Asphalt plays a pivotal role in the infrastructure of Kalgoorlie, and investing in local asphalt companies offers numerous advantages. This local asphalt company in Kalgoorlie facilitates the construction and maintenance of critical infrastructure, including roads, highways, parking lots, and more. In this blog, we will explore why quality asphalt matters, its impact on road safety, the different types of asphalt we offer, and more!
Without further ado, let’s dive in!
Total Asphalt is the company to trust for quality commercial asphalt projects within Kalgoorlie, with over three decades of unwavering dedication and expertise in the industry. We provide:
Founded by Terry Hosking, Total Asphalt has evolved from a modest sole proprietorship to a thriving enterprise, boasting a team of 15 to 20 skilled professionals and a fleet of 30 cutting-edge equipment pieces. Our operational footprint extends across Kalgoorlie-Boulder, Wiluna, Esperance, Merredin, and Eucla regions in Western Australia.
At Total Asphalt, we pride ourselves on our versatility in catering to a spectrum of project scopes ranging from:
For those seeking reliability and expertise in asphalt contracting, Total Asphalt emerges as the undisputed choice. We ensure top-notch quality at competitive rates, thereby guaranteeing utmost customer satisfaction. Our track record speaks volumes about our commitment to delivering exceptional results backed by decades of industry experience.
Through our mobile asphalt batching plant, we can churn out between 40 to 80 tonnes of asphalt per operating hour, both in HOT and COLD mix variants. Additionally, we offer spray emulsion and hot bitumen services for single and two (2) sealcoating applications facilitated by our fully equipped vehicles.
Total Asphalt can manufacture asphalt for pick up and/or delivery to pre-determined sites at competitive rates. Also, certificates for mix samples can be provided if requested.
The process involves heating and mixing coarse and fine aggregates (crushed rock), filler (dust and/or hydrated lime), and bitumen in a batching plant to create a hot and robust mixture. Additionally, specialised materials can be incorporated during the production process to achieve asphalt with specific functions and enhanced properties.
Some of the additives used in asphalt production include liquid adhesion agents, red oxide for colouring, polymer modifiers, multigrade binders, and bitumen modifiers to alter viscosity. Furthermore, fibres, such as Kevlar, can be added to improve the fatigue and deformation characteristics of the asphalt.
On the Main Roads WA network, various types of hot mixed asphalt are utilised, each serving distinct purposes:
This is the most common type of asphalt and provides excellent structural strength and resistance to deformation.
Designed to drain water through the asphalt layer, OGA is used in high-speed applications, hilly terrains, and locations where effective water drainage is crucial for road safety.
Similar to OGA, SMA has a high proportion of dust and binder content, leading to improved fatigue life. It features a textured surface but does not drain water through its layer like OGA.
HMA stands as the cornerstone of our operations, blending approximately 95% stone, sand, or aggregate/gravel with asphalt cement. This concoction, heated at around 160 degrees Celsius, is meticulously crafted at our batching facility and then transported to the paving site for application. The subsequent spreading and compaction, facilitated by heavy-duty industrial rollers, culminate in robust pavements ready to withstand vehicular traffic soon after cooling.
Cold Mix Asphalt Concrete offers an alternative approach, produced by emulsifying the asphalt with a blend of cutter products before mixing it with the aggregate. Cutters are mixtures of Diesel, Jet A1 (aircraft fuel), or commercially produced oils like peanut oils. In its emulsified state, the asphalt becomes less dense, making it easy to work and compact. As the emulsion breaks and enough cutter evaporates, the cold mix adopts the properties of cold HMA.
Cold mix asphalt is commonly used as a patching material for asphalt repairs, including potholes, and is suitable for lesser trafficked service roads.
Total Asphalt's operational efficiency is further bolstered by our comprehensive fleet, comprising state-of-the-art equipment tailored to diverse project requirements:
Our arsenal is further fortified by cutting-edge asphalt plant and bitumen equipment, including:
This ensures seamless operations and uncompromised quality control.
Modern construction relies heavily on the use of asphalt. However, achieving a smooth and long-lasting asphalt surface requires a meticulous and well-executed laying process. Let’s cover the technical aspects of asphalt laying, from preparation to the finishing touches, shall we?
Before laying asphalt, it's crucial to prepare the subgrade properly. This involves removing any previous pavement, debris, and unstable soil. The subgrade should be compacted to reach the desired density, providing a secure foundation for the asphalt layer. Total Asphalt, a Goldfields-based company, follows AS 3798 and MRWA specifications for subgrade preparation to ensure compliance and quality work.
Then, an aggregate base material is laid and compacted over the subgrade to serve as a load-bearing foundation for the asphalt. The type and thickness of the aggregate base depend on factors such as traffic load and soil conditions. AS 2150 and MRWA specifications outline the requirements for granular materials used in road construction, which Total Asphalt follows to ensure quality installation.
Choosing the right asphalt mix is crucial, and AS 2150.2 and MRWA guidelines provide the necessary specifications for mix design. Total Asphalt tailors the mix design to meet project requirements while complying with these standards, ensuring quality work.
State-of-the-art paving equipment is crucial for achieving a high-quality asphalt surface, and AS 2749 and MRWA guidelines outline the requirements for such equipment. Total Asphalt uses equipment that meets safety and performance standards, ensuring compliance with these regulations during the laying process.
Proper compaction is crucial to the performance of the asphalt surface. AS 2150.3, in conjunction with MRWA specifications, provides guidelines for the compaction of asphalt mixes. Total Asphalt follows these standards to ensure uniform compaction and a durable asphalt layer suitable for the Goldfields Region.
Creating well-designed joints is essential for controlling cracking in the asphalt surface. AS 2150.4, complemented by MRWA requirements, provides specifications for joint construction and finishing techniques. Total Asphalt ensures proper design and execution to prevent common asphalt issues in line with these standards.
Throughout the asphalt laying process, rigorous quality control measures and testing should be implemented. AS 1141, AS 2891.2, and MRWA testing guidelines provide a comprehensive approach. Total Asphalt, as an industry-leading company, adheres to these standards to ensure the quality and integrity of the asphalt surface in the Goldfields Region.
