SGS Pounding Pavement Down Under

In June 2012, Australian MacMahon contracted SGS to provide complex pavement engineering services for an asphalt beam recovery project in Perth. For the six weeks from the middle of June until the end of July, SGS experts conducted pavement and sub-grade testing investigations.

Headquartered in Perth, MacMahon is a leading Australian contract mining and construction company with operations throughout Australia, New Zealand, Asia, Mongolia and Africa. Macmahon has played a starring role in the execution of many of the largest Australian multi-disciplinary construction and mining projects for almost fifty years.

In the endeavor to ensure a quality completion of the roadworks in Perth, Macmahon sought a trusted and experienced partner for independent testing and certification. Based upon extensive experience and expertise in this area and a successful past cooperation, SGS was once again the clear choice to partner in this particular project.

SGS was entrusted to examine pavement and sub-grade testing, test construction material and perform geotechnical investigation for the Macmahon Perth asphalt beam recovery project, the second of its kind in all of Australia.

SGS Testing Methods Guarantee “No Worries”

SGS expert investigation of pavement and sub-grade testing services were carried out to ensure the quality and sustainability of the pavement systems. SGS conducted testing of construction materials including soils, rocks, concrete to guarantee quality and avoid costly repercussions of implementing substandard construction components. SGS geotechnical specialists analyzed soil, aggregates and subgrade material properties.

Highly-skilled SGS professionals used deflectometer laser profiling (DMLP), applying 3-D laser sensors to analyze pavement profiles by measuring surface roughness, texture and rutting at speeds and determine pavement compliance with international standards.

SGS engineers used falling weight deflectometer (FWD) technology to evaluate the physical properties of the Perth project pavement. FWD allowed SGS to measure the capability of the pavement to tolerate expected loads by measuring the vertical deflection response of the surface to an impulse load. SGS utilized deflection sensors to measure pulse waves in order to determine the strength of the surface material.

The South African deflectometer cone penetrometer (SADCP) was also used in the SGS testing of the Perth pavement to estimate the bearing capacity and modulus of compacted materials.

In addition, the team of SGS experts analyzed pavement samples, classified asphalt and tested aggregate strength.
