Brief Project Description & Background
The thin surfacing has been touted as one of the most cost-effective measures that can extend the life of pavements. Thin surfacing like the ultra-thin bonded bituminous surface (Nova chip) and modified slurry seal (micro-surfacing) are being increasingly used by some states. . However, the life extended by these treatments is not precisely known and thus, it can not be used in value engineering. Thus a study is needed how these thin surfacing can extend the life of pavements with high truck traffic.
The research objective would be to identify the existing pavement condition and truck traffic volume at which a certain thin surfacing treatment would be effective in lengthening pavement life.
The project is expected to produce recommendations regarding use of thin surfacing for high truck traffic routes. The most potential type of thin surfacing for a given existing pavement condition and truck traffic volume will also be identified.
