MMA Color Pavement Construction Process
Apr 30,2021

Mixing the MMA base material with BPO in the specified ratio, and vigorously stirred for 3-10 minutes to make the colors of the MMA base material uniform and consistent. Coat the MMA base material on the road surface and immediately use a screed blade to pave the required thickness; then evenly spread the colored anti-slip aggregates on it. The colored anti-slip aggregates shall completely cover the paint layer and shall not be spilled. According to the needs of different road sections, the anti-slip aggregates with suitable particle size should be selected. Generally, the coverage rate of the MMA base material is 1.5-2.5kg/m², and the amount of aggregates is about 8-12kg/m².





After the MMA base material is cured, use a powerful vacuum cleaner or a broom to remove the extra anti-slip aggregates to form a thin layer of color warning anti-slip pavement. The thin-layer color warning pavement requires dry and normal temperature maintenance after construction, no water, release the vehicles after 1-3 hours. When the temperature is lower, the road closure maintenance time should be appropriately extended. In order to protect the pavement surface, swept away the falling off aggregates after 3 days, and clean the pavement surface again after one week.
