Pavement durability is always of concern in roadway projects, for safety, cost control, and responsible future planning. Geosynthetics offer a number of solutions to improve roadway performance, including prevention of reflective cracking. Machina-TST has made a strong impression in the road-building market with products such as ASPHALTEX (a PET, bitumen-coated geogrid) and DUALTEX (a geogrids-geo... »

By Ray Myers – The benefits of asphalt interlayers are documented going back over 40 years. Interlayers delay reflective cracking and form a moisture barrier when properly installed using liquid PG asphalt. A dry aggregate base maintains its’ designed load bearing capacity. Manufactures have continually added new and improved interlayers (paving mats, paving grids, and composite paving grids) to p... »

Last year, Titan Environmental released two fiberglass geogrid products, TE-FGP and TE-FGC, which is a geogrid-geotextile composite. The products were engineered with a  polymer coating to endure higher temperatures (up to 900° F) and with very low shrinkage potential, thus keeping asphaltic systems rigid. Now, the company has released the next phase in its geogrid development: a polymer-coated fi... »
