Development of asphalt overlay fabric from jute

Abstract

A jute woven fabric employing leno based construction was designed for developing an asphalt overlay fabric, suitable for low traffic roads. To assess the suitability of this product, pavement models embedded with this fabric were subjected to accelerated cyclic mechanical loading and also to extended hygral loading. For the purpose of comparison, similar tests were also conducted on pavement models without any embedded fabric and also on those embedded with commercial fabrics. The experiments reveal that the pavement models embedded with the leno based product perform far better than the others. As a result of further analysis it was found that the grid-like structure of the new construction as also openings of suitable size were primarily responsible for the observed superior behaviour.
