STD. & SPEC. 3.02 TEMPORARY STONE CONSTRUCTION ENTRANCE Practice Description A stabilized stone pad with a filter fabric underliner located at points of vehicular ingress and egress on a construction site, used to reduce the amount of mud transported onto paved public roads by motor vehicles or runoff. Conditions Where Practice Applies Wherever traffic will be leaving a construction site and moves directly onto a public road or other paved area. Construction Specifications 1. Aggregate Size: VDOT #1 Coarse Aggregate (2- to 3- inch stone) should be used. 2. Entrance Dimensions: The aggregate layer must be at least 6 inches thick; a minimum three inches of aggregate should be placed in a cut section to give the entrance added stability and to help secure filter cloth separator. It must extend the full width of the vehicular ingress and egress area and have a minimum 12-foot width. The length of the entrance must be at least 70 feet (see Plate 3.02-1). 3. Washing: If conditions on the site are such that the majority of the mud is not removed by the vehicles traveling over the stone, then the tires of the vehicles must be washed before entering the public road. Wash water must be carried away from the entrance to an approved settling area to remove sediment. All sediment shall be prevented from entering storm drains, ditches, or watercourses. A wash rack may also be used to make washing more convenient and effective (see Plate 3.02-1). 4. Location: The entrance should be located to provide for maximum utilization by all construction vehicles. 5. The area of the entrance must be excavated a minimum of 3 inches and must be cleared of all vegetation, roots, and other objectionable material. The filter fabric underliner will then be placed the full width and length of the entrance. 6. Following the installation of the filter cloth, the stone shall be placed to the specified dimensions. If wash racks are used, they should be installed according to manufacturer's specifications. Any drainage facilities required because of washing should be constructed according to specifications. Conveyance of surface water under entrance, through culverts, shall be provided as required. If such conveyance is impossible, the construction of a "mountable" berm with 5:1 slopes will be permitted. Applicant Packet 23 June 2001 CE
The filter cloth utilized shall be a woven or nonwoven fabric consisting only of continuous chain polymeric filaments or yarns of polyester. The fabric shall be inert to commonly encountered chemicals and hydrocarbons, be mildew and rot resistant. Maintenance The entrance shall be maintained in a condition that will prevent tracking or flow of mud onto public rightsof-way. This may require periodic top dressing with additional stone or the washing and reworking of existing stone as conditions demand and repair and/or cleanout of any structures used to trap sediment. All materials spilled, dropped, washed, or tracked from vehicles onto roadways or into storm drains must be removed immediately. The use of water trucks to remove materials dropped, washed, or tracked onto roadways will not be permitted under any circumstances. Applicant Packet 24 June 2001
