Using the DSR to test complex shear modulus G* and phase angle δ, then to get G*/sinδ value, to evaluate high temperature performance of warm mix asphalt mortar, the test data is showed in Table 4, where: A-70# asphalt, S-Sasobit, 0.6... 0.9- filler-bitumen ratio, 3-Sasobit dosage is 3%, the same below.
Fig. 1 The G*/sinδ value of different filler-bitumen ratio ② When the filler-bitumen ratio is same, the G*/sinδ value of asphalt mortar and warm mix asphalt mortar are increased following by the increasing temperature, and the higher the temperature, G*/sinδ gap is decreasing, namely asphalt mortar and warm mix asphalt mortar high temperature stability lower, the higher the temperature, the greater the reduction of high temperature performance, this is because temperature increases, δ becomes larger, asphalt viscosity performance has become increasingly apparent, the increasing of asphalt viscosity composition reduce the mineral filler of the asphalt impact to flexible components, thus appear reduce growth situation, as shown in Figure 2.

While in the cutting process, particularly when the workpiece hardness is higher than HRC55, the tool is vulnerable to suffer the wear, resulting in the reduction of its durability[2].
Conclusions In order to improve tool life, reduce processing costs and improve processing efficiency, this paper aims at dealing with the relation between the axial force and the cutting parameters, thus a regression model of the axial cutting force based on the experimental data is established.

The intensity in white line in the case of sample 3B is minimum which may indicate the minimum iron oxide yield and the reduction into metallic Fe.
In order to quantify the amount of each phase in the samples, the linear combination fit were calculated using XANES data of standard reference materials.

Since acetic acid is one of the major components in bio-oil, it has often been used as a model compound of bio-oil and study of acetic acid can provide valuable data for hydrogen production from the real bio-oil.
By increasing WAMR, hydrogen and CO2 concentration could be increased along with a reduction in CO and CH4 concentration.
