Evaluation of Pavement Crack Treatments – Hot Pour vs. Emulsified Materials
In cooperation with ConnDOT, FHWA and the Connecticut Cooperative Highway Research Program, the CAP Lab is investigating differences between crack treatment materials. Multiple test sections will be established using the different types of crack treatments. These test sections will be observed over a two year period with performance evaluations conducted in the winter and summer for both years. Additional pavements treated in previous years will also be evaluated as to the performance of the different crack treatments. James Mahoney, P.I. james.mahoney@uconn.edu
Long-Term Performance of Areas Exhibiting Thermal Segregation During Construction
In cooperation with ConnDOT and FHWA, the CAP Lab conducted a three year study using thermal imaging technology to evaluate hot-mix asphalt pavements for thermal segregation at the time of construction. GPS coordinates were obtained whenever possible at the location where the thermal image was taken. Currently, the CAP Lab is starting a project to follow these thermally segregated areas through their service life to document the effects to the longevity of the pavements due to thermal segregation at the time of construction.

Establish Subgrade Support Values For Typical Soils in New England
Cross section graphic of subgrade support materials The objective of this research is to develop typical values, or range of typical support values, for sub-grade soils found in New England region based on AASHTO soil classification. Dr. Ramesh Malla, P.I. ramesh.malla@uconn.edu
