Improved Type II asphalt concrete, semi-flexible compositions consisting of opengraded asphalt injected with cement milk, and concrete compositions are among
the most commonly used types of conventional heavy traffic pavement. However,
Improved Type II asphalt concrete and ordinary semi-flexible compositions areoften susceptible to cracks and dents under the stress of vehicle engine vibration
or static loading, eventually leading to surface layer destruction.

Super As-Con (Asphalt Concrete) Pavement series
Ultra Pave H
Ultra Pave H is a paving composition that provides goodfluidity resistance, oil resistance and resistance to stationary
steering while also offering levels of static load bearing
capacity that are equivalent to concrete paving. It is a semiflexible paving composition that combines the durability ofconcrete paving and the flatness and deflection complianceof asphalt paving.

Super Epo As-Con
Super Epo As-Con is an epoxy resin-added asphalt paving
composition that offers good fluidity resistance, oil resistanceand resistance to stationary steering while providing superior
deflection compliance. Unlike ordinary semi-flexible paving
compositions, Super Epo As-Con does not generate
unwanted particles, making the paved surface ready for
traffic in only several hours after installation.

Super Poly As-Con
While offering similar physical properties as those of Super
Epo As-Con, the use of thermoplastic polyester resin additivein Super Poly As-Con makes the composition as easily
installable as ordinary asphalt paving. The composition canalso be reheated for compaction.

Low Noise / Porous Asphalt Pavement‫ اﻟﺨﺎﻓﺾ ﻟﻠﻀﻮﺿﺎء‬/ ‫ﺗﻌﺒﯿﺪ اﻟﻄﺮق ﺑﺎﻷﺳﻔﻠﺖ اﻟﻤﺴﺎﻣﻲ‬Porous Asphalt Pavement

Normal Asphalt Pavement

OutlinePorous Asphalt Pavement (AMENl-PHALT S Series) has the function of absorbing noise and draining water.
This pavement is applicable to heavy traffic roads as the pavement provided with characteristic of low noise and rapid
draining. The characteristic is acquired by improvement of high temperature stability and durability of high viscosity
improved asphalt. The series is consisted with type S focused on draining effect, type SS focused on low noise effect andtype SSS which has double layer structure having type SS as upper layer and type S as lower layer to improve the both oflow noise effect and draining effect.

The advanced image analysis system will detect human presence even when only a person’s foot gets inside the defined
detection area. The yellow frame shown above indicates that the system has recognized human presence in the control
distance range so that the vehicle will be automatically slowed down by the control unit.
The image analysis system has superb object recognition capability so that humans will be dependably distinguished frominanimate objects during dark hours. The system has been validated to work reliably in poor visibility conditions such as rain,backlight shone from behind the objects, and twilight hours.

Factory-built components offer a consistent track surface
quality free of weather conditions during construction. The
one-piece molding process helps prevent tile separation,
contributing to significant durability improvement.
Elimination of the piece-by-piece tile gluing process byhand also greatly helps reduce work time.
With a choice of different tiles, the process caters to avariety of tracks from low-μ to medium-μ surfaces.
