Powder-Cement Ratio Affects the Overall Performance of the ATB

Article Preview

Abstract:

Powder-cement ratio plays a key role in asphalt mixture. Only after asphalt adsorbs the surface of mineral powder to form a thin film, asphalt produces the adsorption on aggregate, so slag asphalt is real asphalt binder. Powder-cement ratio is different, road performance is different too. Through laboratory test, analysis powder-cement ratio reflects on heat, cold, water stability and anti-reflective cracks of ATB, make a range of radio of filler to bitumen, in order to provide a reference for the design of ATB composition.
