一、Product Introduction

A high-performance pavement repair material developed specifically for repairing functional layers on concrete surfaces. Mainly used for apron, cement pavement, workshop pavement, airport runway and other base layers that are intact but have carbonized and worn surface functional layers; And restorative repairs such as surface damage, peeling, and pulverization caused by freezing can extend the service life of the apron pavement. This product is made by processing various polymer materials, special cement, and selected aggregates, combined with a complete set of construction methods to ensure the restoration of the original pavement function.

二、Main characteristics

Easy to construct, simply mix with an appropriate amount of water to pour and apply;

Fast construction speed, high economic benefits, and shortened construction period;

High early strength, can be put into use within 4-5 hours after construction;

Good adhesion performance: The coating has strong adhesion and excellent bonding performance when bonded to concrete and mortar. Resistant to frost and sulfate corrosion, non-toxic and non corrosive;

Good crack resistance: able to adapt to the deformation of concrete base without cracking or falling off. There is no cracking, peeling or peeling phenomenon during thin layer repair;

Can be used in damp substrates and environments, and can be used as repair materials.

Rapid repair of military port and dock construction facilities;

Rapid repair of industrial and civil building facilities.

五、Usage

Before construction, ensure that the construction base in the construction area is solid, clean, free of oil stains, floating dust, loose objects, and other stains;

Use mechanical or manual methods to chisel and groove the construction base surface, and rinse the construction base surface clean with water;

Apply two coats of penetrating interface agent, and the interface agent layer should penetrate and absorb into the base layer to be constructed, achieving semi dry and non accumulating shell formation;

Mix the mortar slurry according to the recommended water to material ratio of 1:0.14-0.16. When mechanically mixing, the mixing time should be 5-6 minutes;

Fill the repair area with scraper, small shovel, and plaster;

Use plaster to compact and level from the center to the edge of the repair area;

Wet and cover with geotextile in a timely manner during final setting.

六、Precautions

During summer construction, the mortar should be protected from direct sunlight and covered with a damp geotextile for moisture retention and curing; During winter, attention should be paid to insulation and maintenance. Hot water mixing and covering with rock wool blankets can be used for insulation. Construction cannot be carried out on rainy days or when the temperature is below 5 ℃ and the wind speed is above level 5;

Storage: Store in a dry and cool place, ensure ventilation, and avoid direct sunlight;

Under normal storage conditions, the storage period is 90 days. If it exceeds 90 days, it must be verified through testing before use.
