| 摘要： | After a concrete pavement is placed, a period of time is required for the concrete to gain strength. The pavement can be opened to traffic only after it has achieved adequate strength. Various criteria have been used for opening concrete roadways to traffic. Most criteria are based on the accumulated judgment of specifying agencies or other authorities. Little or no engineering analysis exists to substantiate most opening-to-traffic criteria currently in use. Rational criteria for opening concrete pavements to traffic are presented. On the basis of Miner's hypothesis of accumulated fatigue, flexural strength opening criteria are presented for concrete roadways (municipal and highway) subjected to construction and public traffic. The criteria are appropriate for new construction, reconstruction, and concrete overlays except bonded concrete overlays. |
