Description

Technical Field

[0001] The invention belongs to the technical field of micro-surfacing asphalt detection, and specifically relates to a micro-surfacing emulsified asphalt water seepage detection device and method. Background Art

[0002] Micro-surfacing, as an efficient pavement maintenance technology, has been widely used in the field of highway maintenance in recent years. It is a slurry mixture made of polymer-modified asphalt, aggregates, fillers, water and additives in a certain proportion. It is evenly spread on the road surface through special paving equipment to form a thin and solid wear layer. The characteristics of micro-surfacing are that it is quick to construct, low cost and effective. It can quickly close pavement cracks, improve the anti-skid performance of the pavement, reduce water penetration, and effectively extend the service life of the pavement. At the same time, micro-surfacing can also significantly improve the flatness and aesthetics of the road surface, and enhance driving comfort and safety.

[0003] Within 1 to 2 months after the completion of micro-surfacing construction, completion acceptance projects are required to ensure the actual working condition of the micro-surfacing after the completion of micro-surfacing construction. The inspection contents mainly include appearance, thickness inspection, anti-skid performance, noise test and water seepage rate inspection. The water seepage rate inspection mainly drips water onto the road surface through the dripping component, and the amount of water infiltrated into the road surface is detected within a certain period of time to calculate the water seepage rate, so as to ensure the normal use of the road in rainy and snowy weather.

[0004] At present, the method of water seepage detection is mainly to apply sealing waterproof material on the road surface, and then place the drip assembly on the sealing waterproof material to ensure that all water flows into the road surface. Although the above steps can complete the detection, there are still the following shortcomings: 1. The drip end of the drip assembly needs to be set in the middle of the sealing waterproof material to ensure that the seepage spreads from a point on the road surface as the center to the surrounding area. If it is set eccentrically, the seepage point will be inaccurate, affecting the calculation of the seepage rate.

[0005] 2. After the water seepage detection is completed, the sealing and waterproof materials are often sticky, and manual separation may damage the dripping components. Manual separation is also often difficult to remove the sealing and waterproof materials cleanly. Summary of the invention
