| 404019000 | Anti-slip surface | 6 |
| 20090162143 | Wavy Tactile Walk Path - The present invention provides a pattern-changing walk path on top of which some groove lines and some raised ridges or dots form an anti-skidding layer for children's play and games. The modular design may be disassembled into the units for storage, taking up little room since they can be stacked together, and can be securely attached to one another when put together for use. | 06-25-2009 |
| 20110142537 | Assembly for covering a trench - An assembly suitable for temporarily covering a trench comprises an anti-slip tile ( | 06-16-2011 |
| 20140212215 | Walking Exercise Park with Man-Made Hill - The invention is a walking exercise park with a man-made hill. The hill can contain one or more slopes and steps that can be selected and walked or jogged. The goal of the man-made hill is to conveniently provide improved and expeditious health and fitness benefits as compared with ordinary park or level track walking. A person will be able to easily manage walking path elevation changes and have complete control over their workout on a concentrated footprint in a safe environment. The park can also be used for sports or athletic training or physical therapy and injury rehabilitation. The park can be lighted or covered or enclosed. | 07-31-2014 |
| 20140219717 | Structural Underlayment Support System And Panel For Use With Paving And Flooring Elements - A paving system for paving or flooring includes a top layer of a plurality of paving elements, and an underlayment support layer of a polymeric material configured into panels. The panels are suitable to support the paving elements, the panels having a generally planar support surface. | 08-07-2014 |
| 20160024723 | DRY POLYMER CEMENT OVERLAY FOR TRAFFICKED PAVEMENTS - A dry polymer cement overlay for trafficked pavement substrates (both asphalt and concrete). The dry polymer cement overlay is a thin overlay that can handle the load of traffic in a relatively short time and has a relatively long life cycle. Moreover, the dry polymer cement overlay can hold aggregate that is applied on the surface of dry polymer cement overlay before it cures in order to provide a friction surface. A stencil is used during application of a dry polymer cement layer to provide a patterned overlay that includes patterns separated by gullies. The patterned dry polymer cement overlay exhibits improved performance including short and long term substrate adhesion, reduced risk of delamination, safety through improved surface runoff and enhanced visibility, improved macro and micro friction, reflective crack management, and withstands higher deflections under heavy loads. The patterned dry polymer cement overlay may also reduce noise and improve aesthetics. | 01-28-2016 |
| 404020000 | Abrasive impregnated | 1 |
| 20140161524 | Sealcoat System - A sealcoat system for providing a sealcoat that is free of silica. The sealcoat system generally includes providing a sealer, crushed glass, water and an additive, mixing the sealer together with the crushed glass, water and additive to form a sealcoat composition, and applying the sealcoat composition to a road. The crushed glass is preferably comprised of soda-lime glass and is further preferably comprised of container glass used in the production of bottles and jars. | 06-12-2014 |
