Embodiment Construction

[0021] The technical solution of the present invention is further described below, but the scope of protection is not limited to the description.

[0022] A construction method for asphalt pavement, comprising the following steps:

[0023] S1, set the base layer of the pavement, and carry out leveling work, then carry out construction measurement and construction stakeout, use the tensioner along the width of the pavement on both sides of the pavement every 10 meters to release the construction elevation 0.5 meters away from the paving boundary and the middle point, The steel wire datum line is suspended on both sides, and a slide bar is added at the middle point to control the paving elevation;

[0024] S2, mixing the asphalt concrete, controlling the heating temperature of the asphalt to 140-160°C, the heating temperature of the stone to 150-170°C, and controlling the factory temperature of the mixed asphalt concrete to 150-160°C;

[0025] S3, the transportation of mixed as...

Abstract

A construction method of asphalt pavement is provided. the invention sets the construction process and the construction parameters of the asphalt pavement in detail, the pavement is smoother and denser than other asphalt pavements today, with good anti-loosening, corrosion and segregation resistance, As that crack in the pavement is avoided, the service life and the safety of the pavement is improved; At the same time, due to the effective distribution of the whole working procedure, the construction time can be greatly saved, and through the temperature control of the mixture, the waste of raw materials caused by the material transportation and the construction process can be greatly reduced, and the laying cost of the asphalt pavement can be saved.

Description

technical field [0001] The invention belongs to the technical field of road construction, and in particular relates to a construction method of 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. 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. At present, asphalt pavement has been more and more applied to urban road construction. Since the conventional asphalt pavement construction methods often have the problems of poor quality ...
