Mode
Application:
Asphalt pavement
Concrete pavement
Bridges and parking Treatment crack
Cracks on the waterproof construction(1) determine the slot size
The slot size is based on the local pavement temperature and the road grade. Generally ,the width don’t exceed 38mm, depth of the groove should not exceed 25mm. The both sides of grooving should remove at least 3mm and should produce vertical, intact surfaces with no loosely bonded aggregate.
(2) Calculate the amount of material
According to the empirical formula, can use following formula :
Estimation method: width (cm) * depth (cm) * Length (m) * 0.12 (kg)
E.g. a slot pavement : 2cm(width) *2cm(depth)*10m(length ), then crack and joint sealants amount is: 2 *2 *10 * 0.12 = 4.8 kg
2. Grooving
Step one : design the slot size ;
Step two :adjust to grooving machine ;
Step three : construction
3.Clearing
For appropriate adhesion , cracks must be cleaned and dried before pouring. After grooving or cleaning impurities, and then use high pressure ,oil free ,dry compressed air at 90psi (620kpa )minimum ,to remove any remaining dust .
4. Preheating
It must preheat groove when the temperature is below 4°C.What we done just ensure the temperature above 10°C.
5. Pouring
Putting the crack and joint sealants into groove when the temperature reaches 185°C. It needs pouring severaltimes until the cracks filled.
6. Maintenance
Clearing the site after the Crack and Joint Sealants Sufficient cooling(about 15-25min).
it must be sprayed a layer of sand or powder If you need to open the traffic immediately.
Storage:
1. This product is non-toxic, non-dangerous goods, according to general chemical building materials transport.
2. The transit shall not exposure, rain, upside down or damaged packaging.
3. The product shelf life is three years (room temperature, airtight and dry storage).
