TRAFFIC -BOUND SURFACE COURSE
402.01 Description
This work consists of constructing a surface course of hard and durable particles of sand, gravel, mine chats, crushed stone, or disintegrated granite and placing the surface course material on a prepared subgrade.
402.02 Materials
Provide aggregate materials in accordance with Subsection 703.05, “Aggregates for Traffic Bound Surface Course.”
402.03 Equipment — Vacant
402.04 Construction Methods
A.Preparation of Subgrade Complete the subgrade in accordance with Subsection 310.04.A, “Subgrade Method A for Traffic - Bound Surface Course” or Section 202, “Earthwork” before placing surface course material on the subgrade .
B.Shaping and Maintenance Shape and compact as directed by the R esident Engineer if placing material adjacent to the roadway. Correct irregularities, such as holes, ruts, waves, and undulations, with material from the working windrow on the subgrade. Continue shaping the surface material until it is compacted and free of irregularities. Place the surface course material to the elevations shown on the Plans. Remove excess material and stockpile at a location approved by the Resident Engineer.
C.Traffic Control Unless otherwise specified, avoid closing the road to traf fic. Minimize interference with traffic. Maintain warning signs and lights to safeguard against traffic accidents. Place windrows or piles of surface course material on the shoulders and off the traveled roadway at the end of the workday.
402.05 Method of Measurement
For each material quantity of the relevant traffic -bound surface course pay item, the Resident Engineer will deduct the weight of moisture that is in excess of 5 percent of the oven -dry weight.
