Segmental pavers have been used for thousands of years. The Romans built roads with them that are still there. But it was not until the mid-1940s that pavers began to be produced out of concrete. It started in the Netherlands where all the roads are made to be flexible because the country is below sea level and the ground shifts, moves and sinks. Poured concrete is not an option because it will crack. Individual units not set in concrete, and placed in sand perform far better than concrete. Before the paver was made from concrete either r ....etc

literature review in flexible pavement design ppt

There are two types of pavements based on design considerations i.e. flexible pavement and rigid pavement. Difference between flexible and rigid pavements is based on the manner in which the loads are distributed to the subgrade.

Before we differentiate between flexible pavements and rigid pavements, it is better to first know about them. Details of these two are presented below:

Flexible Pavements:

Flexible pavement can be defined as the one consisting of a mixture of asphaltic or bituminou ....etc

seismic analysis of interlocking blocks in walls pdf

ABSTRACT :

This paper proposes new masonry infill walls using ductile interlocking blocks, and describes their availability for retrofitting existing structures. Although no reinforcement is provided in the proposed infills, they can resist out-of-plane loads by the interlocking mechanism between blocks. Three reinforced concrete frames were prepared, and two of them were retrofitted by installing the proposed infills, which were constructed in different bond patterns. Quasi-static loading ....etc

Abstract
The aim of this paper is to contribute to the improvement of the methodologies used in structural pavement evaluation, concerning in particular the backcalculation of layer moduli based on Falling Weight Deflectometer (FWD) together with Ground Penetrating Radar (GPR) test results and using Artificial Neural Network (ANN) technique for the analysis. A brief description of the test procedures and analysis methods is made. The bearing capacity of a pavement is generally evaluated through non-destructive load testing (NDT). Based on the ....etc

Black cotton soils are soils that expand when it becomes wet it
gets expand and when it becomes dry it gets shrink . This
continuous expansion and contraction will decreases its
strength.,. Foundation with swelling soil will heave and can
cause lifting of a building or structure laid on it whenever
the moisture content rises.
expansive soil consists of mineral like smectite, bentonite,
montmorillonite, beidellite, vermiculite, attapulgite,
nontronite, illite and chlorite. There are some amount of
sulfate salts which will expand due to ....etc
