Performance And Cost-Effectiveness Of Chip Seal And Microsurfacing In Flexible Pavements, Mohammad Zobair Ibne Bashar

LSU Master's Theses

Chip seal and microsurfacing are pavement maintenance activities typically used in relatively low traffic roads with the aim to reduce the rate of deterioration and to defer the need for costly rehabilitation activities. Chip seal is widely used in Louisiana, and Louisiana’s $6.3 million microsurfacing program is amongst the largest microsurfacing programs in the United States. As these surface treatments seal the road surface, the effectiveness of this treatment in such a setting has been a concern in recent years by linking it to moisture damage caused by the trapped moisture underneath the pavement. Furthermore, the cost-effectiveness and optimal timing …
