What are the general laying methods of Geogrid
Mechanism of glass fiber grid to prevent reflection crackThe above four methods are used to calculate the thickness of asphalt overlay on old cement concrete pavement. In order to prevent the occurrence of reflective cracks, the use of thick asphalt overlay. But relying solely on the increase of the overlay thickness has its drawbacks: on the one hand to increase the overlay thickness by the pavement elevation limit (Ningtong highway overpass bridge clearance in the overlay should meet the requirements of 4.8m); another is a substantial increase in the thickness of overlay will increase the cost of pavement, and under the condition of high temperature in summer the asphalt mixture high-temperature creep prone to rutting, will lose the advantage of strong foundation and thin surface due to the old cement concrete plate base generated, thus thickening asphalt overlay, this approach is not desirable.
