Asphalt pavement local damage impermeability repairing method

Abstract

The invention discloses an asphalt pavement local damage impermeability repairing method, and belongs to the field of pavement repairing. According to the asphalt pavement local damage impermeabilityrepairing method, when repairing a local damage part, an impermeable ball net is paved between cement paste and an asphalt layer, and in a rolling compaction process, on one hand, the pre-broken ballson the trailing impermeable balls are stressed and broken, and the waterproof coating inside the trailing impermeable balls permeates downwards into the lining net layer and fills the lining net layer so that a high-strength waterproof interlayer with a lining is formed, the impermeability of the repaired pavement is high, and the the situation that the overall pressure resistance becomes poor due to strength damage caused by water seepage in the pavement is effectively avoided, and the service life of the repaired pavement is obviously prolonged; on the other hand, the reinforcing tail and the extension connecting wires on the reinforcing tail are embedded into the cement paste so that the internal connecting strength of the cement paste can be effectively improved, large-area fragmentation is not likely to happen after the cement paste is heavily pressed, and the strength of the repaired asphalt pavement is further improved.

Description

technical field [0001] The invention relates to the field of pavement repair, and more specifically relates to a method for repairing local damage and impermeability of asphalt pavement. Background technique [0002] Asphalt pavement is various types of pavement formed by paving and rolling asphalt concrete. Asphalt concrete is a mixture formed by fully mixing asphalt materials with a certain viscosity and appropriate dosage and mineral aggregates of a certain grade. Asphalt concrete, as an asphalt pavement material, has to bear the repeated action of running vehicle loads and the long-term impact of environmental factors during its use. Therefore, while asphalt concrete has a certain bearing capacity, it must also have good durability against natural factors. That is to say, it should be able to show sufficient stability in high temperature environment, crack resistance in low temperature condition, good water stability, long-lasting anti-aging and good anti-skid property...

AI Technical Summary

Problems solved by technology

[0003] During long-term use, under long-term heavy pressure, and in heavy rainfall weather, it is difficult to discharge water from the drainage system in time, especially in relatively low-lying places, where the water accumulation is serious, and water seeps into Below the pavement, under long-term action, the strength of the asphalt pavement is easily affected, resulting in local damage to the asphalt pavement
