Evaluation of Rutting in HMA Mixtures Using Uniaxial Repeated Creep & Wheel Tracker Tests
نویسندگان
چکیده
Over the past twenty years; road traffic (both passenger and freight) has grown significantly in Pakistan. Higher axle loads and repetitions have resulted in premature rutting of flexible pavements. Rutting, in the form of shear flow is a typical distress that mainly attributed to increased tire pressure, high temperature and heavy axle loads. Consequently, National Highway Authority (NHA), Pakistan is facing challenges due to frequent pavement failures, high maintenance costs and poor riding quality of pavements [1]. Laboratory characterization of asphalt mixtures is thus very important [2]. True prediction of asphalt material behaviors a5d their precise selection on the basis of laboratory performance can be one of the solutions towards this chaotic problem.

Investigation of Rutting Performance of WMA Mixtures Containing Copper Slag
Copper slag (CS) is an abrasive blasting grit made of granulated slag from metal smelting processes. As copper slags are known to be waste material and cause a lot of environmental problems, it would be a good idea to use them in different sections of industry such as pavement construction. On the other hand, in order to save energy and reduce the amount of pollutants re...
متن کاملImpact of Aggregate Gradation and Type on Hot Mix Asphalt Rutting In Egypt
Rutting of flexible pavement is considered one of the major pavement distresses noted around the world and in Egypt. Many investigators showed at about 55 to 80% of rutting occurred in the surface layer. Rutting of asphalt surface layer may be due to many causes happened during construction phase and service phase. The main objectives of this research are to evaluate the impact of aggregate gra...
متن کاملModification of the Properties of Warm Mix Asphalt Using Recycled Plastic Bottles
Construction of flexible pavements with hot mix asphalt (HMA) mixtures consumes huge energy which impacts the resources and the environment of the world. Warm Mix Asphalt (WMA) is an effective alternative as they produced with lower mixing and compaction temperature than those used in HMA production. This technology decreases energy consumption, saves money, and reducing the environmental pollu...
متن کاملMODELING OF FLOW NUMBER OF ASPHALT MIXTURES USING A MULTI–KERNEL BASED SUPPORT VECTOR MACHINE APPROACH
Flow number of asphalt–aggregate mixtures as an explanatory factor has been proposed in order to assess the rutting potential of asphalt mixtures. This study proposes a multiple–kernel based support vector machine (MK–SVM) approach for modeling of flow number of asphalt mixtures. The MK–SVM approach consists of weighted least squares–support vector machine (WLS–SVM) integrating two kernel funct...
متن کاملAssessing rutting susceptibility of five different modified asphalts in bituminous mixtures using rheology and wheel tracking test
Rutting is one of the most important distresses in asphalt pavements due to its frequency. Rutting or channeling, could be classified in three types: 1) mechanical deformation (rutting in subgrade or base), 2) plastic flow (unstable asphalt layer), and 3) wheel path consolidation. The plastic flow of bituminous mixture depends on many factors; one of this is the type of asphalt used in the mixt...
