Performance and assessment of modified cold recycled asphalt emulsion mixture
In this study, the comprehensive performance of cold mix asphalt (CMA) is evaluated by seven laboratory test methods, namely the Hveem cohesion test, water immersion splitting test, freeze–thaw splitting test, indirect tensile fatigue test, semi-circular bending (SCB) test, dynamic modulus test, and rutting test. The CMA is modified using the regenerant (RE), Buton rock asphalt (BRA), and styrene–butadiene rubber (SBR) latex. In addition, we have proposed an evaluation model based on the grey target theory to quantitatively assess the effects of the modification approaches. The results show that the CMA modified with 8% RE has the best comprehensive property. RE is a potential modifier and reduces the content of emulsified asphalt for CMA, which can significantly improve the cohesion, moisture susceptibility, dynamic mechanical properties, and durability of CMA. Additionally, the grey target theory is an effective method to evaluate the comprehensive performance of CMA quantitatively.
