Highways and Roads Transportation Infrastructure
Highways and Roads are identifiable routes for vehicle traffic between two or more places. A Highway is classified as a main road, usually with a smooth, paved surface, that connects major towns or cities. Roads are typically paved in urban areas, but can be unpaved routes in more rural areas.
Pavement Rehabilitation is the resurfacing, restoration, and rehabilitation of existing pavement surfaces to extend its service life, improve performance and/or improve its structural capacity.
Lianyi Geocomposite are the ideal optimization for pavement rehabilitation. From large-scale motorway projects to local repair of secondary roads, and from airport runways to storage yards: Our interlayer products provide solutions which will improve the new asphalt overlay by securing a perfect cost-benefit ratio.
Keeping the existing road pavement inventory in a serviceable condition is one of the major challenges of road authorities world-wide. Therefore, the focus of attention is on maintenance techniques and rehabilitation methods which allow the working life of the basic road structure to be extended in a cost effective and technically reliable manner.
One method which has been successfully used world-wide for more than 30 years is the maintenance of asphalt and concrete roads using paving interlayers. This method represents an economical means of considerably increasing the maintenance intervals and thus the working life of the road.
Product introduction
BIAXIAL GEOGRID COMPOSITER is a composite made of bi-axial polypropylene (PP) geogrid, heat bonded to a long fiber non-woven polyester geotextile that acts as a filter and soil separator. This geogrid is manufactured using a punching and drawing process whereby the polypropylene sheet is stretched in two directions, machine (longitudinal) and cross-machine (transverse). The result is a monolithic and isotropic geogrid with thick and wide ribs, thick integral nodes, and uniform square apertures. Engineered to be mechanically and chemically stable in aggressive soil environments, THIS-GEOCOMPOSITE allows sub-base drainage to help maintain structural stability, and is very effective in keeping expensive imported material from being contaminated by migration of fines from the saturated base soils.
