Needle Punch,Multifilament Hdpe Asphalt Over Lay Geo Textile , For Roads,

We are offering a Aslt Over Lay Geo Textile. When used to fulfill the filtration process in roads, Geotextiles have significant advantages. The removal of water is important to the success of many civil engineering problems. In transportation applications, if the base course does not drain rapidly enough, stress form the traffic loading is transferred to the subgrade with little or no reduction, resulting in accelerated road failure. The removal of water must be performed in a controlled fashion.

Otherwise, severe erosion, piping, settlement of soils may result in undermining adjacent structures. To accomplish this task, the drainage system should fulfill two criteria: maintenance if the permeability (by providing relatively unimpeded flow of water), and filtration of the base soil (by preventing the migration of the soil fines into the drain). These criteria can be met by using several layers of specially graded aggregates. This often proves to be an extremely expensive requirement to meet. The same result can be achieved at a fraction of the cost by using selected Geotextiles, which act as filters around the aggregate drainage system. The introduction of Geotextile ined systems has enhanced the technical properties and economic application of blanket and trench drains under and adjacent to pavement structures. The exnt filtration and separation characteristics associated with Geotextiles permit the use of a single layer of open graded aggregate base or trench aggregate enveloped in a Geotextile. Thus, when Geosynthetics are used within pavement structures for drainage and moisture control, they enhance the pavement structure and lengthen its performance by reducing the influence moisture has on the pavement materials.
