1. Project Title:

   Correlation between Engineering Properties of In-situ Subgrade Materials in Response Study of Flexible Pavements.

   Project Summary:

   California Bearing Ratio (CBR) test result is one of the important parameter used effectively for assessment the strength parameter of soil. But in practice, only limited number of such tests could be performed for evaluating these engineering properties because of high cost and time required for testing. As a result, it is difficult to reveal detailed variation in the strength over the length of roads to enable rational, economic and also safe construction. In such cases if the estimation of the CBR could be developed on the basis of some tests which are quick to perform, less time consuming and cheap, then the process will help the designers and constructors enormously. In this view, a relationship between the compaction characteristics and the CBR of different groups of soils like CL, CI, CH, ML-OL, MH-OH, CL-ML and MI-OI for prediction and quality control purposes.

2. Project Title:

   Utilization of Alternative Materials in the Construction Subgrade and Subbase Layer of Flexible Pavements

   Project Summary:

   The activities in the present research work programme focus on specific sectors within the areas of subgrade and subbase construction of flexible pavements. Due to rapid and wide spread revolution occurred in the field of road network development program, huge quantity of conventional materials becomes needed to meet up that situation. However scarcity of those materials is a common and great problem. Further it has been a great concern to use the industrial wastes, which are being produced in large quantities due to rapid industrialization, creates not only the accumulation hazards but also the environmental pollution. Many industries such as power plants, distilleries, paper mills, and others, were spending a lot of their resources for removing their waste material produced as by product. In order to implement the technically and-economically feasible options successfully there is a need to develop user-friendly appropriate technological solutions which reduces the pollution levels, health hazards, and globally conserving the environment. Hence utilization of such waste materials in huge quantity by confining them appropriately within the different pavement layers with or without addition of geo-textile/ geo-membrane undoubtedly reduces the pollution problems and also reduces the consumption of conventional materials.
