There are 12 testing lanes. Each full-scale test lane is 50 by 4 meters (165 by 13 feet), and can be further divided into 4 subsites, for a total of 48 test locations on the facility grounds. A supplemental three cell test pit is available for material testing. The test pit contains a reaction frame for load plate testing.

TEST RESULTS Upon the initial combining of distilled water with the recycled crushed PCC drainable base material, the water pH soon rose to the range of 12.5. Over the first 10 weeks of testing the pH gradually came down to around 11.5.

Dec 01, 2017 Type of aggregate shows great effect on flow table test results of geopolymer mortar. Using crushed limestone resulted in low mortar flow while combined sand shows better flow. On the other hand, geopolymer mortar including natural sand shows better flowability compared to other aggregates. The effect of grading was also verified experimentally.
