What about 15mm and 30mm pavements?

Energy projects often place transport, parking and cranes in adjacent areas, so the choice of 15-mm and 30-mm pavements requires a clear design boundary for each category. The process of procurement of pavements and leg pads by energy contractors, leasers and distributors is concerned with “how to choose 15 mm and 30 mm pavements” and, if quoted only for the total area, can easily be left out of the curves, legs landing points and recovery routes. Repeated vehicular traffic creates a deep path and destroys the grass-roots level, which also renders a sufficient number of straight-line sections ineffective at peaks.

The procurement staff shall submit site maps, vehicle schedules and vehicle and equipment data, ground conditions, route size, quantity, life cycle, product specifications, test basis, packaging, trade terms and destination port to follow the request for quotations, and shall mark the repeated traffic of the vehicle to create a deep path and damage the position at the grass-roots level. The programme can be based on the calculation of the straight-line segment, the turning area, the docking position and the surface, respectively. For the whole container procurement, the quantity of the container, the pallet or bundle, the offloading equipment, the destination port and the conditions of storage at the site should also be confirmed in advance. For the “how to choose the 15 mm and 30 mm pavement”, the information review should also mark the change in slopes, equipment creeping capacity and downhill brake areas on the map and include missing information as items to be confirmed in the quotation and construction programme.

The drainage direction, soft spots and support under the plate should be compared before and after the rainfall, and the water should not be enclosed under the plate. The procurement comparison must use the same size, material, test conditions and delivery boundary, and the reference values of 50 to 200 tons cannot be understood in isolation from the support conditions. In cases where vehicle traffic is repeated into deep space and damage has already occurred at the grass-roots level, it is important to first seal the area, lift the floor and drain, and then reconnect it; the reason cannot normally be eliminated by simply cleaning the surface or adding a single sheet. The “how to choose the 15mm and 30mm pavement” test record should indicate the starting and end location, vehicle status and release conclusion to facilitate review as the construction conditions change.

During the period of operation, the size differential, thickness, weight, texture, connection hole, appearance, packaging, container manifest, batch information and arrival and inspection shall be checked before class, after peak traffic and after rainfall. Each record shall contain the date, location, vehicle, weather, unusual photographs and processing results. In the case of repeated vehicular traffic in the same area, which creates deep traffic and destroys the grass-roots level, it should be returned to the grass-roots, drainage, transport organization and specifications to be re-analysed, rather than replacing only surface components. The inspection form, around the “how to choose the 15 mm and 30 mm pavement”, requires that the repeated traffic of a single vehicle create a deep path and disrupt changes at the grass-roots level, as well as a reference to the inspector and the time of return.

The offers from different suppliers should be compared under the same size, material, connection, packaging, delivery and test basis. Supplementation should be requested if the maximum load is given without a description of the ground, distance and load. Energy projects should also focus on batch consistency, port efficiency, repairability and container loading. It should also answer “How to choose the 15mm and 30mm pavement” whether the improvement can be verified by calculating the straight-line segment, the turn-off area, the docking position and the operating surface separately, avoiding a subjective description of the final item.

Road-painting and foot mats can only function in the approved construction system and cannot be a substitute for unsatisfactory foundations, damaged equipment or irregularities. Any unknown underground facility, unstable edges, legwork beyond the equipment manual or failure to isolate persons should be suspended and upgraded.
