Suggested levels of inspection for slope protection activities are: Ensure the contractor is actively performing quality control on placing slope protection and slope paving throughout the operations. 8 0 obj The finish surface must be roughened by brushing to expose rocks. Slope Protection consists of rock, concrete, or concreted rock or slope paving ROCK SLOPE PROTECTION ROCK SHOULD DEMONSTRATE Stability: Angular shapes may be used on any planed slope Durability: Resist degradation and have a durability of 52 minimum (Caltrans) Consistency: Product is the same load after load. 0000008354 00000 n Polypropylene is stable within a pH range of 2 to 13. When exposed aggregate slope paving is specified, ensure any concrete set retarders are used in accordance with manufacturer instructions. <>stream Testing must follow the frequencies shown in Section 6-1, Sample Types and Frequencies, of this manual. endobj For RSP Classes I thru VIII, use Class 8 RSP-fabric which has lower weight per unit area and it also has lower toughness (tensile x elongation, both at break) than Class 10 RSP-fabric. The method for placing rock will either be Method A or Method B, whichever the contract designates, as discussed under Section 4-7203A, Rock Slope Protection, earlier in this section. Decide whether an adequate number has been provided for the particular installation. Whether you're speeding down a slope or cycling uphill, the F5 can be worn in a number of ways to fit your training and needs.
