AC - MMA based on MMA resin as raw materials, adding suitable amount of fiber, high strength aggregate, and mixed with various additives as specially for the pavement repair MMA polymer airport pavement rapid repairing materials. For different pavement, bridge expansion joints, concrete and asphalt pavement damaged need to quickly open traffic areas such as super patching material, its 40 minutes fast curing, construction convenience, durability, weather resistance, appearance, etc have all the advantages of pavement patching material, a permanent benefit for repair, more than 40 degrees below zero in winter also can rapid solidification, greatly shorten the scene of the closed time.
Ò» . Material characteristics
1. Can be in the temperature of minus 40 degrees to 50 degrees above freezing under construction and fast curing, all the year round to construction;
2. The construction is simple, health quickly, within 40 minutes to 1 hour after construction can pass;
(3) and concrete, asphalt, hollow plate, steel plate, all the basis of objects can be very good adhesion;
4. Anti-uv function is strong, do not fade, not aging for a long time;
5. With super wear-resistant, resistant to chemicals, durable performance;
6. It has strong compressive strength, bending, and corrosion resistance;
7. Have excellent particle bridging function, construction, don't need the other set connection does not occur crack;
8. Have good water tightness, strong waterproof ability;
9. The resin structure tightly, strong adhesion, can be maintained and the base surface adhesion, not as easy as epoxy resin stripping;
10. Has the high strength wear resistant, good impact resistance;
11. Don't water absorption and winter does not exist the phenomenon such as freezing and thawing or strength;

Èý . Construction procedure
1. Pit slot base: clean float ash on the surface of the base, impurities and water;
2. The bottom coating: according to the situation to choose the proper coat and uniform coating roller brush;
3. The MMA polymer airport pavement rapid repairing materials evenly stirring, then on the curing agent fully mix pour into a clean up good pit slot, quick swab with plaster knife in the repair flat repair material;
4. The mixture ratio of mixture with 13 to 15 grams per kilogram of curing agent, a bucket with a bag of curing agent, mixing must be uniform, such as on the curing agent ratio incorrect or inadequate stirring can cause not curing adverse outcomes;
5. Finishing tool, using the specified solvent to clean the tools used, etc.;
ËÄ. Matters needing attention
1. Summer curing speed faster, need to speed up the construction;
2. Start shall be used for curing repair material;
3. Repair parts are strictly prohibited during curing.
4. After the construction with the specified solvent cleaning tool use, should be stored in a window;
5. Homework personnel outside the forbidden children and idle people contact;
