Characteristics of Jointed Plain Concrete Pavement (JPCP) Built-in Temperature in Different Climate Conditions
To understand the characteristics of early-age built-in temperature in JPCP, the actual data of construction climate conditions of typical regions in China were investigated. Based on the application of early-age JPCP temperature numerical simulation program, built-in temperature characteristics of early-age pavement in typical regions was analyzed. The results show that the pavement constructed in different climate conditions produce difference characteristics of early-age built-in temperature due to geographical distinction. Positive built-in temperature difference of JPCP is larger in the regions which have difference in temperature between day and night or higher solar radiation intensity, while the negative built-in temperature difference isn’t influenced obviously by different regions and paving conditions. The maximum positive (negative) built-in temperature difference generally appears in pavement constructed in hot summer. The air temperature is the major factor affecting built-in basic temperature. The higher air temperature, results in the higher built-in basic temperature (temperature in slab bottom) is.
