Not working condition: gameObject.layer==LayerMask.GetMask...

How can I check the object for several layers? The example below does not work! I want to have one variable where all the layers with which I want to compare the object can be written. This is more convenient than the NameToLayer

 LayerMask layersContact;
 
 void Start()
     {
         layersContact= LayerMask.GetMask("Road", "Terrain");
     }
 
 void Update()
     {
         if (gameObject.layer == layersContact)
         {
             Debug.Log("WORK!!!");
         }
     }
