Because of the overload and channelization traffic, polymer modified asphalt as a high performance asphalt material is widely used in highway construction.
High Temperature Performance of Asphalt Mixture Modified by Natural Asphalt As a viscoelastic material, asphalt will be destroyed because of the excessive deformation under high temperature and heavy traffic conditions.
Raw Material and Mixture Gradation 1 Raw Material The test result of the A-70 asphalt and SBS (I-D) modified asphalt is shown as table 1 and table 2.

After detonate, dynamic effect of stress wave produced damage in material, and strength of material fell quickly, when stress wave travel to free surface and it is reflected to center of explosion, the dynamic effect is over, and the static effect of explosion gas is start.
Pressure of explosion gas overcome strength of damaged material and resistance of re-bar, break stone is shot off, and blasting crater is formed.

Absorption effective degree of microwave energy by material relatives to its frequency, every kind of material has specific frequency, in which it can best absorb effectively.
We have no idea that each material’s absorption peak will appear in what specific band, so we have to scan in a broadband.
We found out the distribution of material’s absorption frequency in the initial research.
