由于泡沫沥青处于非稳定状态,其膨胀与衰退过程具有较强的瞬态特征,真实地测量与评价泡沫沥青性能比较困难.为此,从泡沫沥青时空并行发生的机理角度,运用积分反推算法制订了两类泡沫沥青真实的衰减方程,提出了基于试验数据的理论膨胀率和理论半衰期的真实评价方法,通过沥青发泡试验验证了该评价方法的有效性,并从工程应用的角度制定了泡沫沥青理论评价的测算流程.

The process of expansion and attenuation of foamed asphalt has strong transient characteristics due to its non-steady state,it is hard to measure and evaluate the real performance of foamed asphalt.The real attenuation equation of foamed asphalt by using integral-back stepping method is established and theo-retical calculation of expansion ratio and half-time of foamed asphalt are performed based on experimental data.
