截至2021年,中国公路养护总里程达到525万公里。超薄罩面作为最常用的路面养护技术之一,可以显著提高路面的经济效益和环境效益。为了促进超薄罩面的低碳发展,本文主要研究了超薄罩面几种功能性的作用机理及影响因素。首先,对超薄罩面的抗滑性能、降噪性能、抗车辙性能和抗裂性能进行了评价。结果表明,优质集料可使超薄罩面的抗滑和抗车辙性能提高5 %~20 %。优化后的级配及改性胶结料可将超薄罩面的噪音降低0.4~6.0 dB。高粘度改性胶结料可使超薄罩面混合料的抗车辙性能提高10 %~130 %。玄武岩纤维可使超薄罩面的抗裂性提升20 %以上。由于超薄罩面具有更薄的厚度及更好的道路性能,其基于性能的工程成本与传统罩面相比,可降低30 %~40 %。其次,研究了超薄罩面的几种环保功能,包括融雪除冰、废气降解和路面降温。由于超薄罩面的厚度较薄,有利于氯化物融雪材料向路表的扩散。因此,自融雪超薄罩面的融雪效果较好。此外,含有光催化材料的超薄罩面混合料可以分解20 %~50 %的尾气污染物。彩色超薄罩面最高能够将路面温度降低8.1 ℃。而含有热阻材料的超薄罩面的上下表面温差最高可达12.8 ℃。此外,本文总结了功能型超薄罩面在全世界的一些典型工程应用。本综述有助于研究人员更好地理解超薄罩面的功能性,同时可促进未来多功能低碳道路养护的实现。

Billet optimization can greatly improve the forming quality of the transitional region in the isothermal local loading forming (ILLF) of large-scale Ti-alloy rib-web components. However, the final quality of the transitional region may be deteriorated by uncontrollable factors, such as the manufacturing tolerance of the preforming billet, fluctuation of the stroke length, and friction factor. Thus, a dual-response surface method (RSM)-based robust optimization of the billet was proposed to address the uncontrollable factors in transitional region of the ILLF. Given that the die underfilling and folding defect are two key factors that influence the forming quality of the transitional region, minimizing the mean and standard deviation of the die underfilling rate and avoiding folding defect were defined as the objective function and constraint condition in robust optimization. Then, the cross array design was constructed, a dual-RSM model was established for the mean and standard deviation of the die underfilling rate by considering the size parameters of the billet and uncontrollable factors. Subsequently, an optimum solution was derived to achieve the robust optimization of the billet. A case study on robust optimization was conducted. Good results were attained for improving the die filling and avoiding folding defect, suggesting that the robust optimization of the billet in the transitional region of the ILLF was efficient and reliable.
