The particle shape of aggregates is determined by the percentages of flaky and elongated particles contained in it. For base course and construction of bituminous and cement concrete types, the presence of flaky and elongated particles are considered undesirable as these cause inherent weakness with possibilities of breaking down under heavy loads. Thus, evaluation of shape of the particles, particularly with reference to flakiness and elongation is necessary.

GEOTEXTILES
Geotextile is defined as a permeable textile material used in contact with soil, rock, earth etc as an integral part of civil engineering project, structure or system
It may be of natural materials such as jute,coir,cotton etc.
Or of synthetic polymers such as polypropylene, polyamide, polyester,polyethylene
INTELLIGENT TRANSPORTATION SYSTEM
INTELLIGENT TRANSPORTATION SYSTEM
Why it’s Needed?
Traffic congestion-insufficient road development-growing number of vehicles.
Low speed, increased accident rates, increased fuel consumption, and increased pollution.
Impossible to build enough new roads or to meet the demand.
These explore the concepts that treat highway systems and the vehicles that use them as integrated system. Among them is the concept [...]
Ground Freezing – Tunneling Methods
Ground Freezing
• Ground freezing is a process of making water-bearing strata temporarily impermeable and to increase their compressive and shear strength by transforming joint water into ice.
• Freezing is normally used to provide structural underpinning; temporary supports for an excavation [...]
Kansai Airport
Kansai International Airport is an international airport located on an artificial island in the middle of Osaka Bay, off the shore of the cities of Sennan and Izumisano and the town of Tajiri in Osaka Prefecture, Japan. (It should not be confused with Osaka International Airport, which is closer to the city and now handles [...]
