Ceramics material for road improvement

Introduction of ceramics material for road surface pavement

Colored ceramics aggregate for anti-skid pavement TOUGH BAHNTM

  • TOUGH BAHN photo

  • Certified aggregate for NEAT installation method by Japan Technical Association of Resin Pavement

    Certified aggregate for NEAT installation method by Japan Technical Association of Resin Pavement

TOUGH BAHN is colored ceramics aggregate to be installed with thin thickness on asphalt road or concrete road. Thanks to excellent abrasion resistance and color durability, TOUGH BAHN is used for resin based color anti-skid pavement (NEAT installation method) that demand has been rapidly increasing in recent years.

Characteristics

  • Excellent abrasion resistance due to ceramics material burnt at high temperature
  • High anti-skid property can be obtained due to moderate angular shape
  • No color change happens in use due to uniformly coloring to the whole aggregate
  • Excellent workability due to high affinity with resin binder

Special heat shield ceramics aggregateTough Barn® Gray-White

Heat shield TOUGH BAHNTM gray-white

Characteristics

TOUGH BAHN gray-white is heat shield aggregate containing special pigment to reflect infrared radiation.
TOUGH BAHN gray-white can prevent heat absorption from sunlight and inhibits increase of temperature on road surface while keeping the original characteristics of abrasion resistance and anti-skid property of TOUGH BAHN.

Brands

  • TOUGH BAHNTM gray-white  A1-size (Other color products are under development)

Evaluation example of heat shield property

Special heat shield aggregate “TOUGH BAHN gray-white” has similar effect of decreasing temperature on road surface to that of “TOUGH BAHN white “ despite colored gray.

  Hear shield TOUGH BAHN gray-white TOUGH BAHN white
Appearance of aggregate TOUGH BAHN gray-white TOUGH BAHN white
Lightness of road surface  L* 56 74
Decreased temperature of road surface
(difference from unexecuted road)
-7.4℃ -7.7℃

【Evaluation method】
Specimen is prepared on dense-graded asphalt according to RPN-301(standard condition of Japan Technical Association of Resin Pavement, without top-coating).Then, the evaluation of decreased temperature is measured by indoor lamp irradiation method (Conforming to the regulation of construction bureau of metropolitan Tokyo).

Example of installation

Abrasion resistant white ceramics powder “TOUGH COORE®"

Abrasion resistant white ceramics powder “TOUGH COORETM"

TOUGH COORETM photoTOUGH COORE is white powder made from hard ceramics obtained by melting alumina・zirconia at high temperature. By adding TOUGH COORE to coating material, excellent function of abrasion resistance can be obtained. High performance is expected when used with coating material at special strong abrasive area such as road and floor. In addition, TOUGH COORE can be used as extender pigment due to its low coloring ability.

Brands

Two brands with 2 different particle size are prepared.

  Lightness L Particle size(μm)
D50 D90
TOUGH COORE P#325 96 13 40
TOUGH COORE P#200 96 24 60
