Haul road specialist Proof Engineers has developed an advanced road building program using the latest technology to design and construct haul roads that can handle high volumes of heavy vehicle traffic and withstand weather erosion.

Launching new technology for the design and construction of haul roads, Proof Engineers' Haul Road Development Program (HRDP) focuses on innovative practices to produce durable, high-quality roads that reduce maintenance costs, while improving operating speeds and wet weather recovery.

The cutting-edge program encompasses all aspects of building haul roads, from site analysis and resource evaluation through to material selection, training and maintenance monitoring.

Proof Engineers is an Australian-based company that utilises state-of-the-art technology to deliver road engineering of a superior standard on a global scale.

Specialising in haul road performance and optimisation, Proof Engineers improves mine sites’ operational efficiencies specifically through haul road design, construction management, maintenance programs and monitoring solutions.

Proof Engineers’ engineering and technologies manager Jordan Handel said the HRDP’s construction methodologies were achieving high-quality roads within their clients’ budget and equipment limitations.

“Our latest design technology is used to construct roads with improved strength, functionality and drainage,” he said.

“Roads developed with HRDP have optimal rolling resistance and require significantly less maintenance, which adds up to considerable savings for our clients.

“Haul roads constructed with our HRDP require up to five times less maintenance compared to a poorly-constructed haul road.”

HRDP consists of four essential steps in order to achieve quality roads within a mine operation’s budget and equipment limitations.

The first step is a full site evaluation, focusing on meteorological and environmental conditions that will impact design and construction, as well as the available resources to determine if the site has adequate equipment, raw materials and local skills, or if outside resources are required.

Step Two of HRDP evaluates and analyses all design parameters and utilises innovative technology to generate a mechanistic design that considers the selected materials and site-specific traffic conditions.

In this step, Proof Engineers considers the use of stabilisation products such as polymer additives, hydrated lime and bitumen emulsions to improve the quality of local materials in order to reduce costs.

The third step of HRDP is the construction phase; a site-tailored process involving drainage and compaction as well as the training of site personnel.

Step Four involves ongoing maintenance to ensure haul roads are operating at a high level, with ongoing training of site personnel to ensure roads are correctly maintained and not further damaged in the long term.

“The HRDP was developed by Proof Engineers on the premise that proper construction of quality haul roads will significantly reduce a mine site’s maintenance costs as well as decrease production cycle times,” Mr Handel added.

“The Program involves all aspects of haul road construction with a focus on material selection and construction methodologies that meet the highest standards based on optimum engineering properties such as functionality and strength.”

Proof Engineers is a leader in haul road solutions for mining operations, specialising in maintenance machinery management, functionality design and cutting-edge construction methods to build and maintain long-lasting haul roads.

The company has developed state-of-the-art road condition monitor (RCM) and dust monitor (Dustective) systems for mine operators to observe road conditions, prioritise maintenance works, improve operational efficiencies and reduce production cycle times.

The Proof Engineers’ team has a broad range of skill sets from practical, hands-on site personnel to research and design engineers, with experience in the civil and mining industries as owners, contractors and consultants.
