Efficient asphalt-paving technology with only one motorized device

The low primary energy requirements and the resulting profitability speak for the use of DSK Asphalt. With DSK Asphalt’s thin film technology, the amount of raw materials required sinks by 50 percent – especially with the fulfillment of quality criteria which also apply to conventional asphalt. The asphalt mixing plant and the asphalt pavers are integrated into one motorized production device. This innovative technique saves on heating, which is unavoidable in conventional asphalt production. This way, the completely- integrated production and installation process can avoid excessive interim transportation. For the installation of the asphalt, neither pavers nor rollers are required. The technology makes it possible so that streets can once again be re-opened for traffic after only twenty minutes. Traffic still-stands and the time when a street must be closed can be reduced to a minimum. In principle, this means that time, effort, resources, energy and costs can all be saved while maintaining a high quality for the construction project.

The Advantages in Comparison to Conventional Procedures

• Resource conservation through optimal material usage
• Lower production costs
• Energy reduction – no heating of materials required
• Lower production emissions
• Efficient application as a continuously progressive construction site
• A clear reduction of additional work
• Quick return to regular traffic

The Environment Likes DSK Asphalt

Wherever conventional asphalt is used, there is a high burden on the environment. Raw materials, such as stone or bitumen, are transported to a stable mixing plant, and elaborately heated. Finally, trucks take over the transport to the construction site. Several machines are needed even here, in order to install and condense the mixed asphalt.
By using DSK Asphalt, the amount of greenhouse gas emission is greatly reduced. Through the low usage of raw materials and the elimination of mixed asphalt production in a stationary mixing plant and numerous interim transportations, the process is convincing with an up to 75 percent-better Co2-balance in production and installation. In the end, this environmentally-friendly construction method will reduce street noise and ensure that man and nature profit long-term from this innovative technology.

Optimal grip even after over 10 years

Everyone involved in traffic feel most comfortable when traffic runs smoothly. In this case, smoothly means with excellent grip. With its optimized formula, Microsurfacing fulfills the highest quality standards and offers outstanding grip even after 10 years of usage. For everyone involved, this means noticeable traction and abrasion resistance.

Permanent durability proven through long-term study

In order to prove the durability of Microsurfacing, various asphalt construction sites on the BAB A 659 were observed in a long-term study between 1990 and 2005. The results of the monitoring speak for themselves: among the individual repair process, no significant difference in deterioration could be found. Both the quality of material as well as the skid resistance of Microsurfacing could produce comparable results to conventional asphalts after 15 years of usage. Therefore, the longevity of Microsurfacing in comparison to conventional construction methods has been clearly proven.

A new road surface in only 20 minutes

Complex and lengthy periods of construction are a burden for everyone involved in traffic. Through innovative technology, Microsurfacing reduces this burden to a minimum. The reason: Merely a continually manufacturing production unit is needed in order to renew the road surface in a steadily-progressing moving roadwork. Time-consuming work on the side, roadblocks and lengthy traffic jams are a thing of the past. The roads can be opened again for traffic a mere 20 minutes after construction.

The benefits of this process at a glance:

• One vehicle takes care of all work stages (mixing, application, compressing)
• Hardly any work on the side necessary
• Requires only a small workforce
• Minimal amount of traffic still stand
• Street blockades only necessary for a short period of time
• Quick re-opening of the road after only 20 minutes
