Evaluation of Saw and Seal over the Overlaid Existing Concrete Joints.

摘要

The objective of this study is to evaluate what effect a sawed and sealed joint in asphalt has on controlling reflective cracking from an existing concrete joint. In 1994 the NDDOT constructed a test section comprised of 54 sawed and sealed joints constructed over existing concrete joints. The section were installed immediately after a four-inch hot bituminous asphalt pavement was applied over the surface of the existing concrete. The performance of the test section will be evaluated, by the NDDOT, for a period of five years.
