Recycling Bituminous Pavements

This paper is a summary report on a research project entitled “An Investigation of Recycling Bituminous Pavements,” an HPR Research Project conducted by the JHRP staff at Purdue University. The research was performed by James L. McKinney, Graduate Instructor in Re­ search, under the direction of Professors Donn E. Hancher and Leonard E. Wood. Copies of the final report are available through the...

Recycling of Bituminous Pavements

IN T R O D U C T IO N The major material utilized in the construction of the roads, streets and highways of this country is asphalt. Of the nation’s 3.84 million miles of roads, 1.86 million are paved, hard-surfaced structures. 1.74 million or 94% of these paved roads are constructed of asphalt (Fig. 1). Likewise, within the state of Indiana, 83% or about 9300 miles of the 11,200 miles under th...

Behavior of Flexible Pavements on Expansive Soils

This investigation discusses the findings on analysis results of a pavement structure constructed on a relatively expansive material consisting mainly of brown clayey silt in Tebessa, Algeria. Cores were brought to the laboratory from a piece of roadwork. Remolded samples were taken from subgrade of a deteriorated road. The soils were generally found to be of medium plasticity and of a medium t...
