Book Description
The Illinois Department of Transportation (IDOT) spends two million dollars annually on reflective crack control treatments; however, their cost-effectiveness has never before been reliably determined. The study evaluated the cost-effectiveness of IDOT reflective crack control system "A", which consists of a non-woven, polypropylene paving fabric, placed either in strips longitudinally over lane-widening joints or over the entire pavement ("area" treatment). Performance of 52 projects across Illinois was assessed through crack mapping and from distress and serviceability data in IDOT's Condition Rating Survey (CRS) database. Comparisons of measured reflective cracking in treated and control sections revealed that system "A" retards longitudinal reflective widening crack development, but does not significantly retard transverse reflective cracking. However, both strip and area applications of these fabric treatments appeared to improve overall pavement serviceability, and were estimated to increase rehabilitation life spans by 1.1 and 3.6 years, respectively. Life-cycle cost analyses (LCCA) found strip and area reflective crack control treatments to be marginally cost effective, where a 4.5% reduction in life-cycle costs was estimated, for medium-sized projects [between 1 and 6 mi (1.6 and 9.7 km) of two-lane road]. Small projects [under 1 mi (1.6 km) of two-lane road] showed a breakeven level of cost-effectiveness, while large projects [over 6 mi (9.7 km) of two-lane road] showed a 6.2% savings in life-cycle costs. Permeability testing of field cores taken over transverse joints showed that waterproofing benefits can exist after reflective crack appearance, which explains why serviceability was improved with area treatment even though crack development was not retarded. Guidelines for establishing and monitoring future experimental sections were also developed.

Book Description
Internationally, much attention is given to causes, prevention, and rehabilitation of cracking in concrete, flexible, and composite pavements. The Sixth RILEMInternational Conference on Cracking in Pavements (Chicago, June 16-18, 2008) provided a forum for discussion of recent developments and research results.This book is a collection of papers fr

Book Description
Geosynthetic materials have entered the mainstream in the professional arena and are no longer considered new construction material. Professionals need to keep up with the nuances of how geosynthetics work. Emphasizes design by function; overviews all types of geosynthetics, with stand-alone units on particular materials. Uses S.I. units for all problems and examples. Expands coverage of containers and tubes in the geotextile chapter. Discusses walls and slope design, including seismic analysis, in the geogrid chapter. Treats wet landfills, agricultural waste, waste stability, and dam waterproofing in the geomembrane chapter. Discusses new products and related performances in the geosynthetic clay liner chapter. Discusses new products and related behavior, including fiber reinforcement and wall drainage, in the geocomposite chapter. Adds a completely new chapter on geofoam. A useful reference for transportation, geotechnical, environmental, and hydraulics professionals and engineers.
