Kleinfelder was engaged to provide contaminated land investigations and geotechnical review, pavement assessment and intrusive investigation studies at three transport and infrastructure project sites within the Lake Macquarie City Council area.

Project Overview

To provide an acceptable level of service at the three sites and their intersecting local roads into the future, the client is looking to assess current pavement condition and identify required improvements needed to ease difficulties in accessing and exiting the current road corridors, both from intersecting roads and increased traffic volumes.

Kleinfelder Methodology

Kleinfelder undertook feasibility level studies of the geotechnical aspects at the sites and identified any geotechnical constraints to improvement works. Pavement condition assessment was also undertaken by visual inspection and Benkelman Bean tests were conducted.

Following inspections, the current pavement at all sites was found to be in poor condition, with extensive cracking, depressions, heave, polishing, and crocodile and longitudinal cracking. Sites also had either no or unsuitable guttering and all road pavements were well beyond their design life and in need of remedial action.

Project Results

Kleinfelder’s report to the client identified pavement construction requirements, including pavement materials, subgrade preparation and drainage. At one of the sites, general geotechnical aspects were identified as conducive to improvement works; however, specific geotechnical constraints were identified.
