Preventive maintenance super-viscous fine overlay for expressway and laying method of preventive maintenance super-viscous fine overlay
The invention relates to the technical field of highway maintenance, in particular to a preventive maintenance super-viscous fine overlay for an expressway and a laying method of the preventive maintenance super-viscous fine overlay for the expressway, the preventive maintenance super-viscous fine overlay comprises a high-altitude highway pavement and pavement diseases, the pavement diseases exist on the expressway pavement, and an emulsified asphalt binding material layer is laid on the expressway pavement. In the process of paving the ultra-viscous fine overlay, the emulsified asphalt binding material layer and the mixed aggregate layer are paved by adopting deep discharging operation, so that the emulsified asphalt binding material and the mixed aggregate are excessively discharged, and then the emulsified asphalt binding material and the mixed aggregate are flattened to a proper thickness by utilizing the slicking mechanism; the emulsified asphalt binding material and the mixed aggregate can be fully filled into the pavement disease, the situation that the emulsified asphalt binding material and the mixed aggregate are loosened at the pavement disease is avoided, and the compactness and the stability of the super-viscous fine overlay are effectively improved. The method has the advantage of effectively improving the compactness and the stability of the super-viscous fine overlay.
本发明涉及公路养护技术领域，具体涉及一种高速公路预防性养护超粘精罩面及其铺设方法，包括高度公路路面和路面病害，所述高速公路路面上有路面病害，所述高速公路路面上摊铺有乳化沥青粘结料层。本发明在超粘精罩面铺设的过程中对于乳化沥青粘结料层和混合骨料层的铺设均采用的是深度排料操作，将乳化沥青粘结料和混合骨料进行过量的排出，然后利用刮平机构将乳化沥青粘结料和混合骨料摊平到合适的厚度，可以使得乳化沥青粘结料和混合骨料充分的填充到路面病害内部，避免乳化沥青粘结料和混合骨料在路面病害处出现松散的情况，有效的提高超粘精罩面的紧实和稳定性。本发明具有有效的提高超粘精罩面的紧实和稳定性的优点。
