Comparison of Methods to Retard Reflective Cracking in Bituminous Concrete Using Fabrics and Fibers: Construction and Early Performance Report

摘要

The primary purpose of the project is to determine whether any of various treatments, using geotechnical fabrics and fibers, will significantly retard reflective crack formation in an asphaltic concrete overlay. Four paving fabrics, one asphalt/fiber membrane and one fiber-reinforced asphalt concrete, are the treatment alternatives being evaluated. All treatments are being compared with each other and a control section without treatment to determine relative performance, considering cost, ease of placement or adaptability to normal overlay practice, and ability to resist reflective cracking. Field monitoring is being maintained for three years to determine overall and relative performance of each treatment.
