Feasibility of Stabilized Zn and Pb Contaminated Soils as Roadway Subgrade Materials

Table 3

Zn and Pb concentrations and curing times for various tests and analyses of spiked soils.

Test program	Zn or/and Pb concentration (%)	Binder content (%)	Curing time (d)
ANC	Zn0Pb0, Zn1.5, Zn1.5Pb2, and Pb2	6	28
MIP	Zn0Pb0, Zn0.5, Zn1, Zn1.5, Zn1.5Pb2, and Pb2	6	28
WSD	Zn0Pb0, Zn1.5, Zn1.5Pb2, and Pb2	4, 6	6, 27
RMT	Zn0Pb0and Zn1.5Pb2	6	28

ANC = acid neutralization capacity; MIP = mercury intrusion porosimetry test; WSD = water-soaking durability test; RMT = resilient modulus test. Untreated clean soil.
