Problems solved by technology

At present, the commonly used repair method for asphalt pavement cracks is to cut grooves along the cracks, pour hot asphalt, seal the cracks and prevent water from entering the interior of the pavement along the cracks, but the strength of the existing repair methods is too low, and secondary cracking is prone to occur

Embodiment 1

[0043] see Figure 1-2 , an embedded repair method for asphalt pavement cracks, comprising the following steps:

[0044] S1. Determine the size of the slot according to the size of the crack, and expand the slot through the slotting machine, and the width is not less than 1cm;

[0045] S2. First, use a high-power blower or hot air gun to blow out the sundries in the seam for 1-2 times, and then use a special hook to clean a small amount of debris and sundries in the groove. Manual cleaning, after cleaning, blow it again to ensure that the seam is absolutely dry and clean;

[0046] S3. Use the embedding tool to evenly excavate a plurality of fusion embedding holes through the molten asphalt on the two side walls of the crack, and reserve the pre-embedded magnetic suction ball 4 in the fusion embedding holes, and pull out the embedding holes after the asphalt is cooled and solidified tool;

[0047] S4. The seam filling material is prepared on site and mixed with an appropriat...

Abstract

The invention discloses an asphalt pavement crack embedded repairing method, and belongs to the technical field of asphalt pavement construction. The method comprises the following steps of: after expanding a crack, uniformly digging a plurality of fusion embedding holes in two side walls in the crack through molten asphalt by using a hole embedding tool, and reserving pre-embedded magnetic ballsin the fusion embedding holes; then preparing a joint sealing material on site, mixing a proper number of chemical force soft rods to be injected into the cracks after being mixed to be uniform, forcing the chemical force soft rods to partially enter the fusion embedding holes to be combined with the pre-embedded magnetic attraction balls through the magnetic attraction effect of the pre-embeddedmagnetic attraction balls on the chemical force soft rods, and foring high-strength combination of the cracks and an original asphalt pavement after the joint sealing material is cured; when the crackis extruded, the downward pressure of the chemical force soft rod is converted into the extrusion of the pavement on the two sides of the crack to the center, so that the pressure can be effectivelycounteracted, secondary cracking at the crack can be prevented, and the crack repairing strength is greatly improved.

Description

technical field [0001] The invention relates to the technical field of asphalt pavement construction, in particular to an embedded repair method for cracks in asphalt pavement. Background technique [0002] Asphalt pavement refers to various types of pavement paved with asphalt materials mixed with mineral materials. Asphalt binder improves the ability of paving aggregates to resist road damage from driving and natural factors, making the road smooth, less dusty, impermeable and durable. Therefore, asphalt pavement is the most widely used high-grade pavement in road construction. [0003] The asphalt structural layer of asphalt pavement itself belongs to the category of flexible pavement, but in addition to flexible materials, the base layer can also use rigid cement concrete or semi-rigid hydraulic materials. [0004] Asphalt pavement is various types of pavement formed by paving and rolling asphalt concrete. Asphalt concrete is a mixture formed by fully mixing asphalt m...
