Embodiment

[0042] A cement concrete pavement super maintenance sealing layer construction method, the steps are as follows:

[0043] S01, first of all, it is necessary to control the traffic on the construction site, and set up conspicuous warning and prohibition signs at both ends of the specified distance from the construction site;

[0044] To clean and clean the old road surface, firstly, the dust and oil stains on the road surface are polished with a grinder, and then the road surface is cleaned with a small hair dryer and a washing machine, so that the road surface is clean and free of dirt; the porosity of the original road surface is relatively large Or when the water permeability is too high, avoid washing with water, and use high-pressure air blowing to clean;

[0045] To clean the cracks on the old pavement, first remove the sundries and dust in the cracks, and then fill the joints with a bonding material, which is a mortar made of high-content emulsified asphalt and fine sand...

Abstract

The invention discloses a cement concrete pavement super maintenance sealing layer construction method, relates to the technical field of road construction, and aims to solve the technical problem in the prior art that the maintenance and construction period is long after the pavement is damaged. Create a super cement sealer mix by mixing super cement, cement, water and sand, then pour the super cement sealer mixture over the damaged pavement and pave it evenly to form a super cement seal on the damaged pavement, due to Compared with ordinary road cement, the super cement seal layer has a shorter setting time, and the super cement seal layer is formed quickly, which greatly shortens the construction period.

Description

technical field [0001] The invention relates to the technical field of road construction, more specifically, it relates to a construction method of a cement concrete pavement super maintenance seal. Background technique [0002] Cement concrete pavement, as one of the main pavement types used by roads at all levels in my country, has the advantages of high rigidity, high strength, good durability, and daily maintenance workload, and occupies a considerable proportion in my country's road network; because the concrete strength reaches the design The strength has a certain age, so the maintenance time is longer, which often causes serious interference to road traffic. Therefore, strengthening preventive maintenance is especially important for cement concrete pavement. [0003] When the cement concrete pavement in the prior art is damaged in a large area, the maintenance measure is to first cut the damaged area plate with a cutting machine to separate it from the surrounding pla...
