Sulfur Modified Warm In-Plant Recycling Asphalt Mix Design with High RAP Content
Using French high modulus asphalt mixture design ideas and Chinese local test equipment,the high RAP content Sulfur modified warm in-plant recycling asphalt mixture's mix design calculation for-mula and design process is localization.We also test the final warm recycling asphalt mixture performance ver-ification and find that warm recycling asphalt mixture can satisfy with Chinese local spec quality requirements for ordinary hot mix asphalt mixtures.The warm recycling mixture's high temperature performance and water stability performance can also satisfy with index requirements for SBS modified asphalt mixture.In the expan-ding performance test,the compression rebound modulus,split strength and fatigue life under small strain of sulfur modified warm in-plant recycling asphalt mixture is better than ordinary hot mix new asphalt mixture with the same mix design.
