This is a method for gently stripping away the existing asphalt pavement from steel deck slabs by harnessing electromagnetic induction heating (IH) technology to heat steel deck slabs and soften the adhesive layer underneath the surface of the asphalt pavement.

In asphalt paving work performed on bridge deck slabs, this technology analyses reference height images captured by video cameras to automatically control the height at which pavement is laid and leveled by asphalt pavers.

This construction method involves building a composite rigid layer on the subgrade using a high-strength geo-grid and restraining members. It prevents the pavement from collapsing due to an earthquake and inhibits the formation of cracks and bumps in the asphalt pavement road surface. This allows emergency vehicles to travel on the road immediately after an earthquake, thereby helping to accelerate the initial response to any urgent call to save lives and transport supplies.

This is a split (stone) mastic asphalt pavement with improved watertightness, a feature of SMAC, as well as an improved composition for waterproofing. In order to sufficiently compact the mixture and ensure impermeability, Foam Set, a special additive used in Ecofine, a Warm Mix Asphalt, is used for the purpose of improving workability.

This pavement is laid down by pouring a high-temperature, highly fluid gussasphalt mixture. It is generally used for waterproof layers on deck slab pavement for steel bridges. Rolled Gussasphalt for surface layers with pre-coated chips press-fitted to improve flow resistance and slip resistance is also available.

This modified gussasphalt mixture delivers improved performance over conventional gussasphalt mixtures. This mixture combines excellent flow resistance and flexure-tracking properties with reduced amounts of generated odor characteristics of conventional gussasphalt.

This is the road bridge slab waterproofing method that can be expected to provide exceptional waterproofing and reinforcement effects through the combined use of a highly permeable waterproofing material that deeply penetrates into and adheres to penetrating cracks and fine cracks in concrete slabs and an asphalt-heated coating for the waterproofing material. Because application and curing times are short, this method is suitable for repairing bridge surface pavements where time constraints apply.

DL Pave is the pavement to be laid two different asphalt mixtures across separate upper and lower layers at the same time and compacted by rollers. For laying the asphalt mixture, it is done by using a two-layer simultaneous paving asphalt paver “DL Paver” and a material feeder “Asphalt Loader.”

A computerized paving system based on the use of a global navigation satellite system (GNSS) and zone laser technology. Based on 3D design data and position information received from GNSS, paving machines such as motor graders and asphalt pavers are automatically controlled with high accuracy.

This system uses an auto tracking total station to automatically control the height at which pavement is laid down and leveled by paver. As the control range is narrower than that of GNSS technology and the equipment is easy to set up, the system is suitable for rationalizing small- and medium-scale paving operations, reducing the need for skilled labor for such operations, and carrying out high-precision construction work.
