Scope and Objectives

The broad objective of this project is to evaluate the present condition of existing road and pavement structure to determine the likely causes for development of slippage and cracking expressway and to recommend needed remedial measures.

The scope of work includes the following:

Benkelman Beam Deflection measurements on selected / representative road sections covering all possible conditions
Traffic volume surveys for 24 hours, round the clock, in both carriageways, at one location
Axle loads surveys for 24 hours, round the clock, at one location
Test pits observations and collection of subgrade and other road construction materials and mixes retrieved from the pits
Roughness measurements using calibrated Fifth Wheel Bump Integrator
Laboratory investigations of materials and mixes used for road construction
Analysis of data to determine the likely causes of distress
Recommend suitable remedial measures
 
Methodology
The field and laboratory evaluations / investigations, as per the scope of work, were undertaken to evaluate the structural and functional conditions of the pavement; collect data on present day traffic volume and their composition; axle loading and other relevant informations. Cores of bituminous mixes were also taken for determining the quality of materials and mixes. Construction standards achieved with regard to density, binder content and mix gradation etc. were also examined.
Field work has been completed and laboratory investigations of materials / mixes is currently in progress.
 
Significance / Utilization Potential
The study will identify likely causes resistence for development of distress viz, slippage and cracking. Based on the results obtained through field and laboratory evaluation, the remedial measures will be recommended for ensuring effective functioning of the Expressway.
