Research And Development Services And Related Consultancy Services - Fe 07.0331/2025/Agb - Investigation Of The Effect Of Temperature Absorbing Technologies For Asphalt On The Layer Network. For Reasons Of Occupational Safety, Asphalt Mixing Goods Will Only Be Produced And Installed In The Future. It Was Shown On The Basis Of Workplace Measurements That The Emissions Significantly Reduce The Reduction In The Installation Temperatures Around 20 To 30 ° C. Due To The Strong Dependence Of The Asphalt Properties On The Installation Temperature, Various Methods Were Tested To Lower The Installation Temperatures. This Includes The Use Of Viscosity -Changing Organic Additives, On The Other Hand, The Use Of Surface -Active Additives And The Use Of Technologies To Enlarge The Binder Volume (Foambit Technology, Zeolithe) When The Asphalt Mixed Material Is Manufactured. Regardless Of The Execution Risk, It Is Still Unclear How The Changes Affect The Material Properties. It Is Conceivable That Lower Installation Temperatures Weaken The Layer Network And Consequently The Expected Service Life Of The Traffic Fortification Is Not Achieved. Inadequate Layer Network Leads To Premature Deformations And Structural Damage To Traffic Strength. As Part Of The Research Project, The Effects Of The Use Of Temperature -Resistant Asphalt Are To Be Systematically Examined On The Layer Network. The Aim Of The Research Project Is To Analyze Possible Influencing Factors Of Temperature -Defined Asphalt And Their Technologies On The Layer Network With A Sophisticated Examination Methodology In The Laboratory. Recommendations For The Rules In Germany Are To Be Derived From The Results So That Permanent Traffic Fortifications Can Be Made From Temperature -Tied Asphalt And A Requirement Network -Friendly Layer Network Is Guaranteed.
