Rope made of asphalt hemp

Bitumen hemp rope, construction features and functions of hemp fibers

Asphalt hemp rope, also known as asphalt hemp strand, is a convenient and quick material for filling and waterproofing to prevent corrosion, popular due to its simplicity in installation and affordability. Made from jute that has been soaked in asphalt for a long time, it boasts better corrosion resistance and is commonly used for filling construction joints and concrete sealing.

The role of asphalt hemp rope, asphalt hemp shives, asphalt hemp fibers, and asphalt hemp flocking is: Materials with waterproof properties are called oil-soaked hemp fibers, which play a role in filling, waterproofing, and anti-corrosion in expansion joints. Asphalt hemp shives, fibers, and flocking are obtained by heating asphalt to dissolve it and then mixing it evenly with hemp, serving as filling materials for road joints, settlement joints, and expansion joints.

Production Process

Soak sisal rope and sisal fibers in an emulsified asphalt pond for 24 hours, then add antioxidant expanders, preservatives, and other materials to act as sealant, waterproofing, and anti-corrosion in expansion and settlement joints. The general process for asphalt sisal fibers, asphalt sisal strips, and asphalt sisal wadding is: clean and dry the deformation joints, fill with oil sisal fibers, pour emulsified asphalt, and then remove the excess asphalt after curing and cooling.

Cautionary Notes

Prior to the asphalt fiber fill seam construction, ensure all debris and standing water within the expansion joints are completely cleared, followed by filling the expansion joints with asphalt fiber.
