Problems solved by technology

In the traditional road pavement construction method, the construction of the pavement decorative surface layer depends on manual leveling and finishing, and the tools (spatula, etc.) are easy to stick glue, cannot be washed, and the work efficiency is low
I have never seen cast-in-place construction with dry and hard mortar, because cast-in-place construction cannot achieve good bonding of the two-layer structure, and it is easy to cause phenomena such as delamination

Embodiment 1

[0020] A construction method of pavement pavement, including the construction of the structure layer and the construction of the facing layer, the mixture formed by fully stirring the binder, the aggregate of 10-20mm particles, and water is spread within 2 hours Lay it on the working plane to be paved, and vibrate or flatten it as the bottom layer of the structure through the vibrating concrete of the flat plate;

[0021] For the construction of the facing layer, the virtual paving is first carried out, and the facing layer binder is mixed with the decorative materials such as aggregates with 0.1-1mm particles to form a mixture, and the facing layer material is mixed with a round rod with a diameter of 6-26mm. laid on the structural layer;

[0022] Solid paving: use 15-20kg cylindrical rollers with surface roughness < 10 microns for initial pressure leveling, after 15-20 minutes use 30-50 kg cylindrical rollers with surface roughness < 10 microns for re-pressing and leveling, ...

Embodiment 2

[0026] A construction method for a pavement pavement layer, comprising the construction of a structural layer and the construction of a facing layer, a mixture formed by fully stirring a cement binder, sandstone aggregates of 5-10mm particles, and water in 1 - 2.5 hours to pave on the working plane to be paved, vibrated and leveled by vibrating concrete or flattened as the bottom layer of the structure;

[0027] For the construction of the facing layer, the virtual paving is first carried out, and the epoxy resin binder of the facing layer is mixed with the facing materials such as sand and gravel aggregates with 0.1-3mm particles to form a mixture, and a round rod with a diameter of 6-26mm is used Lay the finishing layer material on the structural layer;

[0028] Solid paving: use 15-20kg cylindrical rollers with surface roughness < 10 microns for initial pressure leveling, after 15-20 minutes use 30-50 kg cylindrical rollers with surface roughness < 10 microns for re-pressin...

Abstract

The invention discloses a road surface paving layer construction method which comprises construction on a structure layer and construction on a facing layer. The construction on the facing layer comprises the following steps: performing virtual paving on the facing layer, mixing facing layer materials, and paving the facing layer materials on the structure layer by adopting a round bar with the diameter of 6-26mm; performing initial pressure flattening by adopting a cylindrical roller, performing re-pressing flattening within 15-20 minutes, and performing final pressure flattening within 30-60 minutes. According to the thin-layer construction method for the road surface paving layer, manual operation is replaced by sticks and other equipment, the paving efficiency is high, and the operation is convenient and rapid. Meanwhile, the virtual paving thickness and the compaction thickness are effectively controlled, and accurate and high-quality construction is realized. The facing layer and the structure layer are well adhered, and a layered phenomenon is avoided. The road surface paving layer obtained by adopting the construction method is solid, flat and smooth.

Description

technical field [0001] The invention relates to a road surface construction method, in particular to a road surface pavement construction method. Background technique [0002] The pavement pavement layer includes the bottom structural layer and the upper finishing layer. The structural layer is composed of cement or epoxy resin binder and coarse aggregate, and the finishing layer is composed of binder and finer aggregate. material composition. Adhesives for the facing layer are cement-based, epoxy resin, polyurethane, etc. In the traditional road pavement construction method, the construction of the road pavement decorative surface depends entirely on manual smoothing, and the tools (spatula, etc.) are easy to stick to glue, cannot be washed, and the work efficiency is low. I have never seen cast-in-place construction with dry and hard mortar, because cast-in-place construction cannot achieve good bonding of the two-layer structure, and it is easy to cause phenomena such...
