GEOSYNTHETICS IN PAVEMENT DESIGN
INTRODUCTION
 Pavements are civil engineering structures used for the purpose of operating wheeled vehicles safely and economically.
 The development of geosynthetics in the past three decades has provided the strategies for enhancing the overall performance of the paved roadways.
 Commonly a paved road becomes a candidate for maintenance when its surface shows significant cracks and pot holes.
GEOSYNTHETICS
 Geosynthetics is defined as “a planar product m ....etc

The growing traffic volume on roads and increasing demand for stronger, more durable and safer pavements have led to the search for new materials, design procedures and more cost efficient solutions. As a result, more innovations in design procedures and construction technique are taking place. An extensive network of highways and airfields constructed with long lasting pavements is essential to the growth of an economy, which depends largely on efficient transportation for commercial, business and personal uses Flexible pavements are most comm ....etc

Continuosly Reinforced Concrete Pavement as the title suggests this type of pavement is reinforced throughout in longitudinal direction. This type of pavement has no transverse joints unless and until there is end of pavement or the pavement comes in contact with some other pavement or bridge. A longitudinal joint exists only if the road is wider than 14 feet. Due to reduction of joints smooth and continuous riding is possible resulting in fuel saving. Also CRCP roads are maintenance free if properly constructed and care is taken while placemen ....etc

Fiber Reinforced Concrete
“FRC is defined as a composite material consisting of concrete reinforced with discrete randomly but uniformly dispersed short length fibers.”
Fibers are generally discontinuous, randomly distributed through out the cement matrices.
Enhances flexural and tensile strength of the concrete.
Fibers may generally be classified into two: organic and inorganic.
Contd. ….
Volume fraction – measure of fiber in concrete.
Typically ranges from 0.1 to 3%.
Aspect ratio - fiber length (l) ....etc
