Thermal shock resistance is an important index to evaluate the damage resistance of materials when they are subjected to rapid temperature changes. The closer the fingers are, the higher the precision. On the contrary, the lower the precision, the better the ability to resist damage. It was once called thermal stability, thermal shock stability, thermal shock resistance, temperature shock resistance, and cold shock resistance.

Main factors affecting thermal shock resistance of products:

(1) Raw material performance

(2) Amount of adhesive

(3) Wet and dry mixing temperature (wettability of asphalt to particles)

(4) Homogeneity of materials

(5) Impregnation

(6) Final temperature and holding time of heat treatment (calcination / calcination / graphitization)
