ABSTRACT
ABSTRACT: This paper presents a preliminary analysis of an ongoing long-term thermal segregation study of asphalt mixtures in Connecticut. This study monitors about 40 sites that were constructed between 2000 and 2003. Several factors examined throughout this study were combined with the use of a thermographic camera to provide further insight as to the material properties as well as the practical application of asphalt pavement construction. This paper discusses five pavement sections on Route 94 that were constructed with and without the use of an MTV. The sections are compared in terms of roughness and cracking data collected by automatic road analyzer (ARAN) between the construction in 2002 and year 2007. The performance data shows a qualitative and quantitative benefit of usage of the MTV in the construction. Sections constructed with the aid of an MTV displayed a significant reduction in transverse cracking as well as roughness.
