Surface treatment is the application of an asphalt emulsion on either an existing asphalt road or a fresh, compacted granular surface immediately followed by the application of a cover aggregate.
It provides an economical all- weather surface for light to higher volume traffic depending on the emulsion and quality of aggregate used. It also provides a waterproof barrier that prevents the intrusion of moisture into the underlying materials and provide a skid resistant surface. It gives new life to a dry, weathered surface. A weathered, raveled pavement can be restored to useful service by application of a single or multiple surface treatment.
The asphalt emulsion is a mixture of asphalt cement, water, and an emulsified agent. It's composition is approximately 66% AC, 33% water and 1% emulsifier. It is applied with a computerized distributor, at rates varying from 1.30kg/ m 2 to 2.00kg/ m 2 . The most commonly used emulsions are HF150, HF150P (Polymer), HFMS-2, and CRS-2. Other emulsions are available for specific applications.
The Aggregate is divided into six different classes.
- Class 1- washed chip
- Class 2-comparable to 5/8 crusher run
- Class 3- HL4
- Class 4-Commonly known as a sand seal
- Class 5-fine washed chip
- Class 6- HL3
It is applied with a computerized chip spreader at rates varying from 12kg/ m 2 to 22kg/ m 2 .
These operations are immediately followed by rubber tired rollers, and depending on the application, a steel drum roller.

What is one advantage of using asphalt and one advantage of using concrete as the wearing course of a road?
One advantage of using asphalt as the wearing course of a road is its flexibility, which allows it to better withstand temperature fluctuations and heavy loads without cracking. In contrast, one advantage of using concrete is its durability and longevity, as it can last longer than asphalt under similar conditions and typically requires less maintenance over time.
