Pavement reinforcement with geosynthetics are nowadays a
vital part of road construction. Due to continuously
increasing traffic and thermal fluctuations, roads become
stressed which leads to its damage and hampers habitat
losses.
It increases the requirement of pavement
maintenance adding to whole life costs and carbon footprint.
There are many pavement reinforcement solutions
(discussed below) which can be treated with geosynthetics
and aids in enhancing pavement life.
It can be achieved with the usage of ATBIAXIAL
(PP) (PP) in base/sub-base layer to increase the design life of pavement or
reducing the pavement thickness. The aperture allows interlocking with soil particles and binds
it at its position which
forms a rigid base thereby strengthening the pavement. Geotextiles (ATGTX) also play a important role in
subgrade.
ATBIAXIAL (PP) (PP) is
manufactured with high quality of polypropylene by punching and drawn method. It is designed for
different grades providing higher tensile resistance at lower elongations.
ATGTX is a permeable geotextile which when used in association with soil, have the ability for separation, filtration, protection and drainage. Raw material used for ATGTX is generally polypropylene or polyester.
Drainage of water from pavements has always been an important consideration in road design. Geocomposite drain acts as conduit for the movement of liquid or gases in its plane. ATDRAIN is a geocomposite drain produced by sandwiching drainage layer (geonet) between two ATGTX layers. Because of two material ATDRAIN performs various functions such as drainage, filtration, separation, barrier and protection.
With conventional method of asphalt road construction, high stress concentrations at the crack tip result in crack propagation that penetrates into the top asphalt surface layer. Asphalt reinforcement turns vertical crack stresses into horizontal direction for better dissipation. A&T provides solution for that with Glass grid and Paving Fabric.
Glass grid comprises of fiberglass strands coated with elastomeric polymer that imparts high tensile strength to the road if laid between levelling course and surface course in asphalt overlay.
Paving Fabric is made by non-woven geotextile coated with bituminous layer which acts as a moisture barrier and stress relieving membrane between existing pavement and asphalt overlay and extends the service life of the overlay.
