Study on the S-RAFC M ultiplex Pavement M aterial

Abstract

Abstract: A new type of semi-rigid pavement material called S-RAFC is introduced, whose pe rformance is between that of the cement concrete and that of the asphalt concrete.The crumbly coeficient(Ra/crt)is from 3 to 5，and it call satisfy the requirements of diferent pavement structures in enduring pressure by adjusting the dosage of special additive and the gradation. Test road validates that the S-RAFC，so a new type of multiplex pavement material，owns better using perform ance through its sample experiment inside.

Key words: road material, cement-based, emulsified asphalt, crumbly coefficient, multiplex mate al, pavement

To further study its influence mechanism and to solve the problem of limited accuracy of traditional prediction methods under multi-feature data conditions, a pavement skid resistance performance assessment model based on the fusion of Bayesian optimization algorithm (BOA) and extreme gradient boosting (XGBoost) was proposed. Firstly, specimens phalt mixtures of different gradation types were prepared. Friction data and 3D texture data of the specimen surface were respectively obtained by using a pendulum friction meter and a 3D laser scanning device. Secondly, the height, the wavelength and shape parameters were extracted to describe the texture structure, and the texture feature importance analysis was carried out to clarify the factors that significantly affected the skid resistance. Then, the optimal key parameters were improved by introducing of the model BOA-XGBoost and the prediction model of skid resistance performance was established. The research results show that compared with the comparative models, the proposed model has higher accuracy, with a correlation coefficient R2 of 0.890 6, which is 25.2%, 13.0%, and 15.1% higher than those of the comparative models, respectively. The proposed model can effectively correlate texture features with pavement skid resistance performance. [J]. Journal of Chongqing Jiaotong University(Natural Science), 2025, 44(6): 35-44.
