Manila hemp, also known as abacá, is a type of buff-colored fiber obtained from Musa textilis (a relative of edible bananas), which is likewise called Manila hemp as well as abacá. It is mostly used for pulping for a range of uses, including speciality papers. It was once used mainly to make Manila rope, but this is now of minor importance. Abacá is an exceptionally strong fibre, nowadays used for special papers like teabag tissue. It is also very expensive, priced several times higher than woodpulp. Manila envelopes and Manila paper take their name from this fibre.

The tape has a high strength in the machine direction and does not break during production and processing processes. In addition, the tape has a nonwoven fabric substrate and thereby excels also in punching quality. The tape is therefore particularly useful as a double-sided pressure-sensitive adhesive tape for fixing a wiring circuit board.

Subgrade paving structure and construction method for highway extension
The invention discloses a roadbed paving structure for highway extension and a construction method of the roadbed paving structure for the highway extension. The roadbed paving structure for the highway extension comprises a cushion layer, a lower base layer, an upper base layer and a surface layer, wherein a fixing frame is arranged between an intermediate layer and a gravel layer to increase thebonding strength of the upper base layer and the lower base layer so as to prevent hierarchical separation, furthermore, the cushion layer is located at the bottom layer, thereby being capable of enhancing the structure stability and dispersing the roadbed stress to prevent sinking, a traction part is arranged between the surface layer and the upper base layer to increase the bonding strength between the layers so as to prevent the surface layer from being separated, wherein one or more of steel wires, manila hemp fibers, carbon fibers and polytetrafluoroethylene fibers are arranged inside the traction part, therefore the materials are combined to make the traction part tough and corrosion-resistant, and then the traction part is not easily corroded by cement, and in addition, the problemof weak adhesive force of the polytetrafluoroethylene fibers and the cement or asphalt is solved. A connecting part is further arranged and comprises a plurality of dovetail grooves and clamping blocks adapted to the dovetail grooves, the dovetail grooves and the clamping blocks are respectively arranged on a joint surface of an old road and the roadbed structure to prevent a newly widened roadbed from sinking or cracking or separating relative to the old road.
