LLRD sealant produced by our company is a reliable and durable highway maintenance material. It is widely applied to the crack treatment of cement and asphalt pavements, edge crack pouring of burying traffic detection induction system. It is also used to the repairing of manhole cover, secondary paving joint of road surface, seamless bridge and other construction environments.

1. Water resistance: Sealant material is insoluble in water, and it can effectively
stop the penetration of moisture and prevent "water penetration" from damaging road surfaces;
2.Cohesiveness: Good cohesiveness ensures the firm adhesion with road surface when the road
expands with heat and contracts with cold or suffers immersion;
3.Malleability: The sealant fluid can deform and extend with crack stretching to ensure full adaptation
to the deformation force of sealant fluid caused by "Thermal heat stress";
4.Hot melting: Sealant fluid belongs to construction material, and the material in the tank
can be used repeatedly heating;
5.High temperature stability: In a hot summer, LLRD sealant fluid will not be melted when being heated
and will not pollute the road surface because vehicle wheels carries it;
6.Low temperature flexibility: In a cold winter, LLRD sealant fluid would not get brittle and fail in performance,
but it will continuously maintain its flexibility.
This product is made of the modified asphalt and recycled rubber bits. It is of solid shape,which is very easy to use with employing sealant heating furnace. During the heating process, asphalt and rubber would react and form a kind of elastic and viscous mixture which can effectively seal asphalt and cement road surface cracks. Products made from asphalt of medium softness, used in the circumstance where summer temperature seldom surpasses 40 ℃ and winter temperature is seldom under - 5 ℃.MBS modified asphalt, rubber powder and other ingredients have great cohesiveness and could seal the cracks firmly. Due to containing of too much rubber, it is very sticky when using, and could not achieve self-compacting.
We recommend you to abide by the regulations of sealant LLRD-2050's specifications. You should also follow the requirements of ASTMD5078 when testing
Before use, the operator must read about the specifications of asphalt rubber heating construction, asphalt rubber reinforcement and Polly sealants, to choose the correct & suitable product and heating method, and also to know road surface preparation work and matters needing attention and safety procedures. Each glue has these directions
Packaging are cartons: each box has mucous membrane, very convenient in mobility. Products' weight is no more than 20 kg per case; Prices of the product are according to the net weight. The cartons are consist of carton boards, minimum testing standard is 350psi(241N/square centimeter); Using water-proof cartons; Sealed with adhesive tapes and having no pins. Each carton has label, product name, model number, specifications and standards, operating temperature and safety instructions
We guarantee that, the sealant products meet the ASTM & AASHTO standards and other related standards when delivered to you. Cracks, joints of cracks and technical preparation work before the seal does not belong to guarantee scope, therefore, our company is not responsible for improper use or misuse of sealants, please consult our sales staff before buying
