Investigate On Bituminous Mixers With Different Filler Materals

Abstract

Fillers Play An Important Role On Engineering Properties Of The Bituminous Paving Mixes. Conventionally, Cement, Lime And Stone Dust Are Used As Fillers. In This Study, An Attempt Has Been Made To Assess The Effects Of Different Types Of Fillers (e.g. Non-conventional And Conventional) On The Marshall Properties Of Bituminous Paving Mixes. For This Purpose, Non-conventional Fillers Such As Groundnut Shells And Silica Fume And Conventional Fillers Such As Cement And Stone Dust Were Used. All Of These Materials Were Tested According To The Standard Test Procedure Of AASHTO. Test Specimens Were Prepared By Using Different Types Of Filler Having Different Amount In The Mix Of 5% To 7.5%. The Marshall Properties Obtained For Both Types Of Fillers Reveal That, Nut Shells And Silica Fume Specimens Have Been Found To Exhibit Higher Stability Value Compared To Cement And Stone Dust Filler Specimens. In Addition, Mixers Containing Nut Shells And Silica Fume As Filler Showed Maximum Stability At 6.5 % Bitumen Content And The Percentage Of Air Voids Were Found To Be Decreased With The Increase Of Bitumen Content. This Do Research Has Influence Of Conventional And Inexpensive Fillers Such As Walnut Shells And Silica Fumes In Bituminous Concrete Flooring. As A Result Of This Project It Has Been Found That Bituminous Mixtures Containing These Unconventional Loads Produce Satisfactory Properties
