Environmental Engineering

We have developed products and methods considering human life and the earth’s environment by utilizing NIPPO’s original technologies.

In order to meet the expectation of society, NIPPO operates by our policy to “strive for continuous improvement of environmental conservation activities, and contribute to realization of the sustainable society where environmental preservation and economic activity are compatible." Taking advantage of our original outstanding technical capabilities, NIPPO proactively promotes development of materials, products, and pavement construction methods which consider human life, cities, and the earth’s environment.

Major lineups of environmental pavement and materials

The tree of environmental burden reduction

Reduction of CO2 emissions
1 ECO FINE manufacture temperature of heating asphalt mixture by 30 ℃, which exerts effects in CO2 emission reduction.
Strengthening of pavement structure
2 COMPOSITE PAVEMENT  
Improvement of durability
3 SMAC Pavement using a special gap graded mix which excels in durability.
4 MIRAFALT It is equivalent to Modified Asphalt II shown on the pavement construction guide. It excels in plastic flow and abrasion resistance.
Life extension of existing pavement
5 THINLAYER SMAC Thin layer pavement with the special asphalt mixture of 5 mm of the maximum particle diameter.
6 NIPPO CARPET A surface treatment construction method which overlays existing road surface with hot asphalt mixture in order to recover the road surface quality of community roads.
Effective use of industrial by-products
7 GERASFALT  
8 SLAG ASCON Materials using other industrial by-products, such as molten slag and a glass cullet, as aggregate.
9 MIX RAGA Blocks and plates made from recycled waste glass.
10 LRE PAVE Low rebound resilience pavement for artificial lawns using recycling rubber.
Recycling of pavement materials
11 FRB A method that crushes existing asphalt mixture on the road and reproduces a new road surface by combining it with lower layer materials.
12 SURFACE RECYCLING A method that heats and reproduces the surface of pavement whose functions such as flow and friction are diminised.
13 REGENERATED ASPHALT MIXTURE  
Effective use of waste wooden construction materials
14 PERFECT CLAY C&C Clay pavement mixed with soil and the bark of Japanese cedar or cypress.
15 PERFECT WOOD CHIP The effective use of wood chips from thinning.
16 PERFECT CEDER Woody system pavement by softwood skin fiber, rough sand, and asphalt emulsion.
Reduction of traffic noise
17 PERVIOUS It uses permeable mixture on a surface and drains rain water promptly. Air void ratio is high and road surface noise can be reduced.
18 SUPER SMAC Road surface noise is reduced by air void on the surface of pavement.
Control of urban-type floods
19 AQUA PERVIOUS Rain water is temporarily stored inside the pavement body and then flows into the earth efficiently.
20 PERMEABILITY PAVEMENT Rain water is made to penetrate below subgrade through a pavement body.
Control of road surface temperature rise
21 PERFECT COOL A heat shield layer is coated on the surface of pavement, and an infrared region among sunlight is highly reflected or reflected with retroreflection.
22 COOL PERVIOUS A heat shield layer is coated on drainage pavement and the rise of road surface temperature is controlled.
23 COOL POLYSEAL Water-retentive grout is filled into air void of open graded asphalt mixture for semi-flexible pavement.
24 TREE PLANTING BLOCK PAVEMENT Pavement which lays blocks at a fixed distance and turfs the crevice.
25 GOLPLA.NEO Lawn protective blocks of honeycomb structure made from reproduction polypropylene.
26 PERFECT CLAY L "Pavement of soil" using special soil texture improvement material which cannot be easily influenced by weather.
Vibration control / Freeze control / NOx absorption
27 BILO PAVE Asphalt pavement that can reduce the traffic vibration on the surface/binder course without strengthening subgrade or base course.
28 RUBBER ROLLED ASPHALT Semi-flexible icy-road-preventive pavement using special artificial rubber aggregate instead of pre-coated crushed stone which are sprinkled and pressed on the road surface.
29 NOx REMOVE PAVEMENT It decomposes and removes NOx emitted from an automobile by oxidization action of the photocatalyst under ultraviolet rays.
Soil purification
30 Remediation of Soil & Groundwater We foresee the risk of soil and groundwater contamination and propose countermeasures.
Dustproof solidification agent
31 TEFIX Soil stabilizer developed from dust prevention technology using Teflon resin.
