Embodiment 1

[0025] Embodiment 1 The preparation process of grout sealant slurry comprises the following steps:

[0026] (1) Dry mix carbon black and non-expandable sodium bentonite at a ratio of 2kg:99kg, and mix evenly to obtain P material.

[0027] (2) Mix material P, latex, and water at a ratio of 100 kg: 40 kg: 100 kg, and use paddle stirring or turbine stirring at a stirring speed of 20-80 rpm to obtain material J.

[0028] (3) Stir and mix J material with emulsified asphalt, fine aggregate, and silica sol at the ratio of 225 kg: 160 kg: 500 kg: 125 kg to obtain grout seal layer slurry.

[0029] The construction process of the grout seal layer slurry obtained by the grout seal layer slurry production process refers to: the grout seal layer slurry is sprayed by a pressurized spraying device with a nozzle diameter greater than 3mm and a pressure of 1.25MPa, or Carry out manual scraping construction directly according to the conventional method.

Embodiment 2

[0030] Embodiment 2 The preparation process of grout sealant slurry comprises the following steps:

[0031] (1) Dry mix carbon black and non-expandable sodium bentonite at a ratio of 3kg:99kg, and mix evenly to obtain P material.

[0032] (2) Mix material P, latex, and water at a ratio of 100 kg: 50 kg: 100 kg, and use paddle stirring or turbine stirring at a stirring speed of 20-80 rpm to obtain material J.

[0033] (3) Stir and mix J material with emulsified asphalt, fine aggregate, and silica sol at a ratio of 225 kg: 170 kg: 600 kg: 125 kg to obtain grout seal layer slurry.

[0034] The construction process of the grout seal layer slurry obtained by the grout seal layer slurry preparation process is the same as that in Example 1.

Embodiment 3

[0035] Embodiment 3 The preparation process of grout sealant slurry comprises the following steps:

[0036] (1) Dry mix carbon black and non-expandable sodium bentonite at a ratio of 2kg:99kg, and mix evenly to obtain P material.

[0037] (2) Mix material P, latex, and water at a ratio of 100 kg: 40 kg: 100 kg, and use paddle stirring or turbine stirring at a stirring speed of 20-80 rpm to obtain material J.

[0038] (3) Stir and mix J material with emulsified asphalt, fine aggregate, and silica sol at a ratio of 225 kg: 180 kg: 700 kg: 125 kg to obtain grout seal layer slurry.

[0039] The construction process of the grout seal layer slurry obtained by the grout seal layer slurry preparation process is the same as that in Example 1.

Abstract

The invention relates to a making process for grout layer-sealing slurry. The process comprises the following steps: (1) subjecting carbon black and non-expandable sodium-based bentonite to dry and uniform mixing in proportion so as to obtain a P material; (2) uniformly mixing the P material with latex and water in proportion under stirring by blades or a turbine so as to obtain a J material; and (3) uniformly mixing the J material with emulsified bitumen, fine aggregate and silica sol in proportion under stirring so as to obtain the grout layer-sealing slurry. The invention also discloses a construction processes for the grout layer-sealing slurry. The processes are simple; and the prepared grout layer-sealing slurry has substantial effect, and can resist water, supplement light oil ingredients lack in an old pavement and fill in fine cracks without reducing the frictional force of an original pavement.

Description

technical field [0001] The invention relates to the field of medium and above-traffic pavement maintenance, in particular to the preparation and construction technology of grout sealing layer slurry. Background technique [0002] In an era dominated by the concept of "replacing maintenance with construction", road maintenance was placed in a secondary position. With the exposure of insufficient maintenance, the thinking of road management gradually moved closer to "equal attention to construction and maintenance", and the road maintenance ratio rose in one fell swoop to 2012 97.2%, the era of full road maintenance has come. However, the traditional maintenance methods have gradually exposed various problems, such as: high noise at the micro-surface, insufficient aesthetics of the road surface, and poor durability of the fog seal layer. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a grout sealing layer slurry ...
