rigid pavement

Recognize the most significant factors for consideration in the design of flexible and rigid pavements.

Full set of steel pads for a rigid pavement aerodrome.

A guide to the structural design of flexibly and rigid pavements for new roads.

Rigid pavements must be designed to endure frequently repeated traffic loadings.

Design flexible and rigid pavements using different design methods.

Finally, design procedures for rigid pavements are explored.

In rigid pavements the upper layer is a portland cement concrete slab.

Key words: rigid pavement, finite element model, stress, deflection, design, evaluation.

Some rigid pavements incorporate a bituminous overlay that can be replaced when worn out.

Combination of flexible and rigid pavements made of bitumen.

Defects differ between flexible and rigid pavements.

Key words: rigid pavements, elastic solid, edge loading, numerical solutions, slabs.

Rigid pavements are generally used in constructing airports and major highways, such as those in the interstate highway system.

Pavement materials and tests; design of flexible and rigid pavements; pavement management.

One major design consideration of rigid pavements is reducing fatigue failure due to the repeated stresses of traffic.

The required overlay thickness for a structurally sound rigid pavement is much smaller than for one that has reached the end of its service life.

The typical designed service life of a rigid pavement is between 30 and 40 years, lasting about twice as long as a flexible pavement.

The rigid pavements have four subgrade categories:

Key words: sealant, rigid pavement, concrete, chloride intrusion, corrosion, dowels.

Heights of cover are to the top of rigid pavements or the bottom of flexible pavements.

Rigid pavements are generally constructed in three layers - a prepared subgrade, base or subbase, and a concrete slab.

Concrete pavement is a rigid pavement structure, which distributes heavy axle loads over a large area by beam action.

Portland cement concrete surface courses are referred to as rigid pavements, or concrete pavements.

Near the end of a rigid pavement's service life, a decision must be made to either fully reconstruct the worn pavement, or construct an overlay layer.

Due to the relatively low tensile strength of concrete, thermal stresses are extremely important to the design considerations of rigid pavements.
