WebBecause polymer-modified binders are more viscous, pumping times may be slower and performance of some asphalt metering systems may be affected. Dense-graded polymer-modified HMA mixtures often require higher mixing temperatures - typically 300 to 350°F (149 to 177°C). Mix production rates may be reduced if the polymer-modified binder WebIt was also noted that successful porous friction courses were attained with SBR Latex Polymers. METHODS OF MODIFICATION. Another advantage of using SBR Latex Polymers as an asphalt modifier is that they can be added to any stage of the paving chain – from the refinery to the on-site job location. Major changes in technique are not required. shrek image id for roblox
