The concept of rational pavement design for design of bituminous pavement was conceived during the 1960s (Dorman 1962, Monismith et al. 1961). Its upgraded version is known as Mechanistic-Empirical (M-E) pavement design, and is at present popularly being used for design of bituminous pavements in various countries. A number of pavement design guidelines (Austroads 2004, French 1997, IRC:37 2001...

The cold in-place recycling (CIPR) is a process where the existing bituminous pavement is recycled without application of heat. In CIPR process the scarified material from the existing pavement is crushed to the required gradation and binder in cold form (emulsion or cutback or foamed bitumen) is added. Externally acquired Reclaimed Bituminous Pavement (RBP) or fresh aggregates are also added d...

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...

In certain sections of the state of Indiana sources of recognized ag­ gregates for use in bituminous construction are very few, and the trans­ portation of aggregates to the job site from remote locations becomes necessary. Often the distance over which the aggregate must be moved is considerable, and the importation involves the expenditure of a size­ able sum of money, which it would be desir...

modified bituminous materials can bring real benefits to highway maintenance/construction, in terms of better and longer lasting roads, and savings in total road life castings. this paper present the effect of there novel modifier as precipitated calcium carbonate (pcc) and two type of nanoclay on rheological properties of bitumen binder. various blends of modifier and bitumen were selected and...

Most road surfaces globally are constructed using bituminous materials. The construction of new roads and the maintenance existing ones demand a huge amount virgin natural aggregates. Depletion resources that takes place during has an impact on cost also environment. Hence, there is need to reduce aggregate use for pavement construction. This can be achieved by utilizing sustainable materials s...
