NTL Classification:NTL-HIGHWAY/ROAD TRANSPORTATION-Soils and Geology ; NTL-HIGHWAY/ROAD TRANSPORTATION-Materials ; NTL-HIGHWAY/ROAD TRANSPORTATION-Pavement Management and Performance ;Format:Subject/TRT Terms:Abstract:Shrinkage cracks in cement-stabilized bases/subbase can be alleviated by specifying
the right cement dosage, or by other additives/procedures that suppress crack susceptibility. A field
trial of six 1000 ft test sections to investigate several alternative techniques was initiated and
constructed in August 2000. The following additives/procedures are included for investigation: Control group cement with 5.5% cement additive; design based on a reduced
strength criteria, 5.5% cement precracked while "young", 5.5% cement precut (grooved) every 3m (10 ft), 3.5% cement with 8% fly ash, Ground granulated blast furnace slag (GGBFS) complemented by 2% lime, Three percent lime and 12% fly ash, the current favored stabilization technique of MDOT. This interim report covers the tests and results conducted in three stages: Mixture design, Construction monitoring, Post-construction evaluation.
