g. The cost effectiveness in which it can be done (50% and more less than existing practices);
h. Compliance under 2010 NSRWA/SROH (UK new roads and street works act) coring specifications.
i. HAPAS (UK Highway Authorities Product Approval) certified.
j. Surrey test certificates: – wheel tracker test
– maximum density test
– skid resistance test
– air void test
4. Do you currently have product(s) certified by Agrèment SA? Y/N No
5. Would you support a process whereby cold asphalt for road repairs should be (ASA) accredited for use in SA? Y/N Yes
6. Please indicate your interest in the three categories of application for cold mix asphalt: ✓
Emergency repair Short term — 1 year life | Durable repair Medium term — ≥5 year life | “Permanent” application Long term — ≥ 10 year life |
7. Have your products been subjected to a HSE assessment to limit exposure to health risks by applicators of the product, and damage to the environment? Y/N Yes
8. Do you have an accessible, formal quality plan for: Manufacture of the asphalt mix? Y/N Yes Application of the product? Y/N Yes
