| Abstract: | A inbuilt-enveloping glue was developed successfully by using the materials such as PPT,TDI. The glue has some technical characteristic such as great elongation,high elasticity,strong adhesive power with concrete,adjustable color,fitting surface-drying time,tolerably working on the condition of moist slot,and so on. Major properties of the glue are superior to the alike domestic products,so it was applied on a few concrete roads in Gangdong province and gained well technical effect. |
