Dynapac

For more than 50 years May Asphalt Group has been a leading supplier of asphalt services in Melbourne. The company provides a diverse range of solutions including asphalt paving/overlays, asphalt profiling/edge planing, consulting on civil projects, reinstatements works or asphalt crack sealing to roads and pathways, proving plant and labour hire.

May Asphalt purchased the Dynapac SD2500CS paver over one year ago.

“We decided to purchase the Dynapac paver because it produces higher compaction from its screeds as opposed to the American style screeds,” says Rick May, Managing Director of May Asphalt Group.

He adds, “The new paver has given us the opportunity to improve our efficiencies on large projects.”

SD2500CS Paver

The SD2500CS paver combines decades of experience with constant innovation. When designing this machine, Dynapac focused on the paving process and paving quality as well as increasing the reliability of the machines. The Dynapac SD range features the widest variety of choices: gas or electric heating, standard or high capacity work, 4 different power classes offering a sustainable drive concept, with Eco mode or an optional high performance system called VarioSpeed.

Quality

To achieve the best paving quality you need to rely on a high-performance screed, smooth material flow and an efficient, powerful drive. The paving quality is measured in compaction, evenness and profile – the Dynapac SD paver range will help you to achieve your paving goals.

Intelligence

Dynapac’s intelligent control system PaveManager 2.0 combined with the new 7” display provides you with excellent monitoring of the complete paving process and ensures an optimal material flow.

PaveManager 2.0 offers advanced features such as a real time paving parameter overview, paving parameter memory function and automatic crown and slope settings. Combined with additional sensors, PaveManager 2.0 can also display real-time layer thickness and working width data.

Safe Impact System™

The Dynapac SD tracked pavers offer the safe impact system™ – a hydraulic anti-shock push roller that avoids the typical marks on the surface due to truck docking. The system also extends the docking length and gives you flexibility when working with different truck models.

Traction

Our Alpha-Track™ system is longer and wider to give you a smooth drive behavior and a perfect grip. The rubber track pads are 320mm wide which creates great ground contact. A high number of rollers inside the tracks improves the manoeuverability on curves. The tracks are also very low to give an optimal dumping height. These track pads are especially designed for paving application and have higher rubber thickness for longer life and lower cost.

Material Flow

Dynapac has designed the hopper with chamfered hopper edges to avoid cold asphalt sticking in the corners. A hydraulic front hopper flap reduces material spillage on the push rollers and on the road. It also helps to completely empty the hopper and reduces the amount of hand shovelling required.

A very low dumping height makes collision with trucks almost impossible. The generous hopper leads to the widest conveyor tunnel on the market. The tunnel is shaped to create the best flow and to avoid any segregation of asphalt material.

The twin conveyor system, 2 x 655 mm wide, with reversible drive, offers smooth material flow without segregation. We have a standard conveyor as well as a high capacity conveyor with double the number of conveyor bars for improved material flow. The auger compartment is fully visible from the operator’s position. The auger and auger tunnel are easily extended to fit wider working widths.

Power Auger System

The Dynapac auger drive system is an improved centrally driven system with a slim gearbox (15cm) and small outer bearings that allow homogeneity of mixture, despite the high material throughput of up to 1100 tonnes per hour.

The left and right auger drives have independent and reversible controls. This strong auger system has a torque to handle auger diameters from 380 mm up to 500 mm. In order to achieve optimized material flow for different paving thicknesses you can adjust the auger height hydraulically up to 250mm while paving.
