However, the cost of double seals is obviously higher. 3.4 Selecting the Aggregate Size The chip seals described in this manual are single chip seals consisting of one application of asphalt emulsion and one layer of aggregate chips.

3.5.1 Surface Texture The texture of the pavement surface must be known prior to chip sealing so that an adjustment can be made for the design emulsion spray rate. Texture of the surface can be measured using either sand patch (ASTM E 965)

3.6.1.3 Soundness Freeze–thaw resistance and weathering are not common performance issues for chip-seal aggregates because water should drain freely from the surface of chip seals. However, magnesium and sodium sulfate loss tests (AASHTO T 104)

These properties are discussed below. 3.6.2.1 Flakiness The flakiness index, a measure of the percentage of particles that are long and slender in comparison to the width, is used in many designs of chip seals.

3.6.3 Emulsion Properties The properties of the emulsion used for chip seals are important and should be checked to ensure compliance with requirements. Desirable emulsion properties are provided in Table 6.
