A.该沥青属于70号沥青 ÿ{ð†'4¥bbs.3c3t.com×6‹ uÁð '
B.实测结果与真实结果相差的原因在于检测室温度偏低或针贯入时间偏长造成 ÿ{ð†'4¥bbs.3c3t.com×6‹ uÁð '
C.如以实测结果确定的标号作为沥青选择的依据,配制的沥青混合料有可能引起髙温稳定性不良的问题 ÿ{ð†'4¥bbs.3c3t.com×6‹ uÁð '
D.按照实测结果所表示的沥青黏稠度要大于实际沥青的黏稠度 ÿ{ð†'4¥bbs.3c3t.com×6‹ uÁð '

B.软化点加热升温速率要控制在5℃±0.5℃的范围，如超出该范围，试验结果将会偏高 ÿ{ð†'4¥bbs.3c3t.com×6‹ uÁð '
C.沥青高低温与延度值大小有关 ÿ{ð†'4¥bbs.3c3t.com×6‹ uÁð '
