Asphalt and Sprayed Seal Road Surfacing Operations

Road surfacing determines how long a road lasts, and premature ravelling, bleeding and potholes usually start with poor control during laying. This course focuses on asphalt and sprayed seal operations for road construction and maintenance. It covers mix and binder selection, temperature control, rolling and the site checks that produce durable surfaces in African climates.

What you will be able to do

  • Select appropriate asphalt mixes and seal binders for conditions.
  • Control surface preparation, priming and tack coats.
  • Supervise laying temperatures, thickness and joints for asphalt.
  • Manage aggregate spread rates and binder application for seals.
  • Direct rolling and compaction to achieve target density.
  • Inspect finished surfaces and diagnose surfacing defects.
