Flexible Pavement. Rigid Pavement. 1. It consists of a series of layers with the highest quality materials at or near the surface of pavement. It consists of one layer Portland cement concrete slab or relatively high flexural strength. 2. It reflects the deformations of subgrade and subsequent layers on the surface.

The type of flexible pavement that consists of a directly placed bituminous layer over the sub-grade layer is known as full-depth asphalt pavement. Such a type of flexible pavement can withstand the considerable intensity of stresses and is usually preferred in areas where local construction materials are not available.

The design of fractured slab techniques begins with the design of a new flexible pavement as described in Section 400. The structural number required for the new flexible pavement is the basis for all the fractured slab designs. Because these techniques turn a rigid pavement into a flexible pavement, subgrade conditions take on increased ...

The stresses that occur in a flexible pavement under load are quite complex. Although rigid pavement stresses have been routinely calculated since the 1920s, routine calculation of flexible pavement stresses is a more recent development. First, two-dimensional layered elastic programs offered desktop computers the ability to calculate these ...

CHAPTERS 600 – 670 PAVEMENT ... Flexible Pavements. These are pavements in which the surface course is an asphalt bound structural layer underlain with a non-rigid base. This type of pavements is engineered to bend or flex when loaded. Flexible pavements transmit and distribute

401.1 Design 401.1.1 Plant Mix Bituminous Base (PMBB) Course. Use of PMBB courses should be limited to bituminous bases beneath Plant Mix Bituminous Pavement (PMBP) surface mixtures on full depth light duty pavements, as base widening on routes designated as light duty corridors, or on any bypasses or temporary roadways, regardless of the corridor designation.

2.2 Types of Flexible Pavements. These pavements may fall into one of the following categories: thin hot-mix asphalt on an asphaltic bound base (semi-rigid). Stabilization of the subgrade layer can be used with any of the above pavement types. Typical stabilizers include asphalt cement (for base only), lime, cement, fly ash, or lime-fly ash ...

Flexible pavements can be defined as one consisting of a mixture of asphaltic or bituminous materials and aggregate placed on a bed of compacted granular material of appropriate quality in layers over the subgrade.. Water-bound macadam (WBM) roads and stabilized soil roads with or without bituminous toppings are examples of flexible or bituminous pavements.

Flexible (left) and Rigid (right) Pavement Load Distribution. Overall, it may be somewhat confusing as to why one pavement is used versus another. Basically, state highway agencies generally select pavement type either by policy, economics or both. Flexible pavements generally require some sort of maintenance or rehabilitation every 10 to 15 years.

Typical flexible pavement structure consisting of surface course and the underlying base, sub-base and sub-grade courses. Each of these layers contributes to structural support and drainage. The surface course (typically an HMA layer) is the stiffest and contributes the most to pavement strength.

Flexible pavements are those pavements which reflect the deformation of subgrade and the subsequent layers to the surface. Flexible, usually asphalt, is laid with no reinforcement or with a specialized fabric reinforcement that permits limited flow or re positioning of the roadbed under ground changes. The design of flexible pavement is based on load

A pavement interlayer may be placed between layers of new flexible pavement, such as on an asphalt leveling course, or on the surface of an existing flexible pavement. A GPI should not be placed directly on coarse surfaces such as a chip seal, OGFC, areas of numerous rough patches, or on a pavement that has been cold planed.

Flexible pavement is composed of a bituminous material surface course and underlying base and subbase courses. The bituminous material is more often asphalt whose viscous nature allows significant plastic deformation. Most asphalt surfaces are built on a gravel base, although some 'full depth' asphalt surfaces are built directly on the subgrade.
