FAST-TRACK PRODUCTS REVIEW: CONCRETE PAVEMENT PATCHING REPAIR MATERIALS

Following is a technical research report prepared by the research division on the subject of rigid pavement fast-track patching products and their lab and field testing. This report summarizes a six-year experimental field study conducted with assistance from the materials division. Comprehensive lab testing was conducted on various brands of product. Lab testing included compressive strength, slant shear bond test, and freeze/thaw testing. Field testing included nondestructive pavement testing with a Swiss hammer device. Also, two major experimental demonstration projects were constructed on Interstate 15 in Salt Lake county and in Davis county. Results from the lab and field testing proved that most products performed "excellent". A detail drawing of recommended construction installation is included for reference.
