摘　　要：沥青路面拱胀病害已成为我国西北地区常见的路面病害之一。因此,对沥青路面拱胀病害的研究成果进行了综述,系统地总结了该种病害的特征、形成机理和主要影响因素。研究结果表明,沥青路面拱胀病害主要源于温度作用下,半刚性基层中产生的温度应力超过了其临界抗压强度,使得基层拱起并发生开裂,进而将沥青面层拱起,最终表现为路面拱胀。拱胀病害通常以全幅拱起的形式出现,拱胀宽度一般为20~200 cm,间距为50~200 m,拱胀高度通常为1~5 cm。该病害多发于温度较高的夏季,影响拱胀病害形成的主要因素包括温度、含盐量、级配类型、水泥剂量(质量分数)、施工季节和摊铺方式。基于现有研究,后续工作可以进一步探讨拱胀病害的形成机理,划分拱胀病害的严重程度,并深入分析多因素耦合作用对拱胀病害的影响。该研究成果可为预防与处置沥青路面拱胀病害提供更为有效的理论依据和实践指导。Blow-up disease of asphalt pavement has become one of the common pavement diseases in northwest China.Therefore,a review was conducted on the research results of asphalt pavement arch expansion disease,the characteristics,formation mechanism,and main influencing factors were systematically summarized.The research results indicate that the cause of the disease is mainly that the temperature stress generated in the semi-rigid base layer exceeds its critical compressive strength,causing the base layer to blow up,and the expansion of the asphalt pavement under the temperature effect.The expansion disease usually occurs in the form of a full arch,with a width of 20~200 cm,spacing of 50~200 m,and a height of 1~5 cm.This disease is more common in the hot summer.And the main factors affecting the formation of expansion disease include temperature,salt content,grading type,cement dosage(mass fraction),construction season,and paving method.Based on existing research,The formation mechanism of blowing-up diseases,classify the severity of arch expansion diseases,and deeply analyze the impact of multiple factors coupling on blowing-up diseases can be deeply explored in future.This research result can provide more effective theoretical basis and practical guidance for the prevention and treatment of blowing-up disease of asphalt pavement.
