With regard to the Sand Patch test results provided by Breedon, answers appreciated to the following questions (which I have numbered consecutively from my previous submission) also under a FOI/ Environmental Information (Scotland) Regulations 2004 (EIRs) request:
12. As 60% of the Determination of Texture Depth tests were not carried out due to the weather (Rain), how was the road assessed as being safe to be driven on?
13. As the Sand Patch method requires the surface being measured to be dry, please advise the following:
- How could the Sand Patch test not taken Northbound (Ref 7033/A) due to Rain be taken on the same section of road Southbound (Ref 7032/A) on the same day of 8 Sep 2017?
- How could the Sand Patch tests not taken Southbound (Ref 7037/C & 7037/D) due to Rain be taken on the same section of the road Northbound (Ref 7036/C & 7036/D) on the same day of 12 Sep 2017?
- How could the Sand Patch test not taken Northbound (Ref 7038/A) due to Rain be taken on the same section of the road Southbound (Ref 7039/A) on the same day of 13 Sep 2017?
14. I note that the texture depth readings, where recorded, range from 1.1mm to 1.3mm. What is the minimum and/or maximum texture depth tolerance allowable?
15. If the readings had been found to be out with this allowable range, what would be the resulting response?
16. Is there a drawing available which identifies the sections of road against the chainage used to reference the Sand Patch data results?
17. Which side of the road is Northbound and Southbound?
18. Should the Location Reference be noted as Eastbound or Westbound for this section of road instead?
19. What checks were carried out to ensure that there was no conflict of interest between the company carrying out the surfacing work and the one carrying out the texture depth analysis?
20. Was any independent analysis carried out to check the results provided?
