Several technologies established for tire utilization were reviewed in order to determine the best use of discarded tires. The technologies reviewed were retreading, reclaiming, splitting, combustion, pyrolysis, use in breakwaters, erosion control structures, reefs, pavements, general construction materials, etc. Based on the information collected, it was concluded that the use of discarded tir...

In order to reveal the changing law of mechanical response asphalt pavements under action vehicle load and provide references for design durable pavements, three typical pavement structures with flexible base (S1), combined (S2), semi-rigid (S3) were selected perform field strain tests static dynamic using fiber Bragg grating optical sensing technology. The characteristics along horizontal dept...

Evaluating existing flexible pavement condition is a pre-requisite to choose improvement technique that has to be adopted to enhance its quality. To evaluate existing pavements, non-destructive testing methods are desirable. Benkelman Beam and 5th Wheel Bump Integrator are used to conduct non-destructive tests like deflection and roughness surveys on the existing pavement of 4 lane divided carr...

Government agencies and consulting companies in charge of pavement management face the challenge of maintaining pavements in serviceable conditions throughout their life from the functional and structural standpoints. For this, the assessment and prediction of the pavement conditions are crucial. This study proposes a neuro-fuzzy model to predict the performance of flexible pavements using the ...

© Appl. Rheol. 20 (2010) 63293 DOI: 10.3933/ApplRheol-20-63293 Abstract: Bitumen is undoubtedly the most important material in the construction and rehabilitation of flexible road pavements. By increasing the temperature, bitumen changes from brittle solid, to viscoelastic solid and finally to Newtonian fluid. The rheological characteristics of bitumen also vary greatly due to aging, which is a...
