RECOVERY - XUMU041146B - Maintain Slopes, Lower Honda Ridge Road

This project is intended for repairing landslides at the Lower Honda Ridge Road at VAFB, CA. Work will involve removing all the existing asphalt in two areas. Station 52 + 30 to
Station 54 + 00 (Area 1) will be over excavated at a 5-foot depth, with a 2-foot keyway on each side of the road. Station 55 + 45 to Station 62 + 00 (Area 2) will be over excavated section (Station 56 + 75 to Station 60 + 50) and will consist of over excavating 10 feet in depth, with a 5-foot keyway on the low side of the road. On the high side of the road the existing cut slope will be cut back approximately 24 to 30 feet to move the road away from the vertical edge of the pavement. This will create an approximately new 2:1 cut slope and move the road over 12 feet to the high side. This will expand the shoulders of the road. All standards and specifications are in compliance with the soils report provided. Due to needed drainage control over side drains will be removed and replaced with new material. Energy dissipater will be installed at the end of the downstream side of the culvert. Road widening, earth work, asphalt construction will induce: Clear & grub; Excavate unsuitable material; Over excavate unstable sub-structure; Grind out road; Compacted fill; Stabilized aggregated base; Install new over side drains/asphalt concrete aprons; Remove & replace 18-inch diameter culverts; Apply 3-inch minimum asphalt pavement; Apply striping to new pavement to original configuration; facility to be reused as a recycled road base or used for road base on site.
