Embodiment Construction

[0034] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0035] refer to figure 1 , is a kind of asphalt pavement construction method disclosed by the present invention, comprises the following steps:

[0036] Step 1: Preparation before construction: remove the soil and sundries on the original road surface and repair the pits and depressions;

[0037] Step 2: preparation and planning for poisonous gas absorption: carry out paving area planning on the road surface to be paved with asphalt, divide the area with 20 meters as the length of the area to be paved with asphalt, and the width of the road as the width of the area to be paved with asphalt. A support 1 is arranged on the long side of the asphalt area to be paved, the length direction of the support 1 is consistent with the length direction of the asphalt area to be paved, and a plurality of high-pressure suction fans 2 are evenly distributed along the length...

Abstract

The invention relates to an asphalt pavement construction method, and belongs to the technical field of road construction. The method comprises the steps of 1, conducting preparation before construction, specifically, removing soil and sundries on an original pavement and repairing pot holes and pits; 2, preparing and planning toxic gas absorption; 4, conducting slurry seal construction, specifically, using modified emulsified asphalt prepared on site, mixing 2%-3% of ordinary Portland cement with the strength of 42.5 grade, then paving the mixture on a construction pavement, and turning on ahigh-pressure suction fan in advance before paving; 5, conducting prime coat oil and tack coat oil construction, specifically, spraying prime coat oil on the pavement base layer, and spraying tack coat oil between asphalt concrete layers; and 6, conducting construction of an asphalt concrete lower surface layer and an asphalt concrete upper surface layer, specifically, after the spraying of primecoat oil passes inspection and acceptance, mixing an asphalt mixture on site, and immediately paving after the mixing is completed. The construction method has the advantage of reducing toxic gas inhaled by constructors in the construction process of the asphalt pavement.

Description

technical field [0001] The invention relates to the technical field of road construction, in particular to an asphalt road construction method. 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. [0003] In the hot summer, during the asphalt pavement construction of the prior art, the construction personnel always inhale the steam of the high-temperature asphalt mixture and the exhaust gas discharge...
