Annex 5: Activity Standards for Local Gravel Road Maintenance 554 ACTIVITY NO. 63X: RESURFACING UNPAVED SHOULDERS I. Description of Activity Use this activity for resurfacing of long (over 50 meters but not exceeding 200 shoulder meters) continuous sections of unpaved shoulders by placing aggregates using laborintensive methods when grader maneuvrability is impaired. II. Purpose To replenish unpaved shoulders that support the pavement, act as safety lanes and drain well. III. Schedule of Application Schedule after approval is received. Do not schedule if base, subbase, or subgrade failures exist. Clean ditches and reshape shoulder prior to scheduling. IV. Construction Method 1. Place safety devices. 2. Spread and shape new aggregate. 3. Compact to thickness of at least 5 centimeters. 4. Check work for cross section, proifle and drainage. 5. Rework if needed. 6. Remove safety devices. V. Daily Production Rate 20 to 30 shoulder meters resurfaced VI. Method of Measurement The quantity of aggregate surface to be paid, shall be the number of centerline kilometers of road aggregates which have been placed, graded, compacted and accepted by the Engineer.
