Ann: EdenCrete - Vail Pass Colorado Trial Update, page-5

Of course the most important comparison is concrete with Edencrete, versus concrete without Edencrete (not concrete versus ashpalt). For the former comparison it would seem that Edencrete made NO difference. In fact the joints appear WORSE. See these two extracts from page 3 of the report (and note there was a third road section with silca fume which appears to be worse but I haven't copied that here)

Concrete Test Section 1 – Class P Mix, Control
This sample area begins 300 feet east of the beginning of the first concrete test section (MP 184.008) and extends approximately 100 feet east. The sample area contains 32 slabs that are on average 66 inches by 72 inches. Rutting in both wheel paths was measured to be 0.25 to 0.38 inches throughout the sample area. This rutting is due to chain wear and is resulting in the wearing away of the concrete paste, polishing of aggregate, and the popout of some aggregate material from the surface. In general the joints are in good condition with minimal spalling, though the joint sealant has come out of the transverse joints and some joints are beginning to fill with fines. It should be noted that the rutting in this area is trending towards the left of the lane, though most traffic appears to still be running close to the centers of the panels.

Concrete Test Section 2 – Class P Mix with EdenCrete
This sample area starts 200 feet west of the end of the second concrete test section and extends approximately 100 feet east towards the end of the test section. The sample area contains 32 slabs that are on average 66 inches by 72 inches. Rutting in both wheel paths was measured to be 0.25 to 0.38 inches throughout the sample area. This rutting is due to chain wear and is resulting in the wearing away of the concrete paste, polishing of aggregate, and the popout of some aggregate material from the surface. However, the joints are in fair condition with minor spalling at the joints and at corners. The joint sealant has come out of the transverse joints and some joints are beginning to fill with fines. It should also be noted that the rutting in this area is trending towards the left of the lane, though most traffic appears to still be running close to the centers of the panels.
