IMPROVEMENT OF MECHANICAL PROPERTIES OF RIGID PAVEMENTS

INTRODUCTION
Transportation-basic infrastructure-development

Rigid and flexible

Basic neccesity-stable against loads

Rigid offers more strength “load

But change in temp. “warping up and warping down

To relieve stress-joint

Joint from the weaker plane and most of defects occur there

Increase the mechanical properties such as load carrying capacity and cracking resistance

Methods for improvement

VARI-FORM

ABSTRACT
The need for lighter, stronger, more rigid vehicle structures will increasingly require complex hydroformed structural tubes to increase strength, and decrease weight, cost and part count. This effort will increase the use of high strength, low alloy (HSLA) steel, in place of SAE 1006/1008 or 1010 steel. Traditional hydroforming techniques require the higher elongation of the latter materials. An alternative tube hydroforming process has been d ....etc

ENGINEERING PROPERTIES OF STRUCTURAL
LIGHTWEIGHT CONCRETE



INTRODUCTION

Structural lightweight aggregate concrete is an important and versatile material in modern
construction. It has many and varied applications including multistory building frames and
floors, bridges, offshore oil platforms, and prestressed or precast elements of all types. Many
architects, engineers, and contractors recognize the inherent economies and advantages
offered by this material, as evidenced by the many impressive lightwei ....etc

Abstract :

The case study project is significant since mild steel is used in structure, case hardening, gears, free cutting steels, shafting, forging etc. Mild steel plates were tested for mechanical properties like hardness, tensile strength, yield point etc. Later on the plates were joined by submerged arc welding and the mechanical properties were estimated again. Also weld ability, harden ability, tensile test etc. were conducted for the same result. ....etc

A STUDY ON WEAR AND EROSION PROPERTIES OF RAIL STEEL



Introduction:
Steels represent the most important group of engineering materials as they have the widest diversity of applications of any of the engineering materials. Generally, carbon is the most important element profoundly affecting the mechanical properties of the steels. The term steel is used for many different alloys of iron. These alloys vary both in the way they are made and in the proportions o ....etc

Real estate market place “ Transacting properties online
PR-AP-B114
Background
The objective of the project is to design and develop one stop solution for trading properties online. It bridges the communication between real estate agents, Builders and retail buyers/sellers. The system can be used to store the profiles of agents, builders, buyers, sellers and the properties to be transacted. Buyers are the customers who buy new or resale properties where as sellers are builders (for new properties) or people resel ....etc

ABSTRACT

Corrosion, Stress Corrosion Cracking (SCC) and corrosion fatigue failures of high strength aircraft aluminums are costly and potentially catastrophic material problems affecting the aircraft fleet today. As the service lives of aircraft are extended, the increasing inspection and repair of corrosion in aging aircraft adversely affects fleet readiness, the cost of operation, and personnel safety. Shot peening (SP) is a wid ....etc
