Detailed Product Description

This product is a new highway pavement reinforcement base material
that is manufactured using continuous coating fiberglass.

It is characterized by high tensile strength in both axial and
lateral directions, low stretch rate, alkali-resistance, high
temperature-resistance, as well as convenience in construction
and low price. It can be used on pitch pavement, bituminous
concrete pavement and cement pavement to prevent cracks occurring
and prolong pavement service life. It also can be used as a basal
reinforcement material for hillsides, reservoirs, harbors,
ports, water channels, seawalls, etc.

Properties:
8)High tensile strength:The strength-to-weight ratio of fiberglass
is greater than that of plain carbon steel.At 20^oC, the
ratio of its elastic modulus to that of asphalt concrete is 20:1.
Thus it is strong enough to prevent deflection cracks.
9)Low elongation:The fiberglass grid stress diagram shows as a
vertical straight line, which indicates that its ability of
deforming resistance is very high and its break elongation is less
than 4%.
10)Creep resistance:Fiberglass grid is not subject to creep,
unlike many other materials. When bearing a load for long periods,
fiberglass grid will not permanently deform.
11)Chemical compatibility with surfacing materials:Fiberglass
grid is coated with an inorganic sizing that makes it chemically
compatible to all the materials used in surfacing mixes.
12)Wide temperature range:The melting point of fiberglass is
1000^oC, while that of hot asphalt is 160^oC.
Therefore, fiberglass grid is unaffected by the highest
temperatures experienced in road surfacing. It is also unaffected
by low temperatures and retains its strength in temperatures as
low as -100^oC.Unlike other materials such as carbon fiber,
Kevlar fiber, steel rib and plaster fiber, the elastic modulus of
fiberglass is not affected by temperature change.
13)Physical and chemical stability:Fiberglass grid is treated with
special inorganic sizing that makes it very resistant to physical
wear and a wide range of corrosive environments created by chemical,
biological and climatic changes.
14)Nesting, interlock and restraint effects:Asphalt road mix extrudes
through the holes of grid, thereby forming a nesting and interlocking
mechanism that restrains movement of the mix. This allows for improved
loading bearing capability and greater dimensional stability. An asphalt
road mix reinforced with fiberglass grid, which acts as a frame in the surfacing materials, forms a monolithic construction similar to steel reinforced concrete.
