Problems solved by technology

The reason is that the anti-reflection cracks and high-temperature stability of common modified asphalt mixtures cannot meet the requirements of the airport pavement, especially the use environment of the apron.
[0004] In the prior art, binders and binders are used at high temperatures, and hot mix asphalt mixture production, paving, and compaction will generate high energy consumption and exhaust emissions, which will cause serious environmental pollution

Embodiment 1

[0028] (1) Cement concrete pavement disease treatment

[0029] Firstly, investigate the disease type and damage degree of the cement concrete pavement slab, remove the pavement with a large damaged area and serious degree, cut and break it, and clean up the waste. Secondly, brush the binder on the excavated pavement interface. Thirdly, normal-temperature thermosetting modified asphalt concrete is used for backfill paving, and plate compactors are used for vibratory rolling. Finally, the normal temperature thermosetting modified asphalt mixture was maintained by using the heating wall of the heat regeneration maintenance vehicle, and the maintenance time was 25 minutes.

[0030] (2) Milling and cleaning of cement concrete pavement

[0031] First, use a milling machine to mill the cement concrete pavement with a milling depth of 50mm; secondly, use a sweeper and blower to remove milling residue and moisture to ensure that the milled cement pavement is in a clean and dry state....

[0041] Firstly, investigate the disease type and damage degree of the cement concrete pavement slab, remove the pavement with a large damaged area and serious degree, cut and break it, and clean up the waste. Secondly, brush the binder on the excavated pavement interface. Thirdly, normal-temperature thermosetting modified asphalt concrete is used for backfill paving, and plate compactors are used for vibratory rolling. Finally, the normal temperature thermosetting modified asphalt mixture was maintained by using the heating wall of the heat regeneration maintenance vehicle, and the maintenance time was 45 minutes.

[0042] (2) Milling and cleaning of cement concrete pavement

[0043] First, use a milling machine to mill the cement concrete pavement with a milling depth of 40mm; secondly, use a sweeper and blower to remove milling residue and moisture to ensure that the milled cement pavement is in a clean and dry state....

Embodiment 3

[0051] (1) Cement concrete pavement disease treatment

[0052] Firstly, investigate the disease type and damage degree of the cement concrete pavement slab, remove the pavement with a large damaged area and serious degree, cut and break it, and clean up the waste. Secondly, brush the binder on the excavated pavement interface. Thirdly, normal-temperature thermosetting modified asphalt concrete is used for backfill paving, and plate compactors are used for vibratory rolling. Finally, the normal temperature thermosetting modified asphalt mixture was maintained by using the microwave heating wall of the heat regeneration maintenance vehicle, and the maintenance time was 55 minutes.

Abstract

The invention discloses a thin-layer asphalt overlay construction and joint treatment method for an airport parking apron cement pavement. The asphalt overlay structure comprises a cement concrete pavement, a thermosetting modified asphalt macadam sealing layer and an asphalt concrete overlay layer from bottom to top. The method comprises the following steps: (1), treating cement concrete pavementdiseases; (2), milling and planing the cement concrete pavement; (3), performing construction of a thermosetting modified asphalt macadam sealing layer; (4), constructing a cover surface layer; and (5), performing cover surface layer joint cutting and joint pouring construction. Binding materials adopted in the step (1), the step (3) and the step (4) are normal-temperature thermosetting modifiedasphalt of different formulas, and joint sealing materials adopted for joint sealing are silicone sealants. The binding materials are used at normal temperature, so that the energy consumption and waste gas emission during production, paving and compaction of the hot-mixed asphalt mixture are greatly reduced, and the environmental pollution is reduced.

Description

technical field [0001] The invention relates to the field of infrastructure construction, in particular to an environment-friendly asphalt structure and a construction method thereof. Background technique [0002] The airport pavement is the most important infrastructure in the airport flight area, and it undertakes important tasks such as aircraft take-off and landing, taxiing and parking. Peeling, pockmarked surface and cracked board corners, broken seams, aging and failure of joint fillers and other diseases, which lead to increased operating costs and reduced comfort of the aircraft. In order to ensure flight safety, pavement damage must be repaired in time. [0003] In order to solve pavement diseases and improve pavement performance, asphalt thin layer overlay technology is used for structural reinforcement or functional recovery of old airport concrete pavement. Many domestic airport concrete pavements have applied asphalt overlay technology ,having lots of experien...
