What is the calculation method of geogrid?
- Steel plastic grille, plastic grille thickness of about 2-3, the thickness of the glass fiber grille thinner; grams of technical indicators are also reflected inVolume: Volume II: RR*H cylinder algorithm can also estimate a cuboid length * width * height weight algorithm: unit weight * total areaExample: two way plastic grille 30-30KN width of 4 meters, a length of 50 meters, the volume of the volume of 4, the diameter of 35-41cm, some volumes are not rounds
Which floor is paved on the roadbed
- Fixed grid end, by laying machine or manual will grill slowly pulled forward each shop, shop 10 meters long artificial investigation at a time, until a volume grating puwan, put the next volume, operation with; 3, ground shop: Volume long unit as the laying of the long, should be covered grille with long period, then the overall check again laying quality, then laying the next paragraph, a laying, grille grille to overlap a grid spacing for the lap length, tie fixed line continues to spread second section direction.s
What is the number of tensile elements of Geotextiles
- The number of tensile units in the test is the number of holes or the number of squares in the width of the test. For example, geotechnical geogrid 1m width of 25 holes, stretching the number of units is 25, the width of the sample is 200mm with a hole of 5, the number of tensile units of the sample is, C=Nm/Ns c=25/5=5 personal understanding is not necessarily more thans
What is the action mechanism
- Glass fiber geogrid / glassgrid mechanism of reflective cracking is due to the old concrete surface layer in the vicinity of the joint or crack of large displacement caused by the asphalt overlay above appear stress concentration caused by the. Glass fiber geogrid has been developed rapidly in recent years, and is widely used in asphalt pavement, especially used in asphalt overlay to reduce reflection cracks. Texas Traffic College of AM University in Canada with its unique overlay tester of glass fiber geogrid reinforced cover did a lot of tests and experiments show that the reinforced asphalt specimen cracking resistance than the unreinforced specimens two times. Wollongong Municipal Bureau of New South Wales, Australia has conducted on-site tests of glass fiber geogrid, PP geogrid, geotextile and thickness of asphalt concrete surface layer of reflection crack control products, the conclusion is glass fiber geogrid laying convenience, control effect of reflection crack is the most significant, and the cost is moderate. Therefore we should promote the application. Due to the reinforcement effect of glass fiber geogrid on asphalt overlay, so it can be in the premise of effective control of reflection cracks, reduce the asphalt overlay thickness (with and without laying fiberglass geogrid, compared) reduce the cost, and achieved good economic benefit.s

Each side of geogrid is not less than 3 meters, what does it mean?
- Design requirements obviously not for this purpose, I consider is not a few geogrid lap width than the roadbed width of three meters, and then backfill roadbed soil after 60 or 80 cm and then the two sides of the geogrid back.s
