What type of material should be used under a stabilized construction entrance?

The use of geotextile fabric under a stabilized construction entrance is essential because it serves as a separation layer that prevents the mixing of subgrade soil with the aggregate placed for the entrance surface. This prevents the aggregate from becoming mudded or compacted down into the soil, which would reduce its effectiveness. The fabric also allows for drainage, ensuring that any water that infiltrates the entrance does not cause erosion or sediment buildup.

Using wood chips, plastic sheeting, or sand may not provide the necessary stability and effectiveness required for a construction entrance. Wood chips can decompose and deteriorate over time, while plastic sheeting could become displaced and not allow for drainage, leading to potential issues with mud and sediment tracking. Sand, while granular, does not offer the structural support or separation necessary for a stable entrance, making geotextile fabric the superior choice for maintaining both functionality and compliance with erosion and sediment control practices.
