Temporal And Spatial Variability In Base Materials Treated With Asphalt Emulsion, Tyler James Quick
Temporal And Spatial Variability In Base Materials Treated With Asphalt Emulsion, Tyler James Quick
Theses and Dissertations
The first objective of this research was to investigate temporal trends in the mechanical properties of base materials stabilized with asphalt emulsion and to assess the rate at which emulsion-treated base (ETB) design properties are achieved. The second objective of this research was to identify construction and environmental factors most correlated to specific mechanical properties of ETB layers and to determine which construction factors exhibit the greatest variability. Additional statistical analysis was performed to determine if significant differences existed between different test sections on a given project. In this research, three experimental sections were established along a pavement reconstruction project …
Strength And Deformation Characteristics Of A Cement-Treated Reclaimed Pavement With A Chip Seal, Bryan T. Wilson
Strength And Deformation Characteristics Of A Cement-Treated Reclaimed Pavement With A Chip Seal, Bryan T. Wilson
Theses and Dissertations
The objective of this research was to analyze the strength and deformation characteristics of a cement-treated base (CTB) constructed using full-depth reclamation, microcracked, and then surfaced with a single chip seal. In this field study, strength characteristics of the CTB layer were determined at the time of construction, and then both strength and deformation characteristics were evaluated after 9 months of low-volume, heavy truck traffic. After 9 months, observed distresses included transverse cracking, rutting, and chip seal joint failure. The loss of the chip seal was caused by poor chip seal construction practices and not a deficiency in the CTB …
