Abstract

The invention discloses an asphalt concrete pavement construction process based on a target mix ratio, which comprises the following steps: laying asphalt concrete on the road surface by a paver, thereby forming an asphalt concrete layer on the roadbed; intermittently setting up multiple rows of deformation on the asphalt concrete layer Sections, each row of deformation sections is intermittently provided with multiple sets of deformation holes; rubber material and wear-resistant agent are added to the heating chamber of the melting tank according to the weight ratio of 90-100:5-6 for heating, and rubber fillers are obtained. Then, according to the distance of the deformation holes on each row of deformation sections, the distance between the connecting pipes on the drip irrigation mechanism is adjusted through the spacing adjustment mechanism; 1. The bottom pipe enters the discharge pipe, and is discharged from the discharge pipe and falls into the deformation hole on the asphalt concrete layer to solidify and form; the invention is easy to operate, and the asphalt concrete road surface is not prone to vehicle slippage in winter.

Description

technical field [0001] The invention belongs to the technical field of construction, and relates to an asphalt concrete pavement construction technique, in particular to an asphalt concrete pavement construction technique based on a target mix ratio. Background technique [0002] Asphalt concrete is a mixture made by mixing asphalt and a certain proportion of aggregate, and is now widely used in road paving. [0003] The comparative document CN109987881A discloses an asphalt concrete and a preparation method thereof, which belongs to the field of asphalt concrete, and solves the problem that the asphalt concrete needs to consume a lot of energy for heating during transportation and heat preservation. Asphalt concrete includes 5-25 parts of asphalt, 15-82 parts of fine aggregate, 50-170 parts of coarse aggregate, 2-15 parts of external admixture, 6-36 parts of thermal insulation component, 10-69 parts of thermal conductivity component, EVA hot melt 3-15 parts of glue; the th...
