Description
The two objectives for this research were to review the 2016 asphalt mixture specifications to determine whether changes were warranted that could lead to more durable asphalt mixtures and, if so, adjust the specification accordingly and construct test sections to evaluate the revised specification.

Description
Colorado Department of Transportation (CDOT) has dynamic modulus (E*), and flow number (N) database of different mixes from different regions of Colorado. The sensitivities of these mixes considering factors such as mix types, aggregates source, volumetric properties, contractors, preparation times, binders, etc. on E*, and N, and on the pavement performances are investigated in this study.

Description
Full depth reclamation of asphalt pavements using asphalt emulsions is a process that recycles and rejuvenates the existing asphalt pavement surface, base, and sometimes, the subgrade, providing an improved underlying structure for the new asphalt pavement. This report provides guidance, standardized plans and specifications, construction inspection best practices materials testing procedures and frequencies, a performance evaluation process, and...

Description
Crack sealants are often utilized as a preservation tool in asphalt pavements. When a hot mix asphalt overlay is placed on top a pavement containing crack sealants, a bump and additional transverse cracks sometimes occur in the new asphalt overlay. These bumps and sometimes, transverse cracks are initiated during breakdown rolling and become progressively more severe upon further compaction. This paper presents results of a five-year study designed...
