Performance of Pavement Temperature Prediction Models

Abstract: Appropriate asphalt binder selection is dependent on the correct determination of maximum and minimum pavement temperatures. Temperature prediction models have been developed to determine pavement design temperatures. Accordingly, accurate temperature prediction is necessary to ensure the correct design of climate-resilient pavements and for suitable pavement overlay design. Research has shown that the complexity of the model, input variables, geographical location among others affect the accuracy of temperatu… Show more

“…This could have affected the prediction accuracy of these models. The R 2 and RMSE values produced for Kumasi by the Diefenderfer [11] model compared well with Lekea and Steyn [27] findings, where an evaluation of the Diefenderfer [11] model in Pretoria yielded R 2 of 0.378 and RMSE of 4.6 °C. However, higher R 2 and RMSE values were recorded by the Diefenderfer [11] model for Tamale than Pretoria [27].…”

However, higher R 2 and RMSE values were recorded by the Diefenderfer [11] model for Tamale than Pretoria [27]. As seen in Figure 11, the Taamneh [12] model-predicted pavement tem sus measured pavement temperature is scattered above the LOE, indicati errors between the predicted and measured temperatures.…”

“…The most frequent bitumen grade utilized in asphalt mixtures in this region is the asphalt binder 60/70 penetration grade for Marshall mixtures [11]. However, the Super-pave Performance Grading (PG) system appropriately takes into account the pavement conditions as it links the measured physical qualities of asphalt binders with field performance [12,13]. Although other elements, such as the geographic location, also play a significant influence, air temperature has the greatest impact on pavement temperature.…”

“…However, the recommendation from [11] included asphalt binder of PG 64-10 for Oman with 95% dependability. The environmental factors affect the engineering properties [9,13,14,16,17]. This paper reports the results of an experimental investigation regarding the performance of asphalt mixtures using asphalt binder with 60/70 penetration grade and PG 64-10.…”
