• SYSTEM INVENTORY p Master Inventory The appendix contains.the various tables prepared for this study. Table 1 - System Inventory, contains 336 roadway segments generally on a block by block basis. The segments were assigned a segment number starting in the southwest corner and proceeding northerly and easterly. Table 1 lists the following items for each roadway segment 1. length (in feet) 2. width (in feet) 3. surface area (in square yardsl - 4. year constructed, if know,i 5. year of last major mainten�e9Teeuch andas seal percent`oat if known 6. surface distress by type 7. functional classification is the measure used to d?termine the needed level of The surface distress - repair work to the street system. The pavement surface condition survey s ystsm was developed in 1979 by Texas A G M University and was bated upon research supported by the National Science Foundation. -'fhe following is a - type of surface and or structural distress criteria description Of the used is the Street Maintenace Study. 1. RutL•i T)'An obvious depression in the pavement parallel to the side of the street. - - - Factors in determining severity: Slight -depression measures less than 1/2-inch does. p��,,f Moderate -depression measures approximately 1/2 to 1-inch deb"+ but not deep enough to prevent easy steering of a vehicle - Severe -depression is deep enough to prevent easy steering of a vehicle. 2. Raver --A breaking of the surface with visibly loose pieces of aggregate. Factors in determining severity: - Slight -a few pieces of aggregate are visibly dislodged from the pavement and are loosely sitting above the street's surface. Moderate -pieces of loose aggregate are present enough to cover wide area* of the street's surface. Severe -pieces of loose aggregate are so prevalent that they cause the street's surface to be rough enough to be noticeable when driving ❑ vehicle over the street. Flushing (F)•j%sphalt covers tho aggregate. Factors in determining severity: Slight -asphalt is barely noticeable in its covering of the aggregate. Moderate -asphalt is covering large areas of the aggregate. Severe -.asphalt is toally covering the aggregate.
