Glass Fiber Geogrid Introduction
There are several kinds of geogrids, of which glass fiber grille is
commonly used. There are layers of asphalt on the surface of glass
fiber grille, which is high temperature resistant, anti-aging and
corrosion resistant. Asphalt concrete pavement is widely used in
highway construction in China. However, the load stress will cause
serious damage to the asphalt concrete pavement and shorten the
service life of the highway.
Therefore, in order to improve the quality of asphalt concrete
pavement, measures should be taken to improve its stability. For
example, by increasing the application of geogrid, the quality of
asphalt concrete pavement can be effectively improved.

Glass Fiber Geogrid Features:
Sometimes, it is combined with self-adhesive pressure sensitive
adhesive and surface asphalt impregnation treatment to closely
integrate the grid and asphalt pavement. As the interlocking force
of earth and stone in the geogrid grid grid increases, the friction
coefficient between them increases significantly (up to 08 ~ 10).
The uplift resistance of geogrid embedded in soil increases
significantly due to the strong friction bite force between grid
and soil, so it is a good reinforcement material. At the same time,
geogrid is a kind of plastic plane mesh material with light weight
and certain flexibility. It is easy to cut and connect on site, and
can also be overlapped and overlapped. The construction is simple
and does not need special construction machinery and professional
technicians.
Glass Fiber Geogrid Application:
Relieve fatigue and cracking
The asphalt overlay on the old cement concrete pavement is mainly
used to improve the service function of the pavement, but has
little contribution to the bearing function. The rigid concrete
pavement under the overlay still plays a key bearing role. The
asphalt overlay on the old asphalt concrete pavement is different.
The asphalt overlay will be carried together with the old asphalt
concrete pavement. Therefore, asphalt overlay on asphalt concrete
pavement will not only appear reflection cracks, but also fatigue
cracks due to the long-term action of load. We make stress analysis
on the loading of the asphalt overlay on the old asphalt concrete
pavement: because the asphalt overlay is a flexible surface with
the same properties as the asphalt overlay, the road surface will
deflect under the load. The asphalt overlay in direct contact with
the wheel is under pressure, and in the area outside the wheel load
edge, the surface is under tension. Because the stress properties
of the two stress areas are different and close to each other, it
is easy to be damaged at the junction of the two stress areas, that
is, the sudden change of force. Fatigue cracking occurs under
long-term load.
Construction method Glass Fiber Geogrid
1. Preparation:
Complete all joint filling, pit filling, foundation reinforcement
and leveling layer laying.
2. Road surface condition
The road surface must be clean and dry with a temperature between 5
℃ and 60 ℃.
3. Product preparation
The self-adhesive glass fiber geogrid shall not be kept in a dry
environment to maintain its viscosity at the construction site.
