WebNational Asphalt Pavement Association QIP 128 Best Practices for Emulsion Tack Coats 3 fIntroduction Long-term performance of an asphalt pavement is significantly related to the bond developed between successive pavement layers. To aid in achieving a bond between asphalt pavement layers, tack coat material is applied between pavement layers. WebPoor tack coat techniques result in compromised bonding of the asphalt layers. This leads to pavement distresses. Possible slippage cracking and delamination are associated with poor bonding. Additionally, poor bonding can lead to structural distresses, namely fatigue cracking and potholes. the joint redmond wa
