCC) slab, 

The purpose of the …………… are to:

o

……………is

the ratio of the load-bearing capacity of the soil to the load-bearing capacity

of a high-quality aggregate, multiplied by 100. 

In …………………, the base layer is optional,

depending on the engineering properties of the subgrade. 

The

design procedure for rigid pavements is based on a selected reduction in

serviceability and is similar to the design procedure followed for flexible

pavements. However, instead of measuring pavement strength by using a

structural number, the thickness of the PCC slab is the measure of strength. 

……………………estimates the probability that the

pavement will perform at or above the TSI level during the design period.

…………………………is a factor that is used to

account for the ability of pavement to transfer a load from one PCC slab to

another across the slab joints.

The primary function of the pavement

structure is to distribute the surface stresses (contact tire pressure) to an

acceptable magnitude at the subgrade (to a magnitude that prevents permanent

deformation).

…………………………..is a measure of the tensile

strength of the concrete and is determined by loading a beam specimen, at the

third points, to failure.

……………………takes into account the designers'

inability to accurately estimate the variation in future W
