Abstract:
In order to clarify the temperature field distribution and variation characteristics of rubberized concrete pavement, continuous monitoring of temperature information in the field of rubberized concrete pavement was established base on fiber Bragg grating test technology. The temperature field variation characteristics of rubberized concrete pavement in early age(0 to 4 d)and long term(9 to 84 d)were studied. Ordinary concrete pavement was taken as the control group, the effect of the addition of rubber particles on the long-term temperature field of concrete pavement was analyzed. Based on the temperature distribution statistics, the frequency distribution characteristics of the temperature fields of rubberized concrete pavement and ordinary concrete pavement were investigated. The results show that in the first and second stages of early-age temperature variation, the exothermic hydration is the main factor affecting the temperature of rubberized concrete pavement. At the time of zero-stress temperature of rubberized concrete pavement, the temperature at the middle of pavement slab is higher than those at the top and bottom of the pavement slab, and the temperature gradient of pavement slab is -12.0 ℃/m. In the curing stage of the concrete, the negative temperature gradient will lead to warpage and curing residual stress of rubberized concrete pavement. The long-term monitoring results show that the addition of rubber particles reduces the sensitivity of concrete to temperature change, and significantly increases the temperature at the middle of the slab of concrete pavement in the temperature-fall period. The maximum daily average positive temperature gradient of the rubberized concrete pavement is 6.85 times that of the ordinary concrete pavement, while its maximum daily average negative temperature gradient is only 51% that of the ordinary concrete pavement. In a temperature change cycle(24 h), the daily temperature curve of the rubberized concrete pavement shows obvious asymmetry, and the cooling time is twice the heating time. The results of the temperature distribution statistics show that the addition of rubber particles can effectively reduce the frequency of negative temperature gradient in the concrete pavement. Especially for the temperature gradient less than -10 ℃/m, the frequency of rubberized concrete pavement is 20.4% lower than that of ordinary concrete pavement. In other words, rubber particles can effectively reduce the warping of concrete due to negative temperature gradients, which facilitates the construction of large-size concrete pavement.3 tabs, 13 figs, 29 refs.
