Methods of Soil Stabilization and Their Application to the Construction of Airfield Pavements.

Suitability of Flyash-Lime-Phosphogypsum Composite in Road Pavements

“…The 7-day unconfined compressive strength for gravelly and sandy soil is adopted by Association of American State Highway and Transportation Officials (AASHTO) is varying between 2072.9 kPa to 4144.7 kPa. The 7-day unconfined compressive strength of soil-cement mixes to be varying between 1765.8 kPa to 3384.5 kPa as reported by [31]. The unconfined compressive strength of the reference mix at 28 days of curing is 2193.87 kPa which falls in between these two criteria.…”

Research and Its Application to Road Construction.

“…If the points of support were sufficiently numerous and widely spaced, then accuracy of formwork might be of no major consequence, but limitations in overall length of equipment required some degree of compromise between the two. 35. A similar principle is involved in operating the American slip-form paver, which is reputed to give surfaces of excellent riding quality.…”
