Assessing the Adequacy of Glass Fibres in Dense Bituminous Macadam Grade 2

Highways are a principal foundation in the national economy and social welfare, since they give mobility and accessibility to drivers and loads. India is having the second biggest highway organize in the world. A bituminous blend is a blend of coarse aggregate, fine aggregate, rock filler and Binder. The present review expects to create bituminous mix for the Dense Bituminous Macadam Grade-2 utilizing the glass filaments. In this paper, at first VG 30 review binder content has been taken as 4, 4.2, 4.4, 4.6, 4.8 and 5.0 % of the aggregate blend and finds the Optimum Binder Content for typical blend utilizing distinctive volumetric properties of Marshal Mix outline. In order to modify the properties, glass fibres in extent of 0.3%, 0.4% and 0.5% of the total mix are added in mix at OBC. In fibre reinforced bituminous mix the test result show that the Marshall Stability and flows values increased for 0.4% of fibre content in respect to 4.62% optimum binder content. The change of the properties of bituminous mixture shows the constructive outcome of glass fibers.
