• Abstract:
  Most of the damage to concrete pavement results from poor drainage, which can lead to increased freeze-thaw damage, and when combined with heavy loading can contribute to cracking, spalling and surface damage that causes driver discomfort from increased roughness of the roadway. Open graded base courses compact less tightly than dense graded courses and consequently drain better. ; Many designs with OGBC call for stabilizing the upper portion of the OGBC with asphalt or cement. If these methods can reduce drainage problems and offer enough support to improve the service lives of concrete pavements and delay rehabilitation or replacement needs, OGBC may prove a more cost-effective way to deliver excellent concrete pavements to Wisconsin drivers. However, it can cost nearly an additional $100,000 per mile to use OGBC, so its life-cycle cost and performance must be carefully considered
