水泥混凝土桥复合结构环氧沥青粘结层性能研究

Study on Epoxy Asphalt Adhesive Layer Properties of Compound Structure of Cement Concrete Bridge

桥梁结构与柔性铺装层之间的粘结层,对桥面结构起着至关重要的作用。因此,有必要对水泥混凝土桥面用环氧沥青粘结层的性能进行研究。该文阐述了其剪切试验和拉拔试验。通过试验,证明其具有优异的力学性能,能提高水泥混凝土桥面和沥青混凝土之间的粘结,有效地抵抗路面行车的影响,从而提高整个桥面的铺装质量。

The adhesive layer between the bridge structure and the flexible paving layer is very important to the deck structure. Therefore, it is necessary to study the properties of epoxy asphalt adhesive layer used for the cement concrete deck. The article sets forth its shear test and drawing test. These tests prove that it has the excellent mechanics property, and can improve the adhesion between cement concrete deck and asphalt concrete and efficiently withstand the influence of pavement driving so as to improve the paving quality of the whole deck.
