Evaluation of Reclaimed Hydrated Fly Ash as an Aggregate for Sustainable Roadway Base Material

Table 3

In situ resilient modulus and modulus of the subgrade reaction for HFA C-stone.

Test item	Cure # days	Geogrid	Modulus of the subgrade reaction (kPa mm)	Resilient modulus (MPa)	Permanent deflection-cyclic plate load test (mm)	Number of 690 kPa stress cycles
1	0.5	No	39	42	11	100
2	7	Yes	237	122	2	100
3	28	No	—	83	3	40

Total deflection minus seating deflection (cycle = 1). Not tested due to weather delay.
