Abstract :

Abstract -The main function and objectives of the Highway Research division are to study modern trends in design and construction of roads, modify techniques if necessary to suit local conditions and carry out field and laboratory experiments and to provide suitable specifications with special reference to the nature of the locally available material; to assess strength and other properties of construction materials, in particular to investigate the properties of local soil and locally available inferior aggregate with a view to evolve cheap type of rural roads and to study characteristics of various binders like bitumen, tar etc. and their rational use in road construction with locally available aggregates; to study trends of traffic and suggest solutions to problems in view of present trends of increasing speed of traffic; to tackle the problem of road safety in relation to the geometric of highway and psychology of road users (making roads safe for all types of traffic); to carryout research connected with standards and specifications for road building plant and machinery and also to design instruments for road test; to assist the Public Works Divisions in the state, in the solution of important highway problems; to carryout basic research on all aspects of road and traffic engineering. Accordingly this problem was referred by the Executive Engineer, Public Works Division, Nandurbar for field and laboratory investigation and inspection of road length of Ankleshwar Burhanpur Road (SH- 4) having chainage 129/00 to 149/300 and bye pass 0/500 to 4/600. For this, inspection of the site, field investigation, field tests, field samples, testing of samples is done in divisional laboratory of MERI Nashik, collecting field data interpretation of field and laboratory investigations and suggesting the remedial measures are completed. The various causes of failures from investigations are : (1) Failure due to an inadequate crust thickness of existing road pavement. (2) Failure due to weak subgrade i. e. low bearing capacity of soil. (3) Failure due to saturation of subgrade due to under seepage of water and failure due to inadequate road side drainage provision. Crust required for structural failure length is works out to 930 mm while Crust required for surface failure length is works out to 210 mm. Road side gutters should be provided both side, properly sloped to the cross drainage structure.
