Design of Flexible Airport Pavements

Design of Flexible Airport Pavements

Introduction The structure of an airport flexible pavement may consist of untreated or treated (stabilized) granular base overlain by an impervious or waterproofing riding course much in the same way as with flexible highway pavements. However, it is recommended that whenever possible, flexible airport pavements must be constructed as full-depth asphalt pavements as such a …

Pavement failures [All the Essential things you should know]

Pavement failures Pavements begin to deteriorate when opened to traffic after construction as a result of the cumulative effect of traffic loading and environmental factors.  The figure below provides a pictorial representation of the state of a pavement defined by its present serviceability index (PSI) at any given time. The present serviceability index  (PSI) is …

Interlocking Concrete Block Pavements: Design, Construction and stability

Concrete Block pavements

Introduction Historically, interlocking concrete block paving technique originated from small-element surfacing which involved stone setts, wooden blocks, and bricks used for early city pavements in some parts of Europe in the nineteenth and twentieth centuries. Today, interlocking concrete block pavement is extensive and covers the following: Paving of container terminals at ports and harbors Paving …

Stresses In Rigid Pavements (The Essentials you should know)

STRESSES IN RIGID PAVEMENT

Introduction A Rigid pavement is a pavement consisting of a relatively thin slab of Portland cement concrete overlying a sub-grade or base-course or a regulating layer. Unlike flexible pavements, rigid pavements are not considered as a multi-layer structure because the high stiffness of the slab helps the slab to distribute load over a relatively wide …
