Dowel alignment can be measured efficiently and accurately using MIT Scan-2, a state-of-the-art nondestructive testing device for measuring and recording the position and alignment of dowel bars (FHWA 2005; Yu and Khazanovich 2005). The device is easy to use, the...
Improper placement of dowel bars can lead to reduced load transfer between slabs, which results in pavement distresses such as faulting and spalling at joints. To determine the accuracy of dowel placement by Dowel Bar Inserter (DBI), the Nebraska Department of Roads...
An adequate longitudinal joint tie bar system is essential in the overall performance of concrete pavement. If designed and installed properly, tie bars prevent the joints from opening and consequently improve load transfer efficiency between slabs and between slabs...
