We recently had a two-phase paving project providing a good example of paint performance on newly paved hot mix asphalt concrete. On the above photograph there is a seam between pavements paved 45 days apart with three spray paint applications. At the top is fresh paint only hours old. The enlargement below shows a 15 mils thick application does not fill-in the voids. The bottom of the top photograph shows the condition of the 45-day old single striping. Note the white paint discoloration caused by the light oils in the asphalt cement bleeding into the paint.
Between the new and 45-day striping is a second paint application. The additional paint layer significantly improves the striping appearance and the additional thickness will improve durability. We typically don’t include a second application because an entire property re-striping is often scheduled within a short time after paving.
