Construction Practices and its Effect on Bond Strength of Pavements
Extensive study is carried out to ascertain the effects of various construction practices on the bond strength between different layers of the pavement. In this study various construction practices refers to curing time of the pavement, various equipments used during construction of pavement, surface treatment provided. In this study a review is also carried out of the research work carried out by various researchers for estimating the bond strength between the existing old hot mix asphalt (HMA) layer and the new hot mix asphalt (HMA) layer overlaid. Also a review is taken in study regarding various experiments conducted by the researchers on the bond strength of different layers. Normally milling provides a good strength and good bond at the interface between the old layer and new layer overlaid on it. It is also observed that curing time has least effect on the bond strength.
