| 摘要： | Bituminous concrete is one among the most widely used construction materials as top layer on roads. Flexible pavements are vulnerable to many permanent deformation and failures. Among many failures and distresses, rutting is a major and very important distress observed in a flexible pavement. Longitudinal distress along the wheel paths of the vehicles is attributed as rutting in flexible pavements, this may be an attribute of excessive consolidation, formed and caused by application of repeated heavy loads, movement of the materials in lateral direction and shear failure in the bituminous concrete layer. In this study an attempt is made to study the rutting characteristics in Bituminous Concrete (BC) layer and the efficiency of steel slag to reduce the rutting in BC layer using plain binder (VG-30) and modified binder (CRMB-60). Effect of steel slag has been studied by partially replacing stone dust with steel slag in the increments of 5 from 0 to 20％. From the Marshall Stability test values it was inferred that the optimum percentage of steel slag replacement is 10％ for both plain and modified binder. Using this optimum steel slag replacement and respective Optimum Binder Content (OBC) rutting specimens were casted with varying thickness of 50 mm, 75 mm and 100 mm with constant tyre pressure of 11.6 kg/cm2 and constant speed of 25 wheel passes per minute. It was observed that the rutting resistance is maximum in least thickness and the rutting coefficients (elastic and plastic coefficients) are converse to each other. |
