摘　　要：分析了新型封缝材料的应用现状,借鉴国内外有关标准,结合机场道面工程特点,在试验研究的基础上,提出了机场混凝土道面新型封缝材料技术要求。结果表明:流平性、弹性恢复率、拉伸模量、浸水后定伸粘结性、浸油后定伸粘结性、冷拉—热压后粘结性、质量损失、抗燃性8项指标能有效控制道面封缝材料质量与现场施工质量,保证道面的设计与使用要求,延长道面使用寿命。This paper analyzes the present situation of the new type of sealing materials used in airport concrete pavement, by using the correlative standards both inland and abroad for reference, combined with the environmental characteristics of airport pavement engineering and based on the analysis and experiments, finally brings forward the technical requirements for the new type of sealing materials. After the application of the eight technical requirements to six airports, the results show that these requirements - flow, elastic recovery, tensile modulus, adhesion/cohesion properties at maintained extension after immersion in water / oil, adhesion / cohesion properties at variable temperatures, change in mass and burning resistance - can availably master the material quality and construction quality, ensure the requirements for pavement design and use, prolong the pavement service life.
