摘要
介绍了基质沥青掺配不同比例天然湖沥青后的针入度、软化点、延度等试验,以及沥青混合料相关试验。结果表明TLA改性沥青的采用提高了沥青的高温性能,低温性能基本不变,并可有效提高高温抗车辙性能。
The paper introduces experiments of penatration, softening points and extension of matrix asphalt which the natural lake asphalt with different proportion is admixed into, the some experiments correlative to asphalt mixture have been made as well. Results explain that application of TLA modified asphalt could increase the performance of asphalt at high temp and low temp, further more enhance rut - resistance at high temp.
