Investigation into Role of Pavement Materials in Mitigation of Construction Defects and Cracking in Concrete Pavements

Project Member(s): Vessalas, K.

Funding or Partner Organisation: Ward Civil and Environmental Engineering Pty Ltd (Ward Civil and Environmental Engineering Pty Ltd Partner funds)

Start year: 2015

Summary: Ward Civil and Environmental Engineering (WCEE) undertake various pavement construction projects in the Sydney metropolitan area. Occasionally, during the construction phase, pavement layers do not achieve the necessary density requirements meaning that re-work is required. In addition, in service, pavements can exhibit cracking meaning that often the repair, or complete replacement, of the pavements is required. These defects can lead to significant repair and replacement costs being incurred by WCEE. The purpose of this research study is to examine the underlying root causes of these defects in order to help understand how these defects can be mitigated before the commencement of construction. A comprehensive literature review will be carried out and an experimental testing program will be implemented to better understand the suitability of different pavement materials for use in pavements, and their performance under different conditions. This study will focus on the following key outcomes: ¿ A comparison of different pavement materials ¿ Pavement design, construction and testing ¿ Maintenance of pavements
