Single-component polyurethane tunnel pavement structure
The invention provides a single-component polyurethane tunnel pavement structure, and particularly relates to the technical field of road engineering. The single-component polyurethane tunnel pavement structure is sequentially provided with a base layer, a rubber powder modified asphalt macadam sealing layer and a pavement layer from bottom to top, the base layer is formed by paving cement stabilized macadam or cement concrete, and the rubber powder modified asphalt macadam sealing layer is formed by paving rubber powder modified asphalt and macadam. The pavement layer is sequentially provided with a polyurethane mixture bearing layer, a polyurethane mixture anti-rutting layer and a polyurethane mixture noise reduction layer from bottom to top, and cementing materials of the polyurethane mixture bearing layer, the polyurethane mixture anti-rutting layer and the polyurethane mixture noise reduction layer are all single-component polyurethane. According to the invention, the single-component polyurethane is used as the cementing material of each layer in the pavement layer, so that asphalt smoke is avoided, safety and environmental protection are realized, the noise reduction performance, flame retardance and rutting resistance of the tunnel pavement structure are improved, and the application prospect is good.
本发明提供了一种单组分聚氨酯隧道路面结构，具体涉及道路工程技术领域。本发明单组分聚氨酯隧道路面结构由下至上依次设置有基层、橡胶粉改性沥青碎石封层和铺装层，基层采用水泥稳定碎石或水泥混凝土铺设而成，橡胶粉改性沥青碎石封层采用橡胶粉改性沥青和碎石铺设而成，铺装层由下到上依次设置为聚氨酯混合料承重层、聚氨酯混合料抗车辙层和聚氨酯混合料降噪层，聚氨酯混合料承重层、聚氨酯混合料抗车辙层和聚氨酯混合料降噪层的胶结料均为单组分聚氨酯。本发明利用单组分聚氨酯作为铺装层中各层的胶结料，既避免了沥青烟的产生，安全环保，又提高了隧道路面结构的降噪性能、阻燃性能和抗车辙性能，具有良好的应用前景。
