Soil Stabilization Field Trial, Interim Report 2
1.2 Scope/Objective of the Study Seeking for materials and methods to alleviate cracking in cement-treated soil, six field sections were constructed in August 17 and 18, 2000 incorporating the following material combinations or methods each in a separate but contiguous test section of 305m (1000 feet) long: cement, precracked cement layer, precut cement layer, cement-fly ash, lime-ground granulated blast furnace slag (GGBFS), and lime-fly ash (LFA). First interim report covering the first phase of investigation/monitoring during the 28-day period was submitted in April 21, 2001. Two layers of asphalt concrete 11cm (4.5 inches) base, 6cm (2.25 inches) polymer modified binder were placed over the stabilized layer beginning September 21, 2000, followed by the second field monitoring on November 13, 2001. Field tests include deflection tests employing Falling Weight Deflectometer (FWD), retrieval of 10-cm (4-inch) cores for compression tests, and a manual crack survey. The results are presented in this report along with a discussion as to possible changes (strength- and stiffness-gain, and crack reflection) over a fourteen-month period, since September 15, 2001 when the last monitoring was completed.
