Fiberglass Geogrid for Pavement Reinforcement:
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 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,
and seawalls.
Properties:
1) High tensile strength: the strength-to-weight ratio of fiberglass is greater
than that of plain carbon steel. At 20o C, the ratio of its elastic
modulus to that of asphalt concrete is 20:1. Thus it is strong enough to
prevent deflection cracks.
2) 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%.
3) 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.
4) 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.
5) Wide temperature range: the melting point of fiberglass is 1000C, while that
of hot asphalt is 160C. 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
100o C. 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.
6) 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.
7) 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. 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.
