Example Embodiment

[0041] Examples:

[0042] A construction method for super curing seal of cement concrete pavement, the steps are as follows:

[0043] S01: First of all, the construction site needs to be traffic controlled, and obvious and eye-catching warning and no-go signs should be set up at the two ends of the specified distance on the construction site;

[0044] To clean up and clean the old road surface, first polish the dirt and oil on the road surface with a grinder, and then use a small blower and washing machine to clean the road surface, so that the road surface is clean and free of dirt; the original road surface has a larger porosity Or when the water permeability is too high, avoid washing with water and use high-pressure air blowing to clean;

[0045] To clean up the cracks on the old road surface, first remove the debris and dust in the cracks, and then use the bonding material to fill the joints. The bonding material is a mortar mixed with high-content emulsified asphalt and fine san...

Abstract

The invention discloses a construction method for a super maintenance sealing layer of a cement concrete pavement, and relates to the technical field of road construction, in order to solve the technical problem that a maintenance and construction period is long after pavement is damaged in the prior art. The technical scheme of the construction method is characterized by stirring super cement, cement, water and sand at a construction site to manufacture a super cement sealing layer mixture, then pouring the super cement sealing layer mixture onto a damaged pavement, and flattening the pavement, thereby forming a super cement sealing layer on the damaged pavement. Through adoption of the construction method, in comparison with conventional road cement, the super cement sealing layer is short in setting time and quick in molding, thereby greatly shortening 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...
