Bridge pavement and maintenance construction method
The invention discloses a bridge pavement, and belongs to the field of bridge deck pavement, the bridge pavement comprises a pavement and a pavement layer, the pavement layer is located above the pavement, the bridge pavement further comprises a wearing layer, the wearing layer is located above the pavement layer to isolate the pavement layer from the external environment, the thickness of the wearing layer is 3mm-8mm, the wearing layer is formed by mixing aggregate with the single particle size of 3mm-5mm and modified emulsified asphalt, and the modified emulsified asphalt is a mixture of modified emulsified asphalt and modified emulsified asphalt. The wearing layer is constructed at normal temperature, the thickness is only 5 mm, and the manufacturing cost is relatively low; the single particle size of the aggregate is 3mm-5mm, and the aggregate is not filled with fine aggregate after being formed, so that gaps are developed, and accumulated water on the road surface can be quickly drained; the road surface structure depth is improved, the anti-skid performance is improved, and the driving safety is improved; the modified emulsified asphalt has excellent high-temperature stability, and high-temperature diseases such as ruts and flooding can be avoided; the wearing layer is directly paved on the pavement surface of the original steel bridge deck, materials of the original pavement layer are isolated from the environment, wheels and the like, and the degradation of the materials of the original pavement layer and the expansion speed of diseases are delayed. The invention further relates to a bridge pavement maintenance construction method.
本发明公开了一种桥梁路面，属于桥面铺装领域，包括路面以及铺装层，铺装层位于路面上方，桥梁路面还包括磨耗层，磨耗层位于铺装层上方使铺装层与外部环境隔绝，磨耗层厚度为3mm‑8mm，磨耗层由单粒径为3mm‑5mm的集料与改性乳化沥青混合形成，磨耗层为常温施工，且厚度仅为5mm，造价相对低；集料单粒径为3mm‑5mm，成型后无细集料填充，因而空隙发育，能够迅速排除路表积水；提高路表构造深度，增大抗滑性能，提高行驶安全性；改性乳化沥青具有出色的高温稳定性，能够避免车辙、泛油等高温病害；磨耗层直接铺筑于原钢桥面铺装表面，将原铺装层材料与环境、车轮等隔绝，延缓了原铺装层材料的劣化及病害的扩展速度。本申请还涉及一种桥梁路面养护施工方法。
