In recent years，As China's road industry gradually turned to maintenance-oriented.、Phase supplemented by new construction，As one of the most cost control forward-looking technologies in preventive maintenance,，Asphalt ultra-thin overlay construction has been more and more widely used.，And related new materials and new technologies are springing up like bamboo shoots after a spring rain.。
Recently, we learned that，In the just-completedSPavement Maintenance Project of Linzao Section of Lanzhou-Heze Expressway，Six new materials for ultra-thin paving are used，Creating the record of ultra-thin overlay construction in Shandong Province，Dynapac's complete set of high-tech compaction and paving equipment provides equipment guarantee for the smooth implementation of the new technology.。
SLinzao Section of 38 Lanzhou-Heze Expressway is an expressway network in Shandong Province.“Five vertical、Four horizontal lines、One ring、Eighth Company”Medium“One ring”An important part of，It has been in operation for 10 years since its completion and opening to traffic.，With the great increase of traffic volume,，The road surface is seriously damaged.。Designed and reviewed by experts，It is decided to adopt the construction scheme of directly paving ultra-thin overlay.，And in ord to ensure passage,，Carry out half-width closed construction。In terms of equipment，Through comprehensive consideration，DynapacSD2530CSPavers andCCThe 6200 double-drum roller is the golden combination of high-grade pavement construction.，It has the characteristics of high efficiency, fast operation and high-tech content.，It has become the first choice of the construction party.。
To achieve the best construction effect，Shandong High Speed Maintenance Group Co., Ltd. is the exclusive distributor of Dynapac in Shandong Province.——With the help of Jinan Rio Tinto Construction Machinery Co., Ltd，The ultra-thin overlay process of six new materials is adopted，This includes more than justSMA-8 High toughness material、 Luffite Super Wearing Course Technology、ARC-8 Super Tough Wearing Course System、Elephant mute type ultra-thin cover、Durable high-viscosity and high-toughness thin layer cover，Also included is the brand newZTSConstruction Scheme of High Elastic Anti-crack Ultra-thin Overlay。
ZTSHigh-elastic anti-crack ultra-thin overlay technology adopts direct castingZTSHigh elastic anti-crack additive，Convenient and fast，The special modified asphalt used in the traditional ultra-thin overlay technology is no longer needed.。SutraZTSAfter modification，The performance of asphalt mixture has been greatly improved，Thereby remarkably improving the deformation coordination capability of the ultra-thin overlay.、Resistance to water damage and cracking，Make the road surface more flexible。
At the same time，For 1.5cm-2.5cmHigh standard for construction of ultra-thin asphalt layer，Shandong High Speed Maintenance Group Co., Ltd.，Still cast a vote of confidence in the equipment to the Dynapac brand, which has cooperated for many years.。SD2530CSPavers andCCThe paving and compacting partner of 6200 Road Roller is the first choice for high-grade pavement construction.，It has been tested by various projects.，Never a disappointment.。
DynapacCC6200 double-drum roller is the most reliable choice for road compaction quality。In addition to the original high frequency and low amplitude vibration compaction technology，For the special needs of ultra-thin wear lamination operation，CCThe soft start-stop function of 6200 can ensure smooth and uniform stacking when rolling extremely thin surface course.；Overall layout thanks to excellent articulated design，And the left and right sides of the front and rear wheels are provided with the reasonable arrangement of the driving motors.，CC6200 in the turning process of rolling ultra-thin asphalt layer，It can effectively avoid the phenomenon of cracking the road surface.；Intelligent Sprinkler system can be controlled by precise sprinkling amount.，Has a positive effect on reducing the temperature of the ultra-thin asphalt layer。
SD2530CSIt is the most mature large asphalt Paver model of Dynapac.，Known for Dynapac's outstanding patented technology screed and advanced operating control system，With its excellent paving effect and stable quality output, it has won a wide reputation in China and even in the European and American markets.。
High-performance Dynapac pavement equipment，It is the best partner of customer groups focusing on construction quality.，With its own excellent performance, it has brought greater possibilities for the innovation of various construction technologies and processes.。The diligent pursuit of high technology in the field of road construction，Achieved the value fit between Dynapac and Shandong High Speed Maintenance Group Co., Ltd.，It has also jointly created one after another examples of high-tech projects for the road administration of Shandong Province.。
