Steps to oversee the implementation of road projects - an earthworks 1
|
Of the pieces:
1 - check the clean areas of construction (roads) of the waste and grass and trees and any materials that do not need the build process.
2 - The Preview output of the pieces, the soil was suitable for bridge according to specifications Vtstaml in the landfill, although the soil resulting pieces are not valid for the bridge; either to improve their properties and used in reclamation, after improvement, or give permission to the contractor to be transported off-site for the invalidation of the bridge. And testing soil classification according to the specifications.
3 - give permission to the contractor to transfer the output of the hyperbolic or non-potable bridge to off-site according to the form prepared for this purpose (Form No. 6).
4 - When you access to the contour machining is required to verify the validity of the original soil layer base (Sub grade) by conducting the following tests:
- Gradient (analysis Almnkhala).
- Limits Atrberg (liquidity limit - limit plasticity - plasticity coefficient)
- California Bearing Ratio C. B. R.
In the case of validity left to be processed as a class base (Sub grade).
In the case of non-validity either to improve or replace the soil properties of the other valid.
5 - is an experiment, Proctor base material layer to determine the maximum dry density and moisture content, where the optimal placement is to test these values in the density field (see lab manual).
6 - Receive Messahaa base layer (axes + levels).
7 - Verification of the flat surface of the base layer.
8 - Check the rate of compaction and moisture content of the base layer in situ density test field Field density and placement to the maximum dry density by Proctor test on the same material.
* Important Note:
If necessary, the use of explosives in the rock are Alqtaaat coordination with the competent authorities, according to the instructions of that organization, referred to in clause 2/4/6 in the first part.
