Frictional Resistance Of Aggregates For Hot-Mix Asphalt Pavements, Joan Patricia O'Brien, John E. Haddock
Frictional Resistance Of Aggregates For Hot-Mix Asphalt Pavements, Joan Patricia O'Brien, John E. Haddock
JTRP Technical Reports
In 1997 the Indiana Department of Transportation adopted the Superpave mixture design method and attendant specifications for hot-mix asphalt pavements. Prior to Superpave, the Indiana Department of Transportation aggregate frictional requirements were based on average daily traffic volumes and were divided into low, medium, and high volume categories. With the implementation of Superpave in Indiana, aggregate frictional requirements were reassigned to categories based on equivalent single axle load values. The purpose of the research is to determine whether average daily traffic or equivalent single axle load has a greater effect on the frictional resistance of a hot-mix asphalt pavement, to …
An Evaluation Of The Strategic Highway Research Project Packing Handbook, Kenneth P. Cox, Charles F. Scholer, Menashi D. Cohen
An Evaluation Of The Strategic Highway Research Project Packing Handbook, Kenneth P. Cox, Charles F. Scholer, Menashi D. Cohen
JTRP Technical Reports
The objective of this research is to evaluate the use of the November 8, 1991 SHRP C-206 report entitled, “Packing Handbook – A Guide to the Optimal Gradation of Concrete Aggregates”. The purpose of the Packing Handbook is to determine the optimal combination of fine and coarse aggregates for concrete from available aggregate sources. Through the use of tables provided in the Packing Handbook, and given sources with known aggregate gradations and void contents, the relative proportion of each aggregate (coarse and fine) is obtained. Concretes made using the Packing Handbook recommendations of aggregate proportioning were compared to concretes used …
Synthesis Study On Use Of Concrete Recycled From Pavement And Building Rubble In The Indiana Highway System, Thomas T. Burke, Menashi D. Cohen, Charles F. Scholer
Synthesis Study On Use Of Concrete Recycled From Pavement And Building Rubble In The Indiana Highway System, Thomas T. Burke, Menashi D. Cohen, Charles F. Scholer
JTRP Technical Reports
The demolition of buildings and highway pavements in the State of Indiana generates a considerable amount of waste materials. The disposal of these materials causes strain on the existing landfills which are rapidly approaching their full capacity. This study is a synthesis of the information on the use of concrete recycled from pavements and building rubble for use in the Indiana highway system. Test results have shown that recycled pavement concrete made chiefly from broken-up and crushed old concrete aggregate is as good as concrete made from virgin aggregate, and sometimes better. The aggregates made from recycled concrete can be …
