摘要:

复合道面注浆工程由于沥青混凝土面层材料模量随温度变化而变化,因此传统的FWD 弯沉评价方法无法适用。本研究依托上海某4E 机场跑道复合道面注浆工程,基于有限元数值模拟方法,提出了对实测弯沉数据进行荷载修正和温度修正的理念,并给出了详细的修正方法,得到了基于FWD 弯沉测试的适用于复合道面注浆工程效果评价的方法。工程验证表明,评价方法能够满足复合道面注浆工程效果评价的需要。

关键词: 复合道面, 注浆, FWD, 荷载修正, 温度修正

Abstract:

FWD deflection evaluation methods can not be applied to composite pavement grouting engineering as the asphalt concrete material modulus changes with temperature. Based on a composite pavement grouting engineering of a Shanghai 4E airport,a calculation method for load modification factor and temperature modification factor is proposed,meanwhile,a method for composite pavement grouting effect evaluation based on FWD deflection test is obtained. Engineering example shows that this method can meet the needs of composite pavement grouting effect evaluation.

Key words: composite pavement, grouting, FWD, load modification, temperature modification
