Performance Evaluation of Hot and Cold Pour Crack Sealing Treatments on Asphalt Surfaced Pavements (Revised);Research rept

摘要

This study is a continuation of an ongoing process of monitoring performance of treatment procedures using two types of crack sealants. The main objective of the analysis in this report is to compare the long-term performance of hot pour sealants to that of cold pour sealants. For the purpose of this comparison four types of materials are used. These materials are: hot pour crack sealant, hot pour joint seal, cold pour crack sealant, and cold pour joint seal. Hot pour crack sealant is basically composed of rubber asphalt and cold pour sealant is composed of different asphalt emulsions.
