1.  Preparation 

 

 

 

(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 several times 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.
