Overview

PCMA 100(Polymer Cool Mix Asphalt) is an asphalt paving method that produces less carbon and saves energy as it is produced and paved 40~60°C(110±10°C) lower than the traditional hot mix asphalt.

Properties

Mechanical Properties	Production Properties	Construction Properties
Application of Polymer Cool Mix Asphalt modifier(PG 76-22) Excellent dynamic stability Strong resistance against rutting and crack Excellent moisture resistance	Decrese of production temperature Energy saving Carbon dioxide reduction Emissions(SOx / NOx) reduction	Decrease of compaction temperature Early Opening to Traffic(EOT) Expansion of construction period

Uses

01Roads with heavy vehicles
02Industrial areas
03Highways and motorways
04Bridges, overpasses and underpasses
05Residential areas
06Densely populated areas

Production Standards & Quality Standards

01Base asphalt uses PG 62-22 asphalt (improved to PG 76-22 by using Zero-M)
02Asphalt mixture production temperature of PCMA 100 is 110±10°C, which is reduced by more than 40~60°C compared to existing asphalt.
03PCMA 100 exceeds the quality standard of modified asphalt by Ministry of Land, infrastructure and Transport of Korea

Traffic Opening and Construction Properties

▣ Construction Properties

01Application of the same construction equipment and construction method as for general asphalt pavement
02The paving temperature of the asphalt mixture is 110±10°C and the compaction temperature(macadam) is 100±10°C
03Opening to traffic is carried out when the surface temperature is below 40℃

▣ Traffic Opening Time(based on 40℃)

01Hot mix asphalt : (When producing 165℃ asphalt mixture) average 7 hours and 30 minutes
02PCMA 100 : ( When producing 110±10℃ asphalt mixture) average 5 hours and 30 minute
