Construction method for continuously laying structural layers of highway pavement

Abstract

The invention discloses a construction method for continuously laying structural layers of a highway pavement. The construction method comprises the following steps of: filling an earth-filled road foundation by layers, compacting by layers to finish all the constructions, carrying out quality test to be qualified, and continuously carrying out paving construction on a pavement underlayer; after all the constructions of the pavement underlayer are finished, carrying out quality test to be qualified, and continuously carrying out paving construction on a pavement base layer; after the all the constructions of the pavement base layer are finished, carrying out quality test to be qualified, continuously carrying out paving construction on a pavement surface layer; and finally, after all the constructions of the pavement surface layer are finished, strictly closing traffic, forming integral covering, heating and maintaining on the base layer and underlayer by naturally absorbing solar energy with black bituminous concrete of the surface layer, synchronously finishing safety construction, and opening traffic for use. According to the invention, integral maintaining is carried out after continuously laying and forming, thus the maintaining and forming of the underlayer and the base layer of the pavement are favorably accelerated, the construction times of the underlayer and the base layer of the pavement are effectively shortened, the construction working efficiency is increased, the construction cost is lowered and the maintaining cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of highway traffic infrastructure construction, and in particular relates to a construction method for continuous paving of highway pavement structural layers, that is, a construction method in which the highway pavement structural layers are first continuously paved and formed, and then the whole is naturally preserved. Background technique [0002] As we all know, to build a highway, the construction period is generally 3 years. In addition to the preliminary work of related projects such as survey and design, land acquisition and demolition, the construction period will take at least 18-24 months. Usually, the construction starts from the original ground, and goes through the process of measuring and setting out, filling the subgrade, laying the road, installing safety facilities, and planting greening. [0003] Filled roadbed is composed of pre-filling treatment layer and multi-layer filling layer. The c...

Problems solved by technology

[0008] "Technical Specifications for Construction of Highway Pavement Base Course" (JTJ034-2000) specifies the construction procedures for pavement subbase, base course, and surface course as follows: subbase paving construction——covering and moisturizing——basic paving construction——covering and moisturizing— — Surface layer paving construction; the construction period of this traditional technological process and health preservation is relatively long. The discontinuous construction between layers is likely to cause interlayer pollution or surface layer damage and affect the interlayer bonding. Covering layer by layer to moisturize and maintain health is not only a process Many and high cost; at present, with the continuous improvement of road mechanized construction level and modern construction management level, the quality assurance rate of road engineering construction is more stable, therefore, it is necessary to explore and innovate traditional construction methods
