چکیده
Abstract In order to explore the rheological properties of high content warm mix recycled asphalt binder, was added into prepare asphalt. The optimum regenerant and Sasobit REDUX determined by basic performance test temperature scanning test. chemical composition studied FITR. low crack resistance were analyzed DSR BBR tests, determined. results show that when is 10%, its recovers level base can reduce viscosity asphalt, 1%. With increase content, shear modulus phase angle gradually decrease, stability increases. Under frequency conditions, with 50% has better deformation resistance. action stress, strain accumulation decreases When 50%, ability resist load sensitivity in middle zone similar matrix it good Comprehensive analysis best should be then mixture excellent road performance.

Modification 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...

The asphalt paving industries are faced with two major problems. These two important challenges are generated with an increase in demand for environmentally friendly paving mixtures and the problem of rapidly rising raw materials. Recycling of reclaimed asphalt pavement (RAP) is a critical necessity to save precious aggregates and reduce the use of costly bitumen. Warm Mix Asphalt (WMA) technol...
متن کاملA Study on the Rheological Properties of Recycled Rubber-Modified Asphalt Mixtures
Using waste rubber in asphalt mixes has become a common practice in road construction. This paper presents the results of a study on the rheological characteristics of rubber-modified asphalt (RMA) concrete under static and dynamic loading conditions. A number of static and dynamic creep tests were conducted on RMA mix specimens with different rubber sizes and contents, and a series of resonant...
