Description
本发明涉及一种沥青路面半刚性基层病害现场快速再生修复方法。The invention relates to a rapid on-site regeneration and repair method for asphalt pavement semi-rigid base disease.
目前，我国80％以上的沥青路面基层和底基层采用了半刚性材料。半刚性基层虽具有较高的强度和承载能力，但在使用过程中，其强度、模量会由于干湿、冻融循环及在反复荷载的作用下因疲劳而逐渐衰减。因其固有缺陷，半刚性基层的局部损坏不可避免而又易发多发，而实际养护管理中的修复对策并不多。通常通过开挖方式进行维修，即除去己破损的松散基层和底基层，修整垫层后，重新铺筑基层和面层。该维修方法，一方面原路面材料遭废弃，无法再利用，再铺筑新料，导致维修成本高；另一方面，铺筑新的半刚性基层材料，需要长时间养生，造成交通拥堵，甚至引发交通安全事故。At present, more than 80% of asphalt pavement bases and subbases in my country use semi-rigid materials. Although the semi-rigid base has high strength and bearing capacity, its strength and modulus will gradually attenuate due to dry-wet, freeze-thaw cycles and fatigue under repeated loads during use. Due to its inherent defects, local damage to semi-rigid bases is inevitable and prone to frequent occurrences, but there are not many repair countermeasures in actual maintenance management. It is usually repaired by excavation, that is, the damaged loose base and subbase are removed, and the base and surface are re-paved after the cushion is repaired. In this maintenance method, on the one hand, the original pavement materials are discarded and cannot be reused, and new materials are paved, resulting in high maintenance costs; cause traffic accidents.
为减少施工对交通和社会的影响，近来有施工单位采用快硬快凝混凝土或贫混凝土等材料进行修复。但上述修复材料与原半刚性基层的黏结性较差，界面处易在车辆荷载作用下脱开，从而引起修复基层和面层的下陷。此外，上述材料与原基层材料相比，弹性模量大许多，可能导致修复结构自身的横向断裂，进而导致面层产生病害，如龟裂和破碎等。因此，选择一种方法简单，对交通影响小，并实现原路面材料现场环再用，质量优异的维修方法十分必要且急迫。In order to reduce the impact of construction on traffic and society, some construction units have recently used materials such as fast-hardening and fast-setting concrete or lean concrete for repairs. However, the above-mentioned repair materials have poor adhesion to the original semi-rigid base, and the interface is easily detached under the action of the vehicle load, which causes the subsidence of the repair base and surface. In addition, the elastic modulus of the above-mentioned materials is much larger than that of the original base material, which may lead to the transverse fracture of the repaired structure itself, and then cause the surface layer to have diseases, such as cracking and breaking. Therefore, it is necessary and urgent to choose a maintenance method that is simple, has little impact on traffic, and realizes on-site recycling of the original pavement materials.

The method is energy-saving and environment-friendly, and contributes to the realization of the national goal of "carbon neutrality and carbon peak".
(2)破碎的石料，与乳化沥青拌和后，表面被沥青裹附，回填开挖病害处，形成大空隙乳化沥青混合料，浇筑地聚物或快硬水泥浆液，将形成半柔性基层。其弹性模量相较于水泥混泥土等材料大幅较小，抗压强度约5～10MPa，与半刚性基层接近。不会因为模量差异，导致修复材料后期产生断裂等问题。(2) After the broken stone is mixed with emulsified asphalt, the surface is covered with asphalt, and the excavated diseased area is backfilled to form a large-void emulsified asphalt mixture, and geopolymer or rapid hardening cement slurry is poured to form a semi-flexible base. Its elastic modulus is much smaller than that of cement concrete and other materials, and its compressive strength is about 5-10MPa, which is close to that of semi-rigid base. It will not cause problems such as fracture of the repair material in the later stage due to the difference in modulus.
(3)为增加修复材料与原路面半刚性基层在界面处的粘接力，在铺筑材料前，在界面处喷洒界面粘接剂碱性水玻璃溶液。该材料可以激发回填材料与原路面材料中的石料、水泥和砂土等含有的硅铝基活性物质，如SiO

2O

(3) In order to increase the adhesion between the repair material and the semi-rigid base layer of the original pavement at the interface, before paving the material, spray the interface adhesive alkaline water glass solution at the interface. This material can stimulate the chemical reaction between the backfill material and the silicon-aluminum-based active substances contained in the stone, cement and sand in the original pavement material, such as SiO 2 and Al 2 O 3 , so that the new material and the original pavement pass through the interface. Chemical bonding to avoid cracking and peeling at the interface of traditional maintenance methods.
(4)本发明施工方法简单，无材料运输、拌合站拌和等环节，直接在施工现场路拌，节省施工时间和成本。且地聚物及快硬水泥材料可快速形成强度，避免传统材料的长时间养生，最大程度减少因道路维修对交通的影响。(4) The construction method of the present invention is simple, without material transportation, mixing station mixing and other links, and can be mixed directly on the construction site, saving construction time and cost. Moreover, geopolymers and rapid hardening cement materials can quickly form strength, avoid the long-term curing of traditional materials, and minimize the impact on traffic due to road maintenance.
