NEW PROJECTS
Design Options based on Performance Analysis of Rural Roads in Uttaranchal

Date of Start:July 2003
(i) Department of Science and Technology, New Delhi (S)
(ii) Centre of Transportation Engineering, Indian Institute of Technology, Roorkee (R, I)

Scope and objectives

(i) To classify the rural road sections constructed under different schemes and PMGSY in Uttaranchal on the basis of different      condition of roads, terrain, traffic, rainfall, soil subgrade and pavement composition.
(ii) To assess the rural road condition of selected test sections through structural and functional evaluation.
(iii) Studies of each section will be carried out to assess the type and thickness of the different pavement layers by taking      cores.
(iv) To develop the performance models for rural roads.

Methodology
(i) The studies on identified test sections will be carried out three times in a year, i.e., Pre – Monsoon, Post – Monsoon and      during Winter Season.
(ii) The test sections will be categorized according to traffic and rainfall (low, medium & high) as well as type of soil, terrain      (plain/hilly) and pavement composition.
(iii) The structural and functional evaluation of the identified test sections will be carried out.
(iv) Based on the studies performance models for rural roads will be developed.

Conclusions

The field studies are in progress and the process of categorization of test sections is being finalised.

Significance / Utilisation Potential

(i) Uttaranchal State is a typical example of plain and hilly areas and extreme climatic condition with large variation in soil     subgrade, terrain. Climate (temperature / rainfall), traffic and pavement composition.
(ii) The performance model of rural roads aimed to be developed will relate to material / design parameter, traffic, climate, and      distress factors. The performance model will be useful for pavement maintenance schedules and improvement in      maintenance strategies. It is expected that the above performance model can be used for other hilly states in the      Himalayan Region of the country.

Limitations

The performance of rural roads is a typical phenomenon involving lot many factors. To relate the performance with the design and material properties, a vast database is required. So a database for rural roads should be maintained which will help in calibrating the performance models according to the site conditions.
