Textiles were first applied to roadways in the days of the Pharaohs Even they struggled with unstable soils which rutted or washed away They found that natural fibers, fabrics or vegeta-tion improved road quality when mixed with soils, particularly unstable soils Only recently, however, have textiles been used and evaluated for modern road construction This fact sheet clarifies the confusion over terms and definitions of geo textiles, and discusses their common roadway and erosion control applications

USE OF DISCRETE FIBER IN ROAD CONSTRUCTION

PRESENTED BY: SACHIN KAPOOR



ABSTRACT



New materials and construction techniques are required to provide Civil Engineering with alternatives to traditional road construction practices. Traditional techniques have not been able to bear the mixed traffic load for a long time. Therefore the pavement requires overlaying. To overcome this problem fiber inclusion in pavements is adopted nowadays. This paper highlights on the use of discrete fiber in road ....etc

UTILISATION OF WASTE PLASTIC IN BITUMINOUS MIXES FOR ROAD CONSTRUCTION

INTRODUCTION
Bitumen is a useful binder for road construction. Different grades of bitumen like 30/40, 60/70 and 80/ 100 are available on the basis of their penetration values. The steady increase in high traffic intensity in terms of commercial vehicles, and the significant variation in daily and seasonal temperature demand improved road characteristics. Any improvement in the property of the binder is the needed.
Today the availability of the ....etc
