Section 3: Factors Influencing Performance

Anchor: #i1000235


The performance of seal coats and surface treatments depends on:

  • construction techniques used
  • properties of the bituminous binder and the stone
  • amounts of stone and binder used and the uniformity of application
  • development of good adhesion initially which must be maintained throughout the life of the surfacing
  • development of a dense interlocking mosaic of stone
  • strength of the underlying base or condition of underlying pavement
  • amount and type of traffic
  • environmental and drainage conditions.

These factors will be discussed in more detail later in this manual.
