- Abstract
- Through field surveys and evaluation on several widened concrete pavements, issues on construction and design related problems are broken down into three categories to be discussed; poor smoothness, influence of traffic vibration on concrete curing, and poor connection to the existing pavement. There are many places where about 100mm only of the marginal strip is removed and where defects such as widening and faulting are observed. Also cracks arise again from the patched areas due to stress concentration near the joint. Roughness on the widened concrete pavement was evaluated and there are some stations where the smoothness limit is over passed. For design consideration, shortage of the required force in the tie-bar is expected in case of road widening specially from 3 lanes to 4 lanes. Finally the average pull-out force of specimens made from the current practice was about 57% of the required force. New connecting methods were suggested in this study.
