Use of Geocells in Pavement Design
| 项目名称： | Use of Geocells in Pavement Design |
| 摘要： | In recent years, a new construction technology known as "Geocells" has been developed which increases the bearing capacity of supporting layers with none to minimal increase in cost of construction. However, the benefits (performance and cost) from using geocells in pavement design, particularly in locations where good quality base material is not readily available, are not well understood or documented. The Performing Agency shall determine and document the benefits that derive from the use of the newer generation of geocells in pavement design/construction especially in terms of reducing base layer thicknesses even though low quality base material is being used. The Performing Agency shall focus on evaluating feasibility of using lower/marginal quality base and/or sub-base material in the pavements constructed with geocell systems, which has become essential due to unavailability of good quality base material in many regions of Texas. In this project, the research team shall (1) characterize the mechanisms for improved support, (2) quantify the type of comparatively low quality material that can be used as in-fill of geocells, and (3) quantify the comparatively smaller thickness that could be used in bases or sub-bases when incorporating the use of geocells in pavement design. |
