Design and Evaluation of Foamed Asphalt Base Materials

release date: Jan 01, 2013
Design and Evaluation of Foamed Asphalt Base Materials
Foamed asphalt stabilized base (FASB) combines reclaimed asphalt pavement (RAP), recycled concrete (RC), and/or graded aggregate base (GAB) with a foamed asphalt binder to produce a partially stabilized base material. The objectives of this study are to determine for Maryland conditions: (1) FASB mix design procedures; (2) typical engineering and structural design properties; (3) guidelines for FASB production and placement; and (4) best practices for construction quality assurance. The study consisted of three major components: (1) laboratory evaluation of FASB mix design procedures; (2) field evaluation of in-place FASB stiffness, and especially the increase in this stiffness with time due to curing; and (3) direct laboratory measurement of the performance related properties of FASB, specifically dynamic modulus and permanent deformation resistance.

Superpave

Superpave
"This guide provides an overview of the Superpave mix design methodology and information, including a set of tutorials, for using the Superpave Software Version 1.0 to perform mix designs. The current Version 1.0 of the Superpave software includes only the Superpave volumetric mix design method. Future versions of the Superpave software will also incorporate the accelerated mix performance analysis procedures"--Technical report documentation p.

Round River

Round River
To those who know the charm of Aldo Leopold''s writing in A Sand County Almanac, this collection from his journals and essays will be a new delight. The journal entries included here were written in camp during his many field trips--hunting, fishing, and exploring--and they indicate the source of ideas on land ethics found in his longer essays. They reflect as well two long canoe trips in Canada and a sojourn in Mexico, where Leopold hunted deer with bow and arrow. The essays presented here are culled from the more contemplative notes which were still in manuscript form at the time of Leopold''s death in 1948, fighting a brush fire on a neighbor''s farm. Round River has been edited by Leopold''s son, Luna, a geologist well-known in the field of conservation. It is also charmingly illustrated with line drawings by Charles W. Schwartz. All admirers of Leopold''s work--indeed, all lovers of nature--will find this book richly rewarding.
