浅谈EPS轻质填料的特性与应用

在软弱地基上修筑公路，路基的沉降和桥头差异沉降将直接影响工程质量和运营安全，EPS以其具有超轻质、较强化学稳定性等优良特点作为一种新型填料，在软弱地基路堤填筑中逐渐被推广利用。结合上海市北松公路（车亭公路-沪闵路段）改建工程中EPS填料的应用实例，介绍EPS的特性以及在公路拓宽工程和桥头高填路堤中的应用，阐述了施工中的技术要点。

Discussion on Characters and Application of EPS Light-weight Filler

For road construction on soft ground, ground settlement and bridgehead difference settlement directly affect the project＇s quality and operating safety. As a new filler which has the characters of super lightness and strong chemical stability, EPS is being widely used in road embankment filling on soft ground. In light of the EPS fillers＇ application in Beisong Road （Cheting to Humin section） reconstruction project, this paper introduces the EPS＇s characters and its application in road widening project and high filling road embankment at bridgehead, as well as the technical keys during construction.. It is hoped that this technology can achieve a wider use.
