Abstract

This paper evaluates the moderation effect of raveling on bleeding failure of Flexible pavements with the support of moderation models. Failures in flexible pavements results due to its component layers which undergo distress due to innumerable causes. There are different types of failures in flexible pavements like alligator cracking, corrugations, shoving, pot holes, rutting, raveling and bleeding. Determination of the type and extent of failure and its reason is necessary to facilitate correction in mix design, construction and maintenance for the road projects. A moderator is a qualitative or quantitative variable that affects the direction and/or strength of the relation between an independent or predictor variable and a dependent or criterion variable. Four road sections have been considered for data collection and model validation. Linear models have been developed to check the mediation and moderation effects of raveling on bleeding failure for both the roads and these models are validated on other two road sections. The study accentuates that there is no mediating effect of raveling on bleeding but it effects the bleeding moderately. These validated models can be surely used to find the bleeding failure, if ravelling parameters are known and hence, the survey time and cost can be minimized.
