The property quality of the modified asphalt can meet the demand of JTJ 036-1998 standard awarded by the Transportation Department. The penetration degree is 111 (0.1 mm) at the temperature of 25 ℃, the softening temperature is 85.3 ℃, the ductility is 102 cm at the temperature of 5 t, the elastic recovery is 96% at the temperature of 25 ℃, kinematic viscosity is 1.7 m2/s at 135 ℃.
The elastic recovery percentage of the treated floss silk is 92.37%～97.66% and the compression ratio,59.21%～66.77%,both are superior to the criteria set by the textile industry for the superfine wadding floss silk.
The results show that ceramic coatings possess three layers transitional, dense and loose layer, composed mainly of rutile TiO2 and a small amount of anatase TiO2. Elastic recovery is 40.5% and 14.9%, hardness is 8.54 GPa and 5.5 GPa, and elastic modulus is 87.4 GPa and 150 GPa in the dense layer and the substrate, respectively, The MAO coating indicates pronounced ceramic characteristics.
Its tableting characteristicswere disclosed by observing the relationship between tableting pressure andmax radial force, residual die wall force and the ratio of elastic recovery,and the diagrams of stress relaxation as well as Heckel plots.
The working time was defined as the time when initial elastic recovery of the material was observed at 23 ℃. The setting time was the time when the elastic recovery reached a final constant value at 37 ℃.
The outer solution describes the long term behavior of the elastic recovery, and a bound on the ultimate recovery is determined.
The inner solution describes the process during a boundary layer in time which occurs at the onset of elastic recovery.
By reducing the magnitude of the compressive effective stresses the fluid pressure causes elastic recovery in fractures.
The test provides reproducible data in terms of indentation modulus, elastic recovery, scratch penetration depth, and scratch residual depth, and also offers the possibility of detecting critical mechanical transitions such as rupture.
The determination of elastic modulus values via the Knoop indentation technique is based on the measurement of elastic recovery of the dimensions of the Knoop indentation impression.
