Agenda

2.) Sections 4.1 and 4.1.1 -- to be disregarded as they are solely intended for HMA.

3.) Section 4.2 — replaced in its entirety to read “Test Specimens — specimen length and
width must match Figure | (cutting template), and specimen height must be 0.50 in.
Make and cure the micro-surfacing overlay test specimens using similar methods and
resulting in similar mixture composition and mix consistency as done for the TB 100
(Wet Track Abrasion) and TB 147 (Loaded Wheel Test) specimens.

The water shall be potable and shall be free of harmful soluble salts.
Modifier

Special quick-setting emulsifier agents shall be milled into the asphalt emulsion. The emulsified
asphalt shall be so formulated that when the paving mixture is applied at a thickness of one inch
with the relative humidity at not more than 50% and an ambient air temperature of at least 75
degrees F, the material will cure sufficiently so that rolling traffic can be allowed in one hour
with no damage to the surface, as verified by the Engineer.
