A tunnel pavement water seepage treatment method

The invention provides a tunnel pavement water seepage treatment method. By chiseling away an asphalt concrete surface layer, the objective of determining a water seepage location or range can be achieved, so that water seepage treatment can be performed in a targeted manner; by using blind drains for guiding drainage and by taking the measures of waterproof plates and waterproof concrete for water isolation, seeping water is prevented from returning backward and upward to the asphalt concrete surface layer; after pavement water seepage treatment, a pavement is free of seeping water, and the overall appearance and running comfort are not influenced; the construction process is simple and technological quality control is not difficult; machines, tools and apparatuses required by the construction are mostly simple and required materials are easy to purchase; during construction, a water seepage site can be located directly; with blind drains guiding drainage and the waterproof plates and the waterproof concrete
