摘要
沥青中掺以沥青重量计的0.05%~0.20%CT金属皂,沥青砂的抗压强度增加43%,对集料的粘附力提高2~3个等级,金属皂沥青的延度增加30%,脆点降低3~5℃。4年来,全川总计铺筑150万m^2的金属皂沥青路面,获得显著的社会经济效益。
The bitumen is modified by adding CT metalline carob of 0.05%--0.02%
of the bitumen by weight to give the bituminous mastic a 43% higher compressive
strength, and the adhesion of the aggregates in the mixture will be increased by 2--3
grade. The ductility of the CT metalline carob bituminous mixture is shown to be
increased by 30% while its brittleness is lowered by 3--5 centigrade. One and a half
million square meters of pavements have been built with the CT metalline carob
bitumen in sichuan in the past four years resulting in a remarkable social--economic
benefit.
