• Description:
  Early opening strengths for concrete vary greatly around the country for many different reasons. DOTD specifies early opening strengths and will benefit from understanding the latest thinking and practices adopted by similar agencies. Knowing the best approach can lead to dependable concrete, increased use of travel lanes, and a reduced cost in the concrete mixture used. The current opening specification for full-depth patching of jointed concrete pavement (JCP) and for patching of continuously reinforced concrete pavement is 3000 psi or 72 hours. For partial depth patching of JCP, the specification is 3200 psi. The current specifications are based solely on compressive strength and are not necessarily based on the mechanics of materials.
