The strength and serviceability requirements of bituminous mixture such as Stability, Flow, Voids in Total mix (VTM), Voids Filled with Bitumen and (VFB) highly depend on the physical properties of aggregates. This study conducted by observing the effect of flakiness & elongated index by adding different …show more content…
OBJECTIVE OF STUDY To study the effect of different proportions of flaky & elongated particles (0 %, 10%, 20%, 30%, 40%, and 50%) taking 5.2% as constant bitumen content of CRMB. • To study the basic properties of CRMB. • To study the properties of stability, flow by varying the percentages of elongated aggregates using Marshall stability test • To study the bulk density and volumetric properties (VTM, VFB, VMA) 0f Marshall Specimen’s. III. EXPERIMENTAL INVESTIGATIONS Basically the materials that are used in this study include aggregate components such as stone dust and flaky & elongated aggregates. Second important item is Base bitumen. The most important tests which are carried out along this thesis are sieve analysis, flakiness & elongation index test and Mix design by using Marshall Mix design method.
