  • TenCate Mirafi® HPa Subgrade Stabilization for Container Yard for Infinity Logistics, Westport, Klang

    Westport, Klang Malaysia

    Overview:
    In South East Asia, infrastructure developments increasingly involved construction over soft soils. Soft soils commonly formed by alluvial deposition in a lake or sea environment, poses great challenges and difficulties from the infrastructure construction point of view.

    Pulau Indah is home to Westport, Malaysia. The general subsoil in this area is made up of very soft marine clay to depths of more than 30m, the water table is almost at ground level and the subgrade comprises a dessicated crust layer of the marine clay formation. At this project site, a stable load
    supporting platform was required for container handling and stacked storage.

  • TenCate Mirafi® HP Subgrade Stabilization - Long Beach Port, California USA

    Long Beach Port, USA

    Overview:
    The Port of Long Beach is the second busiest container seaport in United States. To meet constantly growing demand to handle cargo form Asia it was necessary to expand container terminal capacity.

    This project consisted of building a new wharf at Per G to expand the international Transportation Service Container Terminal as part of the Long Beach Mega Terminal Development Plan, and consolidate and redevelop existing Piers G and J to accommodate growing cargo volumes to year 2020.

    The design of this project initially began 30 years ago as a landfill operation for Pier G226. The landfill operation included the placement of hydraulic fill dredged from the harbor. The fill area was contained by a shoreline rock dyke embankment and a soil surcharge was placed over the hydraulic fill to prepare the area for future development.

  • TenCate Mirafi® HP Stabilization of Soft Swamp Subgrades Using Woven Geotextiles US 90 Roadway, Louisiana, USA

    US90 Roadway

    Overview:
    Constructing roads through the extensive swamp areas of South Louisiana, USA is typical of this type of application, and a major challenge for the Louisiana Department of Transportation. Uneven long term differential settlement of road embankments, especially when embankments are constructed using sand fill results in an uneven road level and the typical "roller coaster" ride that is so familiar to drivers.

    Surface pumping of the initial layers of fill installed over soft wet subgrades is a typical consequence when geotextiles are not used. The problem can be typically solved using either a combination of non-woven geotextiles with one or more layers of biaxal geogrid to reinforce the subbase layers, or a single layer of high strength and modulus woven geotextile.

  • TenCate Polyfelt® PGM Airport Runway Repair - Zeltweg Airbase, Austria

    Zeltweg Airbase, Austria

    Overview:
    In June 1990, the runway of Zeltweg Air Base in Austria had to be repaired. The surface consisted of an old concrete pavement which had been overlaid with asphalt several times in the past decades.

    Severe cracks had reflected from the concrete surface through the asphalt overlays. The total area to be repaired was 1700m x 80m = 136,000m2.

  • TenCate Polyfelt® PGM-G Asphalt Reinforcement Pavement Adhesion Performance - Subic Int Airport, Philippines

    Subic Airport, Philp

    Overview:
    Subic International Airport located in Western Luzon was originally constructed as Naval Air Station (NAS) of the US Navy in 1956. The pavement in the runway touchdown zones consisted of cracked concrete pavement. To prevent the cracks reflecting through the new overlay, the consultant specified a reinforced paving fabric to be installed between the old concrete pavement and new overlay.

    The reinforced glass paving fabric consisted of a nonwoven needle punched polypropylene geotextile reinforced with glass fibres. The purpose of the paving fabric was to function as waterproofing, stress absorption and reinforcement layer between the new concrete overlay and the old pavement.

    Both field monitoring and laboratory tests have shown that paving fabric can increase the design life of new pavement overlays, while feasibility studies done by the project consultant showed that a cost savings of more than 28% could be achieved using paving fabric compared to conventional pavement rehabilitation method.

  • TenCate Polyfelt® PGM-G Asphalt Reinforcement Pavement Fabric Pavement Rehabilitation Work - Phuket Int Airport, Thailand

    Phuket Airport, Thailand

    Overview:
    Phuket is one of the most important tourist destination in Thailand. In 2002, the runway of the International Airport with its more than 100,000 passengers per year needed urgent improvement.

    As it was not possible to close the airport during rehabilitation works, the works had to be carried out at night, from 11.00pm until 6.00am. This was a challenge to the paving crew; each night, approximately 1,000m2 of Polyfelt PGM were installed within 2 to 3 hours, followed by the installation of the new wearing course. Works had to be finished at 6.00am latest to allow the first flight schedule begin at 8.30am each morning.

    Along the entire high impact center line of the runway, the old asphalt concrete surface had to be milled to a depth of 10cm before installing Polyfelt PGM-G 50/50, followed by a leveling layer. Finally another layer of Polyfelt PGM-G was applied over the whole width, covered by two layers of asphalt concrete, each 50mm thick.

  • TenCate Polyfelt® PGMG Expressway Rehabilitation Works - North Luzon Expressway, Philippines

    Luzon Expressway, Philp

    Overview:
    The project is located 70km north of Manila. The old pavement was Portland Cement Concrete Pavement (PCCP) which had reached it serviceability design life of 20 years. Visual site inspection showed that the pavement was heavily deteriorated with longitudinal and transverse cracks and spalling joint and concrete scaling in some areas. Due to high traffic volumes and it is main link to Manila, it was not viable to close the highway. The Department of Public Works & Highway decided to use paving fabric to rehabilitate the road instead of conventional "remove and replace method (re-blocking)" to minimize traffic disturbances and construction time.

  • TenCate Polyfelt® PGM-G Pavement Rehabilitation Work - NATO Airport Plovdiv, Bulgaria

    Nato Airport, Bulgaria

    Overview:
    In June 2001, the runway of the NATO Airport Plovdiv in Bulgaria had to be repaired. The old pavement structure consisted of old rigid concrete slabs which were constructed without longitudinal hinge joints. This resulted in warping cracks occurring in both longitudinal and transverse direction.

    Polyfelt technical assistance and experience was sought to provide the most economical solution. After analysis, it was determined to use a combination of Polyfelt PGM-G 50/50 and PGM-G 100/100 for taxiway and runway in order to prevent the propagation of reflective cracks from the old concrete pavement to the new asphalt concrete overlay.

    Polyfelt PGM-G was supplied in rolls of 1m width. Installation was carried out buy using a manual laying machine. In total, 50,000m2 PGM-G 50/50 and 70,000m2 PGM-G 100/100 were used.

    Yangon Airport, Myanmar

    Overview:
    Yangon International Airport in Myanmar was originally constructed by the Calcutta Metropolitan Airports Authority in 1947. The 2,470m runway is 61m wide and comprises asphalt concrete with touchdown zones comprising reinforced concrete in 7.6m x 7.6m panels.

    The upgrading works proposed installation of 125mm of new asphalt concrete, laid in two layers of 75mm and 50mm, over the whole runway, including concrete touchdown zones.

  • TenCate Polyfelt® TS Geotextile Separator on Arabian Seafloor - Jamnagar Gujarat, India

    Jamnagar Gujarat, India

    Overview:
    Jamnagar refinery is a crude oil refinery located at North West of India with production capacity of 661,000 barrels per day. As the expansion to double its production capacity to 1.2 million barrels per day will generate huge volumes of wastewater during the process of crude oil extraction, it was proposed to dispose the treated wastewater through the pipelines laid on the seafloor to avoid contamination of the environment surrounding the refinery. Five 1.4m diameter and two and a half kilometers pipes were laid in a 70.5m wide x 3.5m deep pre-dredged trench on the seafloor.
