Abstract:<\/strong><\/p>\n

Most of the Departments of Transportation in North America are shifting its focus from
\nthe construction of new roads to the maintenance and rehabilitation of existing
\nhighways. Every year thousands of kilometers of road are being maintained or
\nrehabilitated in North America. So, there is a necessity to look for appropriate
\nstrategies to maintain and rehabilitate the existing pavements. Many past studies
\nreported that the service life of overlay primarily depends on the interface bonding
\nbetween the existing pavement and overlay. In addition, the overlay fails predominantly
\ndue to lack of proper maintenance for existing pavement surface before constructing
\nthe overlay. In this paper, the Finite Element-based software program (ABAQUS) was
\nemployed to evaluate the interlayer damages between the existing pavement and
\noverlay. A Box\u2013Behnken Design (BBD) method is used to quantify the effects of
\nparameters such as the thickness of existing layer, thickness of the asphalt overlay,
\nmodulus of asphalt overlay, modulus of existing rigid layer, rate of tack coating and
\ntining type on the performance of the constructed overlay. From the analysis, it was
\nfound that, the performance of overlay predominantly depends on the strains inducing
\nat the interface between overlay and existing pavement due to traffic loads. Various
\ninterface conditions are modeled for evaluating the performance of the overlay. The
\nresults obtained from both the finite element analysis and BBD model could help in
\nselecting optimum tack coat application rate for existing pavement surfaces and for
\ndeveloping a sustainable overlay construction specification.<\/p>\n
