What are the function of layers in a flexible pavement?
· The Capping Layer. Capping materials are typically secondary aggregates or recycled demolition materials. They may also be lime or cement stabilised soils. The thickness required by the capping or subbase layer may be reduced by the inclusion of a stabilisation geogrids, such as the Tensar geogrid at the base. The aperture size should be ......

How Recycled Plastic Can Be Used in the Construction Industry
Many of these recycled plastic products are made from recycled plastic, while others are known as "wood polymer composites" and use a blend of recycled plastic and recycled wood. The materials created can be shaped as needed and are used in ....
Recycled Aggregates from Inert Waste
aggregate in Scotland is either capping material ( 6F4 and 6F5) or subbase ( Type 1). Some production sites can produce aggregates for concrete, such as washed sand, but this is less widespread. The WRAP specifier tool has details of the different aggregate types....
Capping Layer Use Of Recycled Concrete
Capping Layer Use Of Recycled Concrete. May 30, 2018 On weak subgrades, it is common practice to use a capping layer between subgrade and subbase layers. This reduces the thickness of subbase and provides a suitably firm surface ....

· This Green Road included base layers directly under asphalt, capping layers and bedding material. Over 200,000 tonnes of recycled concrete materials were supplied to the project and resulted in a saving of 17,000 tonnes of material, or 412 less truck loads, and a carbon saving of approximately 1,265 tonnes. Peninsula Link...
Capping Layer
Capping Layer A capping layer is installed to reduce the effect of a weak subgrade on the structural performance of a ground supported concrete floor. Technical Information A capping layer is laid over a poor quality subgrade, ensuring that it will provide stiffer resistance to the loads from the structure above....
Capping Layer
A capping layer helps to create a construction platform where the subgrade is not viable. It is granular product from a crushed rock quarry, and often incorporates recycled materials. Capping layer materials help to reduce costs and to protect the subgrade from rainfall and weathering. In road construction the disruption caused by wet weather ......
Capping Layer Use Of Recycled Concrete
Recycled SubBases SoilsStone. Soils and Stone can supply two different graded granular fills: 6F4 and 6F5. These materials typically contain crushed concrete, recycled asphalt and possibly crushed brick. 6F1/6F4 (formerly 6F1 Recycled) is a finer capping layer that is used in the same way as 6F5 but with a finer grading. 6F4 is generally to dust....
Road Pavement Design Guide
The design of a scheme should enable the maximum use to be made of the material available on the site for capping layer, subbase or roadbase by using a permitted binder. In addition, the use of construction materials from sources that maximise the amount of recycled materials is ....
